Hey guys it's Kerry lots of amazing sea animals
today Do you know that fish don't actually breathe water they filter dissolved oxygen from it
Koolasuchus these amphibians were top aquatic predators similar to crocodiles today They
became extinct towards the end of the early Cretaceous when temperatures were rising and
this gave crocodiles the opportunity to take over Puffer fish can inflate into a ball shape to
evade predators they fill their elastic stomachs with huge amounts of water or a
ir Moray eel
it has a very strong sense of smell and uses this strong sense of smell to find food or
a spawning site Please subscribe and turn on notifications Deinosuchus it has been
estimated to have grown to about 11 m in length and weighing 6 to 7 tons by
far exceeding any modern alligator or crocodile Spiny Lobster can be easily
distinguished from true lobsters by their very long thick Spiny antenna and by the
lack of chelae or claws on the first four pairs of walking legs although th
e females of
most species have a small claw on the fifth pair Clawed Lobster they have long bodies
with muscular tails and live in crevices or burrows on the sea floor Three of their five
pairs of legs have claws including the first pair which are usually much larger than the
others Lobsters are invertebrates with a hard protective exoskeleton like most arthropods
lobsters must shed to grow which does leave them vulnerable During the shedding process several
species change color although l
obsters are largely bilaterally symmetrical like most other
arthropods some genera possess unequal specialized claws fFying fish can make powerful self-propelled
leaps out of the water with their long wing like fins Enable gliding for considerable distances
above the water's surface the main reason for to this behavior is thought to be to escape from
underwater predators although these periods of flight do expose them to an attack by avian
predators The record for a flying fish being able t
o glide over the water is 45 seconds in
flight Spotted eagle ray they are potentially dangerous to humans due to the venomous tail
spines that can inflict serious wounds Marbled Stingray this Ray is not generally aggressive but
is known to be responsible for at least one human fatality the infamous Steve Irwin Crocodile Hunter
Cownose Ray they are found lying on the bottom or above coral reefs in sheltered bays as well as out
in open waters They swim together to stir up the sediment which e
xposes the clams and oysters
which they feed upon sometimes they are seen jumping out of the water and landing with a loud
smack Manta ray they have no teeth or grinders no tail stinger but rely on speed to survive they can also
leave out of the water they are identified by head fins which when rolled up look look like horns and
when unurled they act like a funnel for the mouth Blue spotted Ray they are bottom feeders they
settle themselves down over their prey trapping them against the sub
strate with their disc then
flexing their disc flaps and maneuvering the victims into their mouths Most rays live in
the sea but some can be found in estuaries As a form of defense rays have electric organs, While
others have venomous spines Usually rays will swim out of harms way if approached however they
can give a nasty sting which could prove fatal Never swim over the top of large rays they think
you are a predator and are likely to whip their tails in defense Fish are cold blooded unl
ike
us who are warm blooded there is an exception though tuna and Mackerel sharks have warm blood
like us a fish's slimy scales helps them glide through the water more easily Most fish don't
have eyelids the only fish that can blink is a shark Sea turtle unlike other turtles sea
turtles cannot retract their flippers and head into their shells Their streamline
shells and large paddle-shaped flippers make them very agile and graceful swimmers in the
water Their rear flippers are used as rudd
ers for steering The seven existing species
of sea turtles are flatback, green , hawksville, leatherback, loggerhead,
Kemp's Ridley and Olive Ridley sea turtles Kemp's Ridley sea turtle it has
a triangular shaped head with a slightly hooked beak adults are generally a
grayish green color on top with a pale yellowish bottom shell The hatchlings are
darkly colored on both sides Each of the front flippers has one claw while
the back flippers may have one or two Leatherback Turtle it is the
l
argest of all living turtles and the heaviest non-c crocodilian reptile
reaching lengths of up to 1.8 m which is nearly 6 ft weighing 500 kg they are
easy to recognize instead of having a bony shell their carpes is covered by
oily flesh and flexible leather-like skin green sea turtle they live part of
their life in the open ocean and they're most often encountered in shallow lagons and
coral weaves where they feed on sea sponges red slided Turtle they have poor hearing
but good vision and
are very sensitive to vibrations when startled or threatened they will
quickly slide off rocks or logs back into the water marine reptiles these are the reptiles that
can live in and around the Seas for example sea turtles and saltwater crocodiles sea turtles
have been alive since dinosaurs lived on our planet most sharks are coldblooded but some
like the great white shark are warm blooded Mega Laden its bite force would have been five or
six times more than a great white shark it's jaw wou
ld span 2.7 to 3.4 M wide easily big enough
to swallow two adults side by side these Jaws were lined with 276 teeth sea star most have
spiny skin and five arms although some can grow as many as 50 arms the arms are covered
with pencil-like organs and suckers Hors Shake crab is a hard Shen vertebrate found on the
seaf Flor in warmer shallow Coastal Waters it has a hard outer shell five pairs of legs and
a long thin tail which it uses for changing direction when swimming it is actually not a
crab and is more closely related to spiders and scorpions shastasaurus it is an extinct genus of iosaur that lived during the late tricic
period it grew to 7 m or 23 ft in length goblin shark it has a distinctive
shaped snout and an impressive array of long pointed teeth it has a shovel like snout
flabby body and a tail with a weakly developed lower lobe one of the distinctive features
of the goblin shark is its petable mouth the mouse can retract to a position under the eye or
extend forw
ard under the snout when feeding the goblin shark extends its jaws forward faster
than any other species of shark to catch its prey prey would include bony fishes squids
and crustations the underside of the snout has many pores that are external openings there
is electricity detecting organs here the goblin shark most likely hunts its prey by detecting
electric Fields plos serus ammonite was a type of seop pod that Liv your the early Jurassic
Period the most distinctive features of these cr
eatures were their tightly cured shells
which featured prominent Wes and spikes ammonite these MST are more closely related
to living colloids octopuses squid and cattle fish previto cerus they are an extinct genus
of ammonite they were fast moving neonic carnivores basilosaurus had primitive dentition
and skull architecture the rest of the Slender elongated skeleton was well adapted to Aquatic
Life it attained a length of about 21 m which is 70 ft with a skull alone as much as 1 and
1/2 M
basilosaurus was common through the late ecas the Primitive skull would have had a small brain basilisk was a mythological beast and said
to have the power to cause death with a single glance you can bend the Basilisk into different
shapes according to Legend This snake was only 30 cm or 12 in in length and it was so venomous it
leaves a white trail of deadly venom in its wake and its gaze is likewise lethal wey Sea Dragon
they are only found in Australian Coastal Waters or though they appe
ar to be seaweed they are
actually bony fish pipe fishes and seahorses are unique in that the male gives birth the female
deposits their eggs after fertilization into the M's brood pouch giant squid and some other large
squid species maintain neutal Bucy and sea water through an ammonium chloride solution which is
found through out their bodies and is lighter than sea water like other sephila squid are
intelligent animals squids have a headlike structure with sense organs and brains in thei
r
front end although the squids like exterior shells they have a vestigial shell inside made of kiten
which is spelled c h i t i n often the m will die a short time after mating and the female will
die once she has released her eggs because of this squid usually only lay eggs once they do
not live very long most of them live for only one or 2 years all squid have a mouth with a
regular and Jet proportion with the siphon from the mantle the regula is a scraping organ in the
mouth that scrap
es nutrients from food sources in lasma surus it is a genus of pleasur that lived
in North America it measured 10.3 m in length a lesma surus would have had a streamlined body with
paddle-like limbs a short tail a small head and an extremely long neck the neck alone was around
7.1 m M the skull would have been slender and triangular with large Fang likee teeth at the
front and smaller teeth towards the back their long neck enabled them to approach a should of
fish and stick their head in an
d pluck one out quickly Tenny stopus these marine reptiles grew
up to 6 m in length and had unique NE composed of 13 extremely elongated vertebrae and stra
likee ribs Tanny stopus was not a fast swimmer so often walked along the seabed and used its
long neck to get within range of prey without being noticed hydrosaurus is an extinct genus of
a lasos Sur plesiosaur from the upper Cretaceous it has one of the longest necks relative to
total length Tyler curus is a genis of mosesa a large pred
atory Marine reptile closely related
to Modern monitor lizards and to snakes it lived during the lake Cretaceous it was one of the
deadliest Hunters of its time it had a long snout and hinged Jaws which gave it a fearsome
bite this Marine reptile propelled itself through the water with its powerful flat tail and stered
with its four paddle like flippers its mouth was lined with rose of cone shaped razor sharp teeth
and this colossal creature was always ready to Chomp marine reptiles are rep
tiles which have
become secondarily adapted for an aquatic or semi- Aquatic Life in a marine environment
some extent or living varieties are the sea turtles sea snakes Marine iguana and the
saltwater and American crocodiles some of the extinct marine reptiles became so well
adapted to a Marine lifestyle they were incapable of venturing onto the land and gave
birth in the water living species such as sea turtles and saltwater crocodiles returned to
shore to lay their eggs some marine reptil
es also occasionally rest and bask on land of the
12,000 extant reptile species and subspecies only about 100 are classed as Marine reptiles blue
ringed octopus they are stunning when they are alarmed these animals will show off theonomous
iridescent blue rings that cover their body and arms baby octopus octopus are ocean creatures that
are most famous for having eight arms and bulbous heads they have three hearts
and blue blood they squ ink to deter predators and being boneless they
can s
queeze into or out of tight spaces they are quite intelligent
and have been observed using toes octopus have an excellent
sense of touch their suckers have receptors that enable an
octopus to taste what it is touching the only hard part of their bodies
is a sharp parrot-like beak that is on the underside where the arms converge
octopus have powerful jaws and venomous saliva when octopus is made they die soon after octopuses have catlike tongues it's
called a radula and it's a tongue likee
ribbon lined with rows of tiny teeth
that are replaced as they wear down Sally like fot crab they have the ability
to climb vertical slopes and exceptional agility blue swimmer crab they are
powerful swimmers and voracious hunters and scavengers crustations include crabs lobsters
prawns shrimp and crayfish lobsters have blue blood and they can live for over
100 years quish walk forward but swim backwards spiny lobsters are thought to
be social animals and Gathering groups of 12 or more the
y migrate in long chains
across the ocean floor up to 50 lobsters at a time crocodile the two species with the
most well-known and documented reputation for praying on humans are the Nile crocodile and
saltwater crocodile crocodiles have a unique body form that allows the eyes ears and nostrils
to be above the water surface while most of the animal is hidden below the tail is long
strong and massive and the skin is thick and plated a crocodile hling emerges from the egg
with a length alrea
dy of up to 30 cm or 12 in a young crocodile grows about 30 cm each
year for the first 4 years frog fish they are small short and stocky and like this one
covered in spuls and other appendages to Aid in camouflage Ang fish this a light that emanates
from the end of the fishing rodlike extension on its for forehead it uses this surprising adaption
to lure prey out of the dark and close enough for its razor sharp Jaws to strike salmon are
anadromous they hatch in the shallow gravel beds of ri
vers as an adult they return to the Sea and
return to their freshwater birthplace to reproduce koi fish they are a relatively small member of the
carp family they feed on Ben thck organisms and plants koi fish in Japan they stand for anything
that's good luck Prosperity vitality and Longevity their length is usually up to about 28 cm and
they are found in braish and and fresh waters drainage ditches lakes and rivers in many
places they spread from Asia throughout the world large Mouse Bass
the upper jaw or makilla of
a large Mouse bass extends beyond the rear margin of the orbit that's where they get their name
from they feed on crustations crayfish fish and frogs pirana they are aggressive predators
that lur in vegetation and Ambush and Chase prey they sometimes work in groups to kill larger prey clown trigger fish is a demersal
marine fish the head is large and represents approximately 1/3 of the body length the
mouth is small terminal and has strong teeth Queen trigger fis
h they are aggressively
defensive of their territory and can inflict a strong bite especially during the
breeding season it can change color to match its surroundings or if subjected to
stress the queen trigger fish has a favorite food sea urchins which they turn over and
attack from underneath where the spines are shorter let's talk about sharks sharks of
fish that have skeletons made of cartilage rather than bone making them lighter and more
buoyant in water over millions of years they h
ave developed extraordinary senses to help
navigate and detect prey there are about 500 species of sharks in the world dong they are
referred to as sea cows because they use their strong Clift upper lips to grad on sea grasses
they eat both day and night locating their food with the help of Co sensitive bristles on their
upper lip manate tees never leave the water but typically come up for air every 5 minutes their
powerful tail fluk propels them through the water the manity has a large fle
xible prehensile
uper Li used to gather food and eat and for social interaction and communication
manatees have shorter snouts than the dongs sea lion they are part of the pipet group
that also includes seals and W resses which is why sea liines and seals are often confused for the
same species however an easy way to distinguish between the two is to observe how they stand and
move on land sea lions have long flippers that they can stand on while Seal's flippers can barely
reach the ground
sea lions are predators they consume large amounts of fish and hope to regulate
prey species populations they are also prey however and serve as an important food source for
large animals like great white sharks hammerhead sharks blue sharks and killer whales as they
live both in water and on land they also carry important nutrients from the ocean to the land
fertilizing the soil on which they rest a baby fur seal spotted seal they preferred
habitat is the edge of the pack ice in areas of
loose flows
while harbor seals avoid sea eyes H seal adults have pure black eyes it has a silver gray fur covering its body with
black half or Wishbone shaped markings dors another way to tow the
difference between a sea lion and a seal is that only the sea lion
with the longer flippers has visible ears the main predator of seals are killer whells polar bears leopard seals
large sharks and of course humans mammals like sea lions seals and W rasses
are called Penny pets as they have winged
feet elephant seal they take their name from the
large proses of the adult male reminiscent of an elephant's trunk and considered a secondary
sexual characteristic the fo's prosis is used in producing extraordinarily loud roaring
noises especially during The Mating Season males display their dominance by showing
their noses making loud vocalizations and altering their postures they fight each other
by raising themselves and ramming each other with their chest and teeth best to keep your
di
stance elephant cells can out run a human on Sand seahorse they possess swim Bladers to remain
buoyant in the water and utilize their gills to breathe they are unusual animals
with their hores shaped head eyes like a chameleon which can move
independently and a prehensile tail they use their elongated snaps
to suck in Plankton and small crustations blue sea dragon they are pelagic they
float upside down by using the surface tension of the water to stay up where they are carried Along
by th
e winds and ocean currents polar bear because of the intensity of competition between adult
males is significant and since larger males are more likely to out compete smaller ones for
mating privileges through natural selection over the longer term adult males have evolved
to be roughly double the size of females they are found throughout the Arctic region the polar
bear travels long distances over vast desolate expanses generally on drifting Oceanic ice flows
searching for seals its primar
y prey except for one subspecies of grizzly bear the polar bear
is the largest and most powerful carnival on land it has no natural predators and knows no
fear of humans making it an extremely dangerous animal their broad feet have hairy Souls to
protect and insulate as well as to facilitate movement across ice as does the uneven skin
on the SES of the feet which helps to prevent slipping they have strong sharp claws and this
is important for gaining traction for digging through ice and for
killing prey murus is a
marine reptile that liveed during the lake Cretaceous it had a streamlined body an elongated
Tail ending with a downturn supporting a two loed fence and two pairs of flippers mososaurus was
part of a group of mososaurus known as aquatic squamates the largest discovered specimen
of mososaurus had a lens of up to 17 M or 56 ft mesosaurus was a c aquatic Hunter and their
prey was most likely fish other marine reptiles birds terrasaurs smaller mosasaurs and maybe
even
L Dinosaurs the teeth of the mosasaurus were shaped like sharp spikes allowing them to
grip and hold on to Slippery prey they double hinged jaw allowed mososaurus to swallow
its prey whole they spent most of their time near the ocean surface much like modern
Wales since they breathed air in a similar fashion plier sorus had teeth that
were triangular in cross-section their diet would have included
fish zop pods and other marine reptiles kinosaurus was a marine reptile a pliosaur it
had an
elongated head a short neck a stiff body propelled by four flippers and a relatively
short tail chronosaurus reach speeds of up to 40 mph or 65 km per hour their big teeth
enabled it to crush the shells of the huge shellfish called ammonites that lived in the
same sea and its sheer size meant that it could have eaten just about anything smaller
than it including other plesiosaurs and pliosaurs it had a particularly large head and teeth that were roughly the
same size and shape as a small ba
nana its length is estimated to
range from somewhere between 8 and 12 M the tail of the Kronosaurus is too short and
taped to be really useful in moving fast over a distance its short neck would have made
any sudden movements of its head impossible but its flippers were large and powerful
enough to allow it to D forward suddenly to capture its prey it was more likely
to Lunge after its victims than chase them cuttlefish when a shrimp or fish is in range the Cuttlefish a and shoots out
its
two tentacles to seize its prey they belong to the class seopa
which also includes squid octopus and nautiluses giant cattle fish the giant
Australian Cattle fish is the world's largest cattle fish and like many other the
seop pods it is able to camouflage itself exceptionally well reef squid they have long
oval fence that extend along the edge of its mantle giving them a superficial similarity to
cattle fish anomal carus it is distantly related to modernday arop pods including crabs
and l
obsters it didn't survive the mass extinction it resembles a giant shrimp it had
no legs but swam by flexing its segmented body and waving the flaps on its sides Nautilus
has a shell that protects it and acts as a buoyancy organ they have survived relatively
unchanged for hundreds of millions of years is Nautilus pompilus it
has a beautiful pearly show inside cus was a genice of nooid seop pod
from the Permian period it resembled a spiny ammonite I'm going to talk about Wales they are
full
y aquatic open ocean animals they can feed mate give birth suckle and raise their young
at Sea they range in size from 2.6 M to 29.9 M the sperm well is the largest
tooth predator on Earth the blue well is the largest known animal that has ever lived bellam knite they are an
extinct order of squid-like spilop PODS that existed from the lake Triassic to Lake Cretaceous or theris was an ancient
spilop pod that lived about 370 million years ago the name means straight horn
referring to its lon
g straight conical shell Trill bite they are extinct marine
arthropods and one of the earliest known groups of arthropods Exel belongs to the
salamander family it has external gills humpback whale they can grow to over 18
m in length and live up to 90 years humpback Wells have some of the longest migrations of any
mammal with some population swimming over 8,000 km between breeding and feeding GRS they F to
feed for tiny Crill or small pelagic fishes and are totally harmless to people blue w
hale they
have the largest penis on earth an erect blue whale penis is 12 in or 30 cm in diameter and
10 ft or 3 m in length it is fibroelastic like those of the blue Well's artiodactyl relatives
the retracted penis Curves in an s-shaped Loop and stays inside the body when erect it Peaks
out of the genital slit blue Welles also have a distal spiral valve as a spermatic tube cations
do not have scrotums like to rest your Maman males do blood goes directly to the testes the
females have a lo
ng ful and two nipples on each side Liv atam is an extinct genus of macro
repor sperm well containing one known species it had functional enamel
coated teeth on the upper and lower Jaws great white shark like many other sharks
have rows of serrated teeth behind the main ones ready to replace any that break off when
the shark bites it shakes its head side to side Hing the teeth sore off large chunks of Flesh
great white sharks like other mackerel sharks have larger eyes than other shark spec
ies in
proportion to their body size the iris of the eye is a deep blue instead of black Ora it's
also called the killer whale it is a toothed whale belonging to the oceanic dolphin family
of which it is the largest member Mega Laden it's teeth grew to 16 cm or 7 in in length
and it would have fed on large prehistoric Welles please stay and watch another video with
