"Animal Big Star" "Arothron hispidus"
Pufferfish without spikes It looks so round and cute but its eyes still make people feel nervous Do you know why are they called pufferfish? Why is pufferfish called pufferfish? "Narrator: Chen Shu-Ping"
because when the ancients discovered it they found it in the river The pufferfish is actually able to live in sea water as well They can survive in both water So when it was found people just name it Pufferfish As for now we just kept the name call it Puffer
fish "Diodon holocanthus "
Tiny Pufferfish keep waving their fins like dancing in the sea Since it is called Pufferfish Is it the same as a dolphin? are mammals? Pufferfish and dolphins are different "Caretaker Zheng Qiao-Fang"
Pufferfish is a fish it breathes with gills Dolphin is a mammal like us they breathe with lungs Four main types of pufferfish in sea 4-toothed, 3-toothed, and 2-toothed and boxfish They look different For boxfish "Diodon holocanthus"
it's kind of boxy Because its skeleton
are square As for more common 4-toothed puffer "Arothron manilensis"
or 2-toothed puftferfish way to tell their difference is mainly by its teeth tooth or spike in its body For 2 toothed it has upper and lower teeth like two pieces of board 4 toothed on the other hand has two on upper and two on lower kind of like a rabbit or a mouse It has four in this way Kind of like a parrot or a mouse pointy they bite like this That's 4 toothed We see its appearance is smooth you can't see its spikes its s
pikes are not obvious For 2 toothed pufferfish its spikes are huge You see it from the appearance It's full of spikes all over its body That's 2 toothed pufferfish As for the three-toothed puffer it is relatively rare in Taiwan It lives in relatively deep water Generally, we breed less of that kind Pufferfish have a strong bite If you accidentally get bitten by it It will break your bones Although it looks small But don't ignore their aggressiveness If you meet them by the sea be careful Now let
's see Pufferfish's body structure Pufferfish are the same as other fish Has 2 pectoral, pelvic caudal fins They mainly use pectoral, pelvic fins to swim forward Tail fin for control the direction Pufferfish we see it blows usually when it is frightened frightened or when it feels in danger it sucks air and water into its stomach "Diodon holocanthus "
inflate itself Instantly increase your body size to scare off the enemy Usually, it lives stably in the water In fact, we rarely see it puff up us
ually we have to scare it for it to inflate For how long is really depends on the species Some stayed puff longer it take an hour or two to start deflation Sometimes it's not that frightened it just blow up a bit When the enemy runs away Or sometimes when we fish it Yes, if we fish it it will puff up but if we quickly take away the net put it in the water about 10 or 20 minutes it will deflate won't stay puffed for too long Because it is not good for it Yes if it puff it can't breathe its gills
are plugged Yes, so it breathes through the skin so it usually unless there is an emergency or enemy is nearby let it feels frightened it keeps puffing Usually as soon as the danger is gone it will deflate Pufferfish's body can't puff for long it's full of spikes Puff is very bad for their bodies because when they puff they can't breathe Do you know not all pufferfish are poisonous But how do we tell poisonous or non-venomous pufferfish Is it poisonous we can see from the appearance recognize at
first sight Because the spikes of 2 toothed it has distinct spikes then we know it's not poisonous The body surface is smooth that kind of 4-toothed are poisonous If the pufferfish is poisonous mainly neurotoxic If we eat a little of it we'll start to have symptoms You'll feel cold in the end, a heart attack The ones we usually get at restaurants are 2 toothed It have spikes But this kind of fish In fact, we can eat it all it is not toxic Normally poisoning after eating puffer fish are from 4 t
oothed pufferfish To cook it, in Japan If they want to cook this usually requires a license a cooking license for the chef to cook it 4 tooth pufferfish is poison especially its guts its gonads and its ovaries Its guts are all poisonous so we cut it lightly if the fluid from guts come out the whole fish can't be eaten So when deal with it deal with extreme careful Although we can see from the appearance to find out if pufferfish are poisonous But it is very easy to make mistake Since pufferfish
are so poisonous why do we still like to eat it so much? Generally speaking like japan we go to japan when being there you want to try fugu feast But in fact, I don't recommended it Pufferfish is poison not only its guts Its skin and blood and its internal organs and so on are all highly toxic For humans to eat it "Arothron manilensis"
is relatively bad the most poisonous place lies in its liver Why do humans eat its liver? Its liver is very rich in omega3 so it tastes very delicious feels like
condensed milk So many people will try pufferfish liver That's actually not recommended Swim, swim, swim, swim Look at my flexible tail fin it's swinging Isn't it funny? Want to know where we are all located? in the waters near Taiwan Can you see us, too? Pufferfish are found at 35 degrees N to about 45 degrees S In hotter areas like area around Taiwan you can find a lot of Pufferfish I finally found you Where did you go? We were just watching our master examing our environment make sure it's sa
fe and clean For pufferfish the suitable temperature is about 23 to 28 degrees We test every day the water quality in our tank measure the dissolved oxygen which oxygen dissolves in water The best is 100% If it's less than 80 % means a lack of oxygen in the water Then we will helping it increase pump some air or increase the flow of water inside Let it have enough oxygen We measure its salinity and pH value It's not good too high or too low because they are marine fish There is a fixed salinity
If the salinity is too low it is also not suitable for them to survive For the pH value like normal seawater pH relatively weak alkaline We'll look at the pH of the water then to judge their water quality today You see there are many types of pufferfish pufferfish in the aquarium How many types are there? In our aquarium mainly two-toothed, four-toothed For two-toothed fish "Diodon holocanthus "
We have Diodon liturosus,
Diodon holocanthus "Arothron stellatus"
For the 4 toothed Arothron stellatu
s,
Arothron reticularis "Arothron hispidus"
Arothron nigropunctatus In fact, many kinds Dear children Do you think we all look alike? "Diodon holocanthus "
In fact, in the waters near Taiwan I have a very special friend I'll introduce to you soon The most special one in our aquarium is Balistoides conspicillum it has a very beautiful appearance black color "Balistoides conspicillum"
It has white spots on its body it's also called clown cannonball Everyone come to the aquarium can see it That's r
ight My good friend is
Balistoides conspicillum It appears in the waters near Taiwan its meat is highly poisonous So please don't catch and eat them We look forward the most is the caretakers to feed us Not only can be full they also play with us so happy Wanna know what we all like to eat? We eat pufferfishes But everyone must not know What do pufferfish usually eat Those pufferfishes they are highly toxic "Balistoides conspicillum"
because they usually eat some poisonous starfish, etc these th
ings in the wild But in the aquarium "Diodon holocanthus "
we wouldn't feed them poisonous starfish We feed them some crustaceans like the clams we usually eat and crabs These hard crustaceans is edible for the pufferfish So pufferfish in the wild are poisonous because they like to eat poisonous starfish So what do pufferfish eat in aquarium? To become so healthy? In aquarium We mainly feed the following let's introduce them one by one This is a clam "Clams"
This is common to see It's the ones w
e eat For the clams we won't remove the shell because pufferfish itself has very hard teeth it can bite through the shell After it break the shell it eats the meat inside then spit out the shell cracks Just like we eating sunflower seeds so we won't help it remove the shell "Euphausia superba"
Next, this is Euphausia superba Euphausia superba we mainly give some smaller pufferfish Some pufferfish have smaller mouths so we will prepare some shrimps let it eat directly because if we feed clams It
can't break the shell with his tooth so we will feed the shrimps Next up this is Scomber For Scomber "Scomber"
It's the canned food we eat The kind you often eat with tomato sauce We use this the most it is rich in nutritional value It has high nutritional value so we mainly focus on this The others are mainly used as additions to make its bait more diverse Next Skipjack tuna It is what we usually eat it's the sprinkled on takoyaki balls "Skipjack tuna"
Bonito flakes are mainly made of it Skipja
ck tuna has a characteristic It has a strong fishy smell its flesh is dark red in color You'll find its blood content relatively rich For some carnivorous fish shark or grouper they will especially like to eat this Pufferfish also like to eat it Next is Pacific Saury it is usually what we eat at barbecue Pacific Saury has a relatively high oil content when we barbecue "Saury"
you will find it drip a lot of grease so we don't feed too much Because if you feed saury too much they will get fatter T
he food is too oily, they eat more fat keeps accumulating they will have fatty liver like humans It's not good for them Next we have Jack Mackerel Jack Mackerel has a feature "Jack Mackerel"
that is, on the tail has hard scales we call it Hard tail because of this characteristic For the last This is Argentinian squid very common in night markets you always see one there they grill or deep fried it It's the same kind The production of squid is large and the source of import is stable We need it e
very day makes it good food for them "Argentine squid"
It is less likely to run out of stock For a larger animal like a whale or a big shark We just feed it the whole one the entire one they can eat it For ones with smaller mouths we'll cut it into small pieces cut as small as possible make it bite size Because if you feed the whole fish they can't eat it clean They will only eat the stomach Because they have been raised by us they became picky eaters Head and tail have less meat they will not e
at it clean They are mainly picky belly to eat The uneaten part will stink if soaked for a long time the water quality will go bad The head and tail in the water is also not good for looking Everyone would think why do we have dead fish in the tank Therefore we will cut off the head and tail keep the middle section cut it into chunks We won't remove the viscera we just cut it smaller We try to maintain the original appearance of a whole fish The most nutritious part is the belly if you wash it t
oo clean many nutrients will be washed away we just cut it small try to let it eat in one bite Don't let much residual remain in water Delicious Look at each of them is round and fat Are they big eaters? In terms of food intake each type is different Yes, they come in different sizes The bigger the body, the more it eats We usually observe while feeding Obvious difference is between seasons The water temperature is low in winter they are less active with the water temperature is low they don't w
ant to move they eat less In summer, the water temp is higher they will eat more winter and summer we'll make little adjustments Usually when we feed we observe how aggressive they are to see if it's full If it is full they don't eat much not eager to eat just like us We eat slower when we're full "Diodon eydouxii"
There are so many types of pufferfish The appearances are different "Balistoides conspicillum"
How do they give birth? They come in so many different varieties Some do external fertil
ization less internal fertilization more are external fertilization Because they're not like sharks their reproductive organs is exposed on the outside of the body so they will have internal fertilization "Diodon holocanthus"
Did you guys see it today? The different sizes and types of it But you know how to tell if it's a boy or a girl? "Arothron manilensis"
Generally speaking as I mentioned the shark's sex organs are exposed So for stingrays and sharks We can tell by the naked eye to see it is
a female or male But we can't do that with pufferfish because of its sex organs is inside its body hard to see by the naked eye Big eyes with round body likes to hang out with friends Blow up with spikes when angry Even though it looks healthy but Pufferfish are just like human also get sick What common diseases do they have? Common diseases are Crytocaryon Crytocaryon is very a common disease in aquarium It's easy to tell by the eyes "Diodon holocanthus "
Its eyes will start to get foggy start
to grow white dots That means the parasite's on it When we take care of them every day "Diodon eydouxii"
we also observe If I see it with foggy eyes or odd swimming movement like swim sideways or backwards that indicates parasite's on it Other way to tell is by its appetite we feed them every day we see their aggressiveness That is if it eat a lot before but today it hides in meal time We knew something's wrong The key is to observe its behavior to judge whether it is sick So if you see us not e
ating move slowly and looks lazy Maybe it's because I'm not feeling well How should we treat sick pufferfish? For that we'll find a way to get it out bring it to the backcourt in quarantine barrels for checking we will ask a veterinarian to prescribe some medicines for parasites or add some antibiotics in the bait If it eats let it eat as much as it wants If it's already serious we'll try to use injections Just like us, use injections increase its antibodies to treat it We'll put it back when he
aled with everyone When we're sick they mix medicine with food we can eat delicious food also cure our diseases When it is not angry pufferfish looks very cute How toxic are they? Why can it be ranked in top ten most poisonous animals? pufferfish itself is highly poisonous Toxicity is about cyanide 1200 times Sometimes when it is releasing the toxic to kill the emeny it accidentally poison itself and died from it Translation: Studio886
