- "I caught a puffer fish! Ouch!"
An information board in the aquarium will provide information about this fish.
"As expected, all puffer fish are covered in spines. While related to the blowfish, they are not poisonous. Exaggerated claims about the fish say they have 1,000 spines; the true number is between 300 and 400. When threatened, they suck in water and air to puff themselves up in order to intimidate enemies."
In real life
The Oblong Blow Fish can be found in Japan, Indonesia, Australia, South Africa, and Madagascar. Their diet consists mostly of algae, mollusks, invertebrates and sometimes crustaceans. It can grow up to 40cm, and can also change color over time. This helps them to camouflage. A very dark color may be a sign of stress or illness.
Like all pufferfish, they are not fast swimmers as they mainly use their pectoral fins for propulsion, but they are very maneuverable and able to hover, swim backwards, and change direction much more quickly than most other types of fish. As a result, they are rarely found in open water and prefer to stay relatively close to the sea bed. In the event of danger, the fish inflates itself by filling its extremely elastic stomach with water (or air when outside of the water) until the fish is almost spherical. Its main defense, however, is the neurotoxin contained in its internal organs. The toxin is called tetrodotoxin, and is about 1200 times deadlier than cyanide. The pufferfish does not create the poison itself; rather it is generated by bacteria within the fish.
