The blue ringed octopusThe blue ringed octopus is not a very big creature but it is very dangerous.
These octopuses are found all around the coast of Australia. They often lie in rock pools close to shore.
The blue ringed octopus is usually a dull colour but it shows its bright blue rings when it is in danger. If it is taken out of the water by someone, it is able to bite him and poison him.
If this creature bites someone, he will feel numbness (麻木) around the mouth, face and neck, Puffer Fish
Puffer Fish are found in all Australian seas. They are very easy to catch but must not be eaten because their flesh contains a poison.
Anyone who does eat the flesh can become sick very quickly. They may even stop breathing.
The Blue BottleThe Blue Bottle is found in most Australian waters. Blue Bottles float lightly on the surface of the water but their tentacles(触角)can be as long as 10 meters.
Blue Bottles are much less dangerous than some other jellyfish, but they can give a swimmer a bad sting(刺) if the swimmer accidentally touches them.
StingraysThere are many different kinds of stingrays in Australian waters. They usually swim and feed on the bottom of the sea. Accidents can happen if people stand on them or try to pick them up.

“If they get 50 to a lifelike but controlled environment, people can 51 learn to handle the 52 thing,” Redfern said.
