Cone snail



Cone snail
Cone snail is a venomous snail found in north Australia  and  east Africa  . It has toxins in it's harpoon . Though it moves slowly but it catch like a bullet . It spears it's harpoon it the prey and swallow it hole . It can paralyze a human and kill it .

Distribution and habitat

This genus is found in all tropical and subtropical seas from tidal waters to deeper areas, living on sand or among rocks or coral reefs. When living on sand, these snails will bury themselves with only the siphon protruding from the surface. Many tropical cone snails live in or near coral reefs. Some species are found under rocks in the lower intertidal and shallow subtidal zones.



Harpoon and venom


The tooth is hollow and barbed, and is attached to the tip of the radula in the radular sac, inside the snail's throat. When the snail detects a prey animal nearby, it extends a long flexible tube called a proboscis towards the prey. The radula tooth is loaded with venom from the poison bulb and, still attached to the radula, is fired from the proboscis into the prey by a powerful muscular contraction. The venom paralyzes small fish almost instantly.

SAVE ANIMALS
It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.

 THE END

THANK YOU
