There are more than 150 species of octopus, ranging from the very small to the giant octopus, which
may reach 33ft (10m) in length. Most of them eat crabs, fish, crustaceans and smaller mollusks, which
they catch and tear apart with their suckered tentacles. An octopus’ mouth is shaped like a parrot’s
beak, with two very strong jaws. In addition the octopus can inject venom or poison with its bite,
which enables it to disable prey that might fight back, such as crabs, more quickly. Octopses are very
intelligent, curious animals, with a highly developed nervous system and extremely good eyesight.
They propel themselves through the ocean by squirting water from the edge of their mantle. They are opportunistic feeders , which means that they will tackle almost anything when they are hungry!
