The octopus name comes from the Greek word Octarovoc, meaning eight legs and inhabits many regions of the ocean, especially the coral reefs.
There are 289 different species of octopus and they are characterized by their eight arms, not tentacles, as most people think they are called. Their arms have suction cups and are a type of muscular mechanism and they have entirely soft bodies with no internal skeleton.
They don't even have protective shell and the only part that is hard is the octopus's beak, similar to a parrot's beak. There is a very good reason why the octopus is soft and that is to enable him to squeeze into small spaces.
Octopuses have short life-span and some species for as little as six months. Larger species may live up to five years. However, reproduction is cause of death. Males can only live for a few months after mating and the female dies shortly after their eggs hatch, because they neglect to eat during the one month period spent taking care of their un-hatched eggs.
Octopusses have three hearts ~ two to pump blood through each of the two gills and the third to pump blood through the body. They are very intelligent creatures and have been known to solve very complex puzzles.
Some species can kill a human, but they will only do this if they feel that they are being threatened. The octopus can eject a black ink in a large cloud and some can inject poison to anyone threatening them.
