There are around 300 species of octopus, usually located in tropical and temperate ocean waters, like coral reefs. Octopuses have two eyes in a globe-shaped head which is called a mantle off which protrude eight long limbs called tentacles which have two rows of sucker senses. Octopuses can squeeze into small spaces because they don't have a skeleton inside of them.
An octopus has a hard beak, like a parrot beak, which they use to break into and eat their pray like crabs and shellfish. Octopus have three hearts. Two branchial hearts pump blood through each of the two gills, while the third is a systemic hearts that pumps blood through the body. The largest octopus is believed to be the giant Pacific octopus, which weigh about 15 kg, and has an arm span up to 14 feet. An octopus's main defense against predators such as sharks is to hide and camouflage itself by using there skin cells to change its color. It can also be used to talk with or warn other octopuses near bye. Another defense is to make a fast escape. Octopuses can eject a thick, blackish ink in a large cloud to distract the predator while the octopus uses a jet propulsion system to quickly swim away headfirst, with arms trailing behind the octopus. Octopuses have very good eyesight and an excellent sense of touch. Ashleigh
