Movement

"The octopus extend its arm toward the target by a wave like propagation of a bend that travels from the base of the arm toward the tip. Octopus move by jet propulsion sucking water into a muscular sac in the mantle cavity surrounding their bodies and quickly expelling it out a narrow siphon." (www.jneurosci.org)

Diet

"Octopus eat small crabs , scallops, plus some snails fish, turtles, crustaceans (like shimp)

and other octpus. They catch prey with their arms, then kill it by biting it with their tough beak, paralyzing the prey with a nerve poison, and softening the flesh." (www.enchangedlearning.com)

Reproduction

"The male octopus has a modified arm called the hectocotylus which about a meter long and holds rows of sperm. The female meticulously cares for eggs until they hatch forgoing food the entire time." (animals-howstuffworks.com)

Adaption

"Octopus can hide by squeezing into tiny crevices on the ocean floor. An Octopus will give itself an opportunity to escape by releasing a dark pigment along a jet stream of water." (animal/traits-octopus-survive.html)
