Full Answer

Octopuses are eight-armed cephalopods within the phylum Mollusca. Most species are bottom-dwelling animals and use their arms to crawl along the ocean's floor. When threatened, an octopus is capable of spewing a jet of water through its siphon to quickly escape danger. An inky substance also is ejected from the octopus to blind and disorient predators.

  • Q:

    What are some characteristics of sharks?

    A:

    Sharks belong to the fish family, and are characterized by having skeletons that are made from cartilage rather than bone, a series of five to seven gill slits located on both sides of their body for respiration purposes, multiple rows of teeth for feeding which regrow after they have become loose or have fallen out and skin that is composed of a series of scales. Sharks have withstood the test of time; the species has populated Earth for more than 400 million years without exhibiting any drastic evolutionary changes. Although there are only a handful of fatalities related to sharks each year, they are highly predated upon by human beings with over 100 million hunted each year.
