whats the difference between an octopus and squid2007-11-24 23:43:31Answers:

Octopuses and squids 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.

Both octopuses and squids are related to snails and other molluscs. Unlike snails, octopuses no longer have any remnant of a shell. Squids possess a stiff structure known as a pen, that acts as a flexible backbone.

Both squids and octopuses have blue blood! Their blood is this colour because they use an oxygen-carrying molecule in their blood that contains copper.

Octopuses and squids have hard, parrot-like beaks. These are excellent for killing, and tearing pieces of flesh from their prey.

Octopuses live in dens on the sea floor. Squids live in the open oceans.

Octopuses use their eight sucker-lined arms to capture their prey and move about on the ocean floor. Squids have eight arms lined with suckers and two specialized tentacles that they use to reach out and capture prey.

Octopuses eat bottom-dwelling crustaceans. Squids eatfishes and shrimps. Some deepwater squids may be scavengers.

Octopuses pierce the shells of their prey, injecting poison that causes paralysis. They then release salivary enzymes, loosening the meat from the inner shell. Squids use their two specialized tentacles to quickly reach out and capture fishes. They tear off bits of flesh and scrape the meat into their mouths with their beaks.
