4. Squids Info!
The Squid is an invertebrate (animal without a backbone) that swims in the oceans. This mollusk is closely related to the octopus. Squid can change the color of their skin to mimic their environment and hide from predators.
Squid are soft-bodied organisms. They are classifieds as Phylum: Mollusk, Class cephalopods. They move by squirting water from the mantle through the siphon, using a type of jet propulsion. When in danger, squid squirt a cloud of dark ink in order to confuse their attacker and allow the squid to escape. Squid reproduce by releasing eggs into the water. Some squid eggs are free-floating, others are attached to seaweed or to the ocean floor.

5. Anatomy: Squid range from 1 to 60 ft (0. 3 to 18 m) long
Anatomy: Squid range from 1 to 60 ft (0.3 to 18 m) long. The biggest squid is the Giant Squid (Architeuthis). Squid have a large mantle/head (with a large brain), eight arms with suckers, two longer feeding tentacles, a beak, a large head, two large eyes, and two hearts. Their large eyes are very similar in structure to people's eyes. They breathe using gills.
Diet: Squid eat fish, crustaceans (like shrimp), and other squid. These fast-moving carnivores (meat-eaters) catch prey with their two feeding tentacles, then hold the prey with the eight arms and bite it into small pieces using a parrot-like beak. The esophagus runs through the brain, so the food must be in small pieces before swallowing.
Predators: Many animals prey upon squid, including many sharks and other fish, some whales, squid, and people.
Classification: Kingdom Animalia, Phylum Mollusca, Class Cephalopoda, Order Teuthoidea, Families Loliginidae, Sepiolidae, and Architeuthidae.
