Squids are fascinating creatures that reside in the ocean. Squid
have a large head, 8 arms with suckers, 2 longer feeding
tentacles, a beak, 2 large eyes, and 2 hearts. A squid’s skin
can flash up to 50 hypnotic patterns. Squids use changing body
color patterns to signal each other. The size of a squid can
vary from area to area. Some squids are just about 24 inches
long, while some can grow up to 40 feet in length. Squid’s body
shape and water-jet propulsion system makes it the fastest
swimmer of all animals without backbones. credit: Articulate
