True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by jet propulsion, and largely locate their prey by sight. They are among the most intelligent of invert ...

Caribbean Reef Squid
The Caribbean reef squid (''Sepioteuthis sepioidea''), commonly called the reef squid, is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of the body, approximately in length. In 2001, marine biologist Silvia Maciá discovered that squid were able to propel themselves up out of the water about and fly approximately before re-entry; a discovery which led to the identification of six species of flying squid. Distribution and habitat The Caribbean reef squid is found throughout the Caribbean Sea as well as off the coast of Florida, commonly in small Shoaling and schooling, schools of four to thirty in the shallows associated with reefs. The Habitat (ecology), habitat of the Reef Squid changes according to the squid's stage of life and size. New hatchlings tend to reside close to the shore in areas from below the surface on or under vegetation. Young small squid typically congregate in shallow turtle grass near islands and remain ...
