The Caribbean reef squid (Sepioteuthis sepioidea) is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of the body, approximately 20 centimetres (8 in) in length. The species is found throughout the Caribbean Sea, as well as off the coast of Florida, commonly in small schools of four to thirty individuals in the shallows associated with reefs. The habitat of the reef squid changes according to its stage of life and size. New hatchlings tend to reside close to the shore, in areas from 0.2 to 1 metre (1 to 3 ft) below the surface, on or under vegetation.
