The Caribbean reef squid is the only squid species commonly sighted by divers over inshore reefs in the Florida, Bahamas and Caribbean region. Cephalopods (squid, cuttlefish and octopus) are probably best known for their ability to change color and pattern for camouflage and communication. Not eaten by people or fished.The Caribbean reef squid population estimates to tens of thousands of individuals.They communicate through a variety of difficult signals by controlling pigments in their skin.They are semelparous.The female dies right after laying the eggs.The male can mate with many females in a short period of time before they die. During their life, S. sepiodea live in different spots in the water, depending at which stage of their life they are in. 275), usually 3 - 7 m (Ref.

Caribbean reef squid can even discriminate between recipients, sending one message using color patterns to a squid on their right, while they send another message to a squid on their left. A provolve clade famous for being one of the first two cephalopod provolve clades brought into existence, along with the Neuropus, and therefore also one of the first two invertebrate provolves as well.

Experimental support for squid ink acting as a conspecific alarm cue has recently been provided for Caribbean reef squid (Wood et al., 2008). They can be a green or a brown on their upper side, and are light colored on their under side for camouflage from predators swimming above or below them. A taxonomy of the movement possibilities for any species, within the constraints of its neural and skeletal systems, should be one of the foundations of the study of its behaviour. They are mostly seen underwater, though six reported species are known to be able to shoot out of the water for about 6 feet and fly up to 33 ft before reentering.
