December 29, 2010 : Reef Squid
The Caribbean Reef Squid (Sepioteuthis sepioidea), also known as just the Reef Squid, is a small (20 cm) torpedo-shaped squid with fins that extend nearly the entire length of the body and undulate rapidly as it swims. The squid has recently become notable when it was discovered that it could fly out of the water; a discovery which finally led to identification of six species of flying squid.
The Caribbean Reef Squid is found throughout the Caribbean Sea as well as off the coast of Florida, commonly in small schools of 4-30 in the shallows associated with reefs. The 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 0.2-1 meters below the surface on or under vegetation. Young small squid typically congregate in shallow turtle grass near islands and remain several centimeters to two meters from the surface to avoid bird predators. Adults venture out into open water and can be found in depths up to 100 m. When mating, adults are found near coral reefs in depths of 1.5-8 m. The Caribbean Reef Squid is the only squid species commonly sighted by divers over inshore reefs in the Florida, Bahamas and Caribbean region.
