Squids are the primary sufferers of negative buoyancy in cephalopods. The negative buoyancy means that some squids, especially those whose habitat depths are rather shallow, have to actively regulate their vertical positions. This means that they must expend energy, often through jetting or undulations, in order to maintain the same depth.
The Caribbean reef squid is the only squid species commonly sighted by divers over inshore reefs in the Florida, Bahamas and Caribbean regions. They are also found around Brazilian reef habitats, due to a symbiotic relationship in which the squid protect juvenile fish from open-ocean predators.

Northern shortfin squid is a moderately-sized squid with females ranging from 20 to 30 centimetres (7.9 to 11.8 inches) in mantle length while males are generally smaller with mantle length ranging from 18 to 27 cm (7.1 to 10.6 in). [8] Northern shortfin squid has short tentacles with a long and narrow head which is connected to the long mantle.
Some egg beds can cover acres of the ocean floor. The eggs take 3–8 weeks to hatch with warmer water shortening the incubation time. Bat stars (Asterina miniatus) are the most prevalent predators of eggs. Fish do not eat them, although they will nip at eggs not covered by the capsule sheath. There is no brooding. Doryteuthis opalescens paralarva
