Description
Hawaiian Bobtail Squid (Euprymna scolopes) eggs in late stage. The squid lay their eggs in clutches on the sea floor, where they take approximately three weeks to develop. Hawaiian bobtail squid form a symbiosis with the bioluminescent bacterium Vibrio fischeri. Once the squid hatch, V. fischeri from seawater colonize the light organ within hours. The light organ is part of the ink sac-hind gut complex and houses the symbionts. Hawaiian bobtail squid are nocturnal predators, remaining buried under the sand during the day and coming out to hunt for shrimp at night neat coral reefs. The squid have a light organ on their underside that houses a colony of glowing bacteria (V. fischeri). The squid uses this bacterial bioluminescence in a form of camouflage called counter-illumination, masking it's silhouette by matching moonlight and starlight; thus hiding from predators swimming below.
