Euprymna scolopes, also known as the Hawaiian bobtail squid, is a species of bobtail squid in the family Sepiolidae native to the central Pacific Ocean, where it occurs in shallow coastal waters off the Hawaiian Islands and Midway Island.
Margaret McFall-Ngai (born 1951) is an American animal physiologist and biochemist [1] best-known for her work related to the symbiotic relationship between Hawaiian bobtail squid, Euprymna scolopes and bioluminescent bacteria, Vibrio fischeri. Her research helped expand the microbiology field, primarily focused on pathogenicity and ...
Sagittal section of the large eye-like light-producing organ of Hawaiian bobtail squid, Euprymna scolopes. The organ houses symbiotic Aliivibrio fischeri bacteria. In the Hawaiian bobtail squid (Euprymna scolopes) light is produced in a large and complex two-lobed light organ inside the squid's mantle cavity. At the top of the organ (dorsal ...
Bobtail squid (order Sepiolida) [1] are a group of cephalopods closely related to cuttlefish. Bobtail squid tend to have a rounder mantle than cuttlefish and have no cuttlebone . They have eight suckered arms and two tentacles and are generally quite small (typical male mantle length being between 1 and 8 cm (0.39 and 3.15 in)).
Euprymna is a genus of bobtail squid comprising a number of species. [1] [2] ... Euprymna scolopes (Berry, 1913), Hawaiian bobtail squid; Euprymna schneehageni ...
A. fischeri have been most studied as symbionts of marine animals, including squids in the genus Euprymna and Sepiola, where A. fischeri can be found in the squids' light organs. [14] This relationship has been best characterized in the Hawaiian bobtail squid (Euprymna scolopes).

The symbiotic relationship between the Hawaiian bobtail squid Euprymna scolopes and the marine gram-negative bacterium Aliivibrio fischeri has been well studied. The two organisms exhibit a mutualistic relationship in which bioluminescence produced by A. fischeri helps to attract prey to the squid host, which provides nutrient-rich tissues and ...
