چکیده

What is a bobtail squid? Euprymna scolopes (Figure 1) is a small sepiolid squid, or bobtail squid, occurring in the marine coastal environment of the Hawaiian archipelago. Whereas most other squid are always out and about, the bobtail squid buries itself in the sand during its daylight quiescent period. Then, at night, individuals of this species emerge from the sand to forage on prey, such as shrimp and worms, that are swimming in the water column. To camouflage themselves while swimming, these squid form a relationship with the luminous bacterium Vibrio fischeri. The light of their symbiotic microbial population is emitted out of the animal’s ventral surface, and mimics down-welling moonlight and starlight, so that the squid does not cast a shadow. In this way, potential predators on the sea floor cannot see the bobtail squid as easily.

Obtaining Hemocytes from the Hawaiian Bobtail Squid Euprymna scolopes and Observing their Adherence to Symbiotic and Non-Symbiotic Bacteria

Studies concerning the role of the immune system in mediating molecular signaling between beneficial bacteria and their hosts have, in recent years, made significant contributions to our understanding of the co-evolution of eukaryotes with their microbiota. The symbiotic association between the Hawaiian bobtail squid, Euprymna scolopes and the bioluminescent bacterium Vibrio fischeri has been u...

Leisingera sp. JC1, a Bacterial Isolate from Hawaiian Bobtail Squid Eggs, Produces Indigoidine and Differentially Inhibits Vibrios

Female members of many cephalopod species house a bacterial consortium in the accessory nidamental gland (ANG), part of the reproductive system. These bacteria are deposited into eggs that are then laid in the environment where they must develop unprotected from predation, pathogens, and fouling. In this study, we characterized the genome and secondary metabolite production of Leisingera sp. JC...

Identification and molecular characterization of a complement C3 molecule in a lophotrochozoan, the Hawaiian bobtail squid Euprymna scolopes.

Examination of the EST database of the light organ of the Hawaiian bobtail squid Euprymna scolopes revealed a sequence with similarity to complement C3. RACE yielded the full open reading frame of this protein. Analysis of the resultant sequence revealed that Es-C3 (E. scolopes-C3) has conserved residues and domains known to be critical for C3 function. The gene encoding C3 was expressed in all...
