The transcription factors Apterous/Lhx2/9 play many pivotal roles in the development of protostomes and deuterostomes, most notably limb patterning, eye morphogenesis, and brain development. Full-length apterous/lhx2/9 homologs have been isolated from several invertebrate species, but hitherto not from a lophotrochozoan. Here, we report the isolation, characterization, and spatio-temporal expre...
The cloning of a Pax6 orthologue from the sepiolid squid Euprymna scolopes and its developmental expression pattern are described. The data are consistent with the presence of a single gene encoding a protein with highly conserved DNA-binding paired and homeodomains. A detailed expression analysis by in situ hybridization and immunodetection revealed Pax6 mRNA and protein with predominantly nuc...
Many cephalopods exhibit remarkable dermal iridescence, a component of their complex, dynamic camouflage and communication. In the species Euprymna scolopes, the light-organ iridescence is static and is due to reflectin protein-based platelets assembled into lamellar thin-film reflectors called iridosomes, contained within iridescent cells called iridocytes. Squid in the family Loliginidae appe...
This study reports the first description and molecular characterization of naturally occurring, non-bioluminescent strains of Vibrio fischeri. These 'dark' V. fischeri strains remained non-bioluminescent even after treatment with both autoinducer and aldehyde, substrate additions that typically maximize light production in dim strains of luminous bacteria. Surprisingly, the entire lux locus (ei...
Anthropogenic activity and its associated sounds have been shown to incur adverse effects on the behaviour physiology of a wide range aquatic taxa, from marine mammals fishes. Yet, little is known about how invertebrates detect respond anthropogenic sound. The hummingbird bobtail squid ( Euprymna berryi ) has short lifespan (< 6 months), grows sexual maturity around 90 days post hatching...
