Description and Biology of a New Species of Pelagic Penaeid Shrimp, Bentheogennema Burkenroadi from the Northeastern Pacific.

摘要

The new species of pelagic penaeid shrimp lacks the richly plumose arthobranch described for the genus and has a single pair of terminal spines on the telson. It is found mainly in transitional water of the North Pacific between 500 and 1,000 m by day 150 and 1,000 m at night. Examination of testes and ovaries, and the structures of the petasma and thelycum, indicates a 4-5 mo spawning season and an equal male to female sex ratio. Generation time was estimated to be 2 yr.
