IMIS

Siphonophores were sampled using stratified mesh nets during both day- and nighttime in Sagami Bay, off southeastern Japan during a 9-day period in March 2006. The samples were collected at 50-m intervals spanning from 1,000 m depth to surface. Fifty-eight species and 11 eudoxid forms of unknown parentage were collected, of which 5 represent first-time records from Japanese waters. The siphonophore communities could be related to the different water masses in the Bay.
