Bathyphysa sibogae is a rare species of siphonophore in the family Rhizophysidae.[1] It is found at a depth of 500 to 2000 meters deep[2] in the Atlantic Ocean.[3]
Description
[edit | edit source]The longest specimen of B. sibogae was 72 cm in length, its pneumatophore 9 mm long and 4 mm wide. Porus is visible but without pigmentation. Siphons attain a length of 10-30 mm. In the 21st group, a 13 mm tentacle with tentilla at the base of the siphon is noticeable.[2]
The siphonophore hangs vertically in the water, stem below the pneumatophore and tentacles trailing behind. It does not swim by contraction of the ptera.[3]
The amphipod, Schizoscelus ornatus, is known to be associated with colonies.[3]
