Remark |
: |
The mantle is muscular but generally thin. Dactylus often tabular clubs with quadriserial sucker but the carpal region is greatly expanded and carries numerous small suckers in many series. Arm suckers biserial. Fins short, terminal, with free anterior lobes. Simple, straight funnel-locking cartilage. Buccal connectives attach to the ventral margins of ventral arms. Light organs known only on eyes, where a single ventral light organ may be present. Little is known about the biology of brachioteuthid squids although aggregations near the ocean floor, at depth of about 800 m, have been observed from submersibles. Occurs from the surface to 3 000 m (Ref. 104052). |
