Bioluminescence in the deep-sea cirrate
octopod Stauroteuthis syrtensis Verrill (Mollusca: Cephalopoda).
Some histioteuthids have been observed swimming with their arms, like medusae and cirrate octopods (Voss et al., 1998; see below).
A similar pattern was observed for the cirrate octopod Opisthoteuthis californiana (Seibel et al., 1998).
Cirrate octopods with associate deep-sea organisms: new biological data based on deep benthic photographs (Cephalopoda).
Aspects of the functional morphology of cirrate octopods: locomotion and feeding.
Videotapes filmed from submersibles have documented the behavior of deep-sea squids (Moiseev, 1991; Vecchione and Roper, 1991; Roper and Vecchione, 1997) and cirrate
octopods (Vecchione and Young, 1997; Villanueva et al., 1997).
The emission of blue-green bioluminescence ([[lambda].sub.max] = 470 nm) was observed from sucker-like structures arranged along the length of the arms of the cirrate octopod Stauroteuthis syrtensis.
In the case of cirrate octopods, bioluminescence has been suggested but never confirmed (Aldred et al., 1982, 1984; Vecchione, 1987).
This study provides the first description of bioluminescence in the cirrate octopod Stauroteuthis syrtensis.
Like the suckers of other cirrate octopods, the photophores of S.
