Vertical distribution, behavior, chemical composition and metabolism of Stauroteuthis syrtensis (Octopoda: Cirrata) in the northwest Atlantic
The cirrate octopod Stauroteuthis syrtensis is a mesopelagic species commonly collected in the North Atlantic. Individuals were observed at depths >600 m and typically within 100 m of the bottom in three ~900 m deep canyons indenting the southern edge of Georges Bank. When first sighted, most oct...
