The eight arm-tip light organs of Vampyroteuthis

This value is close to the [P.sub.50] of 0.47 to 0.55 kPa evaluated for the cold-water vampire squid Vampyroteuthis

Included in these analysis were Vampyroteuthis

Iteroparity has been also documented in Vampyroteuthis

Lower beak rostral lengths (LRL) or hood lengths (HL; Vampyroteuthis
