A rare pelagic cephalopod Ocythoe tuberculata (Octopoda: Argonautoidea): The record fecundity for octopoda and new data on morphometry [Nadir rastlanan bir pelajik ahtapot Ocythoe tuberculata (Octopoda: Argonautoidea): Ahtapotlari{dotless}n yumurta verimliligi ve morfometrisi üzerine yeni kayi{dotless}tlar]

Two adult female of Ocythoe tuberculata were caught in April 2002 (Mantle length, ML=285 mm) and in May 2003 (ML= 335 mm) in Izmir Bay, Aegean Sea the second one being the biggest individual ever found in all oceans as well as it had the highest known fecundity for the entire order Octopoda - around one million. Relations between mantle length (ML) to total weight (TW) was calculated as TW=0.0061*ML2.231, and to lower hood length (LHL) was as ML= 18.85*LHL-31.633. For this species relation between mantle length body weight and beak measurements were calculated for the first time using our unpublished and literature data. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.
