First Record of a False Cat Shark, Pseudotriakis microdon (Carcharhiniformes: Pseudotriakidae) from Sagami Bay

Abstract

A false cat shark, Pseudotriakis microdon de Brito Capello, 1868 (Carcharhiniformes: Pseudotriakidae) was first recorded from Sagami Bay on the basis of an immature male of 1,609 mm in total length. The specimen was collected at a depth of 330 m on March 23, 2013. This shallower depth record in Japan suggests that the shark migrates to shallower waters during early spring under low water temperature. The measurements and counts are given in detail.
