Japanese angel shark
A species of angel shark (Squatina japonica) found in Japanese waters. Typically written in katakana as カスザメ.
The Japanese angel shark is a type of flat shark that hides on the seafloor.
The name カスザメ likely derives from 糟 (kasu, 'dregs' or 'scum') and 鮫 (same, 'shark'), possibly referring to its appearance or habitat, but the exact origin is uncertain.
