noun
grey sharpnose shark
A species of requiem shark (Rhizoprionodon oligolinx) found in the Indo-Pacific. The name literally means 'anglerfish shark', likely from its appearance.
水族館でアンコウザメを見た。
I saw a grey sharpnose shark at the aquarium.
Compound of 鮟鱇 (ankō, 'anglerfish') + 鮫 (same, 'shark'). The exact reason for the name is uncertain, but it may refer to a perceived resemblance to an anglerfish.
