Description

Harriotta avia is distinguished from its congeners ( Harriotta raleighana and Harriotta haeckeli ) by several characteristics, including elongated slender trunk, slim rod-like pelvic claspers, dorsal spin going beyond the dorsal fin's apex, and long thin snout up to 56% of its body diagonal length. [1] Its body color is mainly chocolate brownish if the skin is intact. This species maximum total length is around 107.5 cm for female specimens and 95.7 cm for male specimens. [1]

Distribution and habitat

It is suggested that Harriotta avia lives at a depth of 260–1278 m, although 400–1000 m might be a closer possibility. [1] [ why? ]
