Distribution

Common and widespread, mostly in tropical and subtropical seas, and found throughout Australia. The Spearfish Remora usually hitches a ride attached to sharks, or in the gill chambers of billfishes and swordfishes. Like their hosts, the remora is epipelagic from surface waters to depths of 200 metres.

Features

Meristic features:
Dorsal-fin rays: 27-34
Anal-fin rays: 25-34
Cephalic sucking disc: 14-17 transverse lamellae
Gill rakers: Fewer than 21 (first arch)

Conservation

IUCN: Least Concern
Australia; Not listed

Similar Species

Most often confused with Remora albescens which has a longer disc reaching the pectoral-fin tips, and the head longer than the length of the dorsal-fin base.
