Scientific Name
Bathypterois longipes

Common Name
Abyssal spiderfish

Biology
Solitary. Occurs in waters with a temperature range of 4.5-0.4?C (Ref. 3590). Uses its specialized fin rays (tripod) to elevate body into water column. Specialized sensory pectoral fins are spread facing anteriorly, probably to detect prey. Feeds on planktonic crustaceans. Synchronously hermaphroditic (Ref. 6688).
