Pristiophoridae (Saw sharks)
Etymology: Pristiophorus: pristio-, presumably derived from prio (Gr.), to saw, but treated here as a noun (a saw); phorus, from phoreus (Gr.), bearer or carrier, referring to saw-like snout (note also that pristis is Greek for sawfish). (See ETYFish); lanae: In honor of “shark enthusiast” Lana Ebert (the senior author’s niece) on the occasion of her graduation from the University of San Francisco (her brother is similarly honored; see Rhinobatos austini, Rhinobatidae). (See ETYFish).

توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
This slender bodied five-gilled sawshark is distinguished from its congeners by the following combination of characters: a narrow, relatively long rostrum, with a pre-oral length 27.5-30.6% TL; pre-barbel length 51-55% of pre-oral length; rostral width at nostrils 4.8-6.1 times pre-orbital length. Barbels located closer to the mouth than to rostral tip. First dorsal fin originates posterior to free rear tip of pectoral fin; lateral dermal denticles are unicuspidate, mostly flat, and imbricated; color uniform dark brown above, lighter below; no bars, blotches or other distinctive markings (Ref. 94800).
Inhabits upper continental slopes in tropical waters (Ref. 94800).
