Etymology: Rhizoprionodon: rhiza (Gr.), root; prion (Gr.) saw; odon (Gr.), tooth, referring to teeth with serrated (saw-like) bases, or roots [replacement name for Rhizoprion Ogilby 1915, preoccupied by Rhizoprion Jourdan 1861 in mammals]. (See ETYFish);  oligolinx: Per Springer, Greek for “short furrow,” referring to short upper labial furrow. (See ETYFish).

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Position of anal fin origin well in front of second dorsal fin origin, long labial furrows, and short pectoral fins (Ref. 37816).

биология     глоссарий (например epibenthic)

A little known inshore and offshore shark found on continental and insular shelves (Ref. 244). Found to depths of at least 36 m (Ref. 9997). Probably feeds on fishes, cephalopods, and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Commonly caught by inshore demersal gillnet fisheries, especially off Java (Ref.58048). Utilized fresh and probably dried salted for human consumption (Ref. 244). Also used for fishmeal (Ref. 9997) and fins (Ref.58048). Minimum depth from Ref. 58018.

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки
