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); acutus: Latin for sharp or pointed, probably referring to narrow, pointed snout. (See ETYFish).

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. A small shark with a long, narrow, snout, big eyes without notches, long labial furrows, and oblique-cusped teeth which may be smooth-edged or weakly serrated; 2nd dorsal fin small, low and behind larger anal fin; no interdorsal ridge (Ref. 5578). Grey or grey-brown above, white below (Ref. 5578). Dorsal and anal fins with dusky or blackish edges, fins slightly darker than back (Ref. 9997).

Found on continental shelves, often on sandy beaches and rarely in estuaries (Ref. 244). Reported to enter freshwater and recorded several times from Cambodia as far upstream as the Great Lake (Ref. 12693). Occurs near the surface in shallow waters (Ref. 12693). Feeds mainly on small pelagic and benthic bony fishes, also cephalopods and other invertebrates (Ref. 244). Viviparous (Ref. 50449). Utilized fresh and possibly dried salted for human consumption and for fishmeal (Ref. 9997). The 178 cm specimen recorded off Africa is possibly based on some other species (Ref. 9997).

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

Distinct pairing with embrace (Ref. 205). Viviparous, with a yolk-sac placenta; 2 to 8 in a litter (Ref. 9997), usually 2 to 5 after a gestation period of ~ 12 months; no seasonality in the reproductive cycle (Ref.58048). Size at birth between 25 and 39 cm.
