توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

Broad disc is greater in length than width; a relatively smooth dorsal surface except for a single row of thorns around the eyes and extending along the back and tail; a long, pointed snout with a rounded tip; small, rounded, pebble-like teeth; a first dorsal fin that originates closer to the pelvic fin base than to the caudal fin origin; a thick tail and a moderately large caudal fin without a distinct lower lobe.

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Found on sand or mud bottoms of bays, seagrass beds, estuaries, and near rocky reefs. Nomadic and gregarious. Found singly or in aggregations (Ref. 12951). Burrows in sand during the day, feeds on crabs, worms, clams and small fishes at night (Ref. 12951). Ovoviviparous, with 6 to 28 pups in a litter (Ref. 48844). Females mature by 7 years at 87-99 cm TL; males reaches 91-110 cm TL; birth size at 20-24 cm TL (Ref. 114953). Etymology: The genus comes from the Greek word rhine, meaning shark, and the Latin word batis, meaning ray, in reference to its body form being intermediate between that of a shark and a ray. The species name comes Latin, meaning produced, in reference to its pointed snout (Ref. 48844).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Adults of both sexes congregate during the breeding season in shallow bays and estuaries and likewise leave when the pupping season is over after mating (Ref. 48844). Gestation lasts for about 12 months (Ref. 48844).
