Etymology: Rhinoptera: Greek, rhinos = nose + Greek,pteron = fin, wing (Ref. 45335). More on author: Evermann.
Environment / Climate / Range
Marine; reef-associated; oceanodromous (Ref. 51243); depth range 0 - 30 m (Ref. 5227). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm 70.0, range 65 - ? cm
Max length : 90.0 cm WD male/unsexed; (Ref. 28023)
Eastern Pacific: Gulf of California to Costa Rica and the Galapagos Islands. Probably occurring elsewhere.
Found over soft bottoms, near rocky or coral reefs; also near reef drop-offs (Ref. 12951). Occasionally near the surface and may jump out of the water. Often in schools, sometimes associated with Aetobatus narinari, the spotted eagle ray (Ref. 12951). Feeds on benthic crustaceans and mollusks. Ovoviviparous (Ref. 50449).
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).

Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (46 of 100) .
