Etymology: Rhinoptera: Greek, rhinos = nose + Greek,pteron = fin, wing (Ref. 45335).

Issue
Considered valid in McEachran and Seret 1990 (Ref. 4441) but with a note that more recent authors consider it to be immature stages of R. marginata. Further study is needed to clarify problem (Ref. 4441). Tentatively valid in Last et al., 2016, for these differ subltly in their morphology (Ref. 114953:719).

Size / Gewicht / Alter

Maturity: L_m ? range ? - ? cm
Max length : 200 cm WD Männchen/unbestimmt; (Ref. 6678)

Found in tropical to warm temperate coastal waters, but absent from islands of western Pacific. Often forming large groups swimming near the surface and quite destructive of commercial oyster and clam beds. Feeds on bottom-living mollusks, crustaceans and fishes. Seldom marketed. Ovoviviparous, gestation period up to one year with 2-6 embryos produced.

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

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).

Estimates based on models

Preferred temperature (Ref. 115969): 17.1 - 21.7, mean 19.7 (based on 136 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00463 - 0.02844), b=2.98 (2.76 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.60 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=2).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (85 of 100).

Preiskategorie (Ref. 80766): Medium.
