Etymology: Rhinoptera: Greek, rhinos = nose + Greek,pteron = fin, wing (Ref. 45335).
Eponymy: Franz Steindachner (1834–1919) was an Austrian zoologist who specialised in herpetology and ichthyology. [...] (Ref. 128868), visit book page.

Maturity: Lm 71.0, range 65 - ? cm
Max length : 91.6 cm WD 雄鱼/尚未辨别雌雄; (Ref. 116975)
Adults are found over soft bottoms, near rocky or coral reefs; also near reef drop-offs (Ref. 12951). They occasionally swim near the surface and may jump out of the water. Often in schools, sometimes associated with Aetobatus narinari, the spotted eagle ray (Ref. 12951). Adults feed on benthic crustaceans and mollusks. Ovoviviparous (Ref. 50449).
发现在软质底部上了, 在岩礁或珊瑚礁的附近; 也在礁海峭壁的附近.(参考文献 12951) 偶然地接近水表面而且可能离开水面跳跃。 常形成鱼群, 有时伴随着 Aetobatus narinari ，有斑点的鹰 .(参考文献 12951) 吃底栖的甲壳动物与软件动物。 卵胎生的.(参考文献 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).東太平洋: 加州灣到哥斯大黎加與加拉巴哥群島。 可能出現其他地方。

Phylogenetic diversity index (Ref.
82804): PD
50 = 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.

营养阶层 (Ref.
69278): 3.6 ±0.50 se; based on food items.
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
