Etymology: Urogymnus: Greek, oura = tail + Greek, gymnos = naked (Ref. 45335).
More on authors: Bloch & Schneider.

Issue
Urogymnus africanus and Urogymnus asperrimus are considered synonyms and both are originally described in the same work. There is uncertainty about which name has priority, and thus both names can be found as valid; the first reviser is not researched (Eschmeyer, 2014).

Краткое описание определительные ключи | морфология | морфометрия

Diagnosis: A heavily armored stingray lacking a venomous barb; young with large, flat denticles on upper surface, and large juveniles and adults with additional sharp conical thorns and small, pointed denticles (Ref. 5578).

Inhabits the continental shelf area (Ref. 2334), but capable of entering coastal lagoons (Ref. 81259). Found on sand and coral rubble areas near reefs (Ref. 9840), often in caves. Ovoviviparous (Ref. 50449). Due to its difficult handling, it is probably of limited commercial value (Ref. 9840). Its thorn can inflict a painful injury; caught commonly by demersal tangle net fisheries; utilized for its meat, skin (very high value) and cartilage (Ref.58048).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

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). Distinct pairing with embrace (Ref. 205). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 25.4 - 29.3, mean 28.5 (based on 2874 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.46 se; based on food items.

устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
