Short description आकृति विज्ञान | मौरफोमैटरिक्स

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).

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).

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.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).

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