Urolophidae (Round rays)
Etymology: Urolophus: Greek, oura = tail + Greek, lophos = crest (Ref. 45335).
More on author: Whitley.
Environment: milieu / climate zone / depth range / distribution range
पारिस्थितिकी
समुद्री ड़िमरसल; गहराई सीमा 45 - 300 m (Ref. 9863), usually 100 - 160 m (Ref. 9863). Temperate; 26°S - 38°S, 149°E - 154°E
Southwest Pacific: Australia, from Queensland to New South Wales. Possibly hybridizes with the largely allopatric banded stingaree Urolophus cruciatus (a more southern species), and perhaps one of the few known cases of chondrichthyan hybridization.

Estimates based on models
Preferred temperature (Ref.
123201): 14.1 - 21, mean 18.2 °C (based on 11 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
लौटाव (Ref.
120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).
Fishing Vulnerability (Ref.
