(total): 18-19. Trunk rings 11; tail rings 37; subdorsal spines 3/0,1,0; spine above eye of moderate size, length about pupil-diameter, slightly angled back; moderately large and recurving lateral head spine; long, forward-directed nape spine; nose profile straight; coronet moderately high, with spines on corners, posterior 3 largest and directed backward; 3 spines of moderate size on shoulder ring, uppermost and central spines at end of pectoral-fin base, lowermost ventrally; superior trunk ridge with spines of small to moderate size on rings 1, 4, 7 and 11, extended by long dermal flaps at spine tips in holotype; superior tail ridge similar to superior trunk ridge, with enlarged spines at regular intervals, becoming progressively smaller posteriorly (Ref. 42735).

Eastern Indian Ocean: known only from Monte Bello Islands and Exmouth Gulf, Western Australia. International trade is monitored through a licensing system (CITES II, since 5.15.04).
Found on the continental shelf (Ref. 75154). Holotype caught at the surface, clinging to Sargassum fragment (Ref. 42735). Maximum length is based on a straight-line length measurement from upper surface (ignoring spines) of first trunk ring, to tip of tail (Ref. 42735). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00162 - 0.01126), b=3.00 (2.78 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
