Etymology: Ogilbia: Taken from Ogilby, 1887-1915, icthiologist and zoologist (Ref. 45335); nigromarginata: Named for the black margins of its vertical fins.
Eponymy: James Douglas Ogilby (1853–1925) was an Irish-born Australian ichthyologist and taxonomist, son of the famous zoologist William Ogilby (below). [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 67 - 75; Anal soft rays: 50 - 57; Vertebrae: 41 - 44. This species is characterized by the following: vertebrae 11-12 + 29-33 = 41-44, dorsal fin rays 67-75, anal fin rays 50-57; outer pseudoclasper is broad, distally much expanded; inner pseudoclasper large, with two elongate branches pointing outwards, penis with abrupt change from thick base to thin tip; opercular spine with single, sharp tip, broad scale patch on cheeks with 6-8 vertical scale rows; otolith compressed, length: height ratio 2.1-2.2; vertical fins with black margins; head profile high (Ref. 57883).

Lives in rocky habitats. A 72 mm SL female collected was found to contain eggs 0.5 mm in diameter and a 75 mm female with eggs 0.8 mm in diameter (Ref. 57883).

Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 28.6, mean 25.1 °C (based on 205 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
