Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 10; Raggi anali molli: 8; Vertebre: 24. Horadandia brittani can be diagnosed from its congener H. atukorali by the combination of the following characters: deeper body (depth 27.7-31.9 % SL, vs. 24.6-29.8); dorsal profile of head approximately straight (vs. concave) behind level of eye; lesser eye diameter (27-37 % HL, vs. 37-41); origin of dorsal fin distinctly behind (vs. slightly posterior to) origin of pelvic fin; pelvic fin just reaching (vs. reaching beyond) origin of anal fin; origin of dorsal fin located closer to hypural notch than to snout tip (vs. dorsal-fin origin located halfway between snout tip and hypural notch); a lateral process on side of kinethmoid absent (vs. present); palatine process of maxilla obtuse (vs. acute); and supraorbital length ~44 % eye diameter (vs. ~50 %) (Ref. 94541).
Inhabits coastal floodplain (Ref. 94541).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00390 - 0.02036), b=3.02 (2.82 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
