🐟 Physical Description

Dorsal soft rays (total): 10; Anal soft rays: 8; Vertebrae: 24 - 26. Horadandia atukorali differs from its congener H. brittani by having a more slender body (depth 24.6-29.8 % SL, vs. 27.7-31.9); dorsal profile of head slightly concave (vs. straight) behind level of eye; a greater eye diameter (37-41 % HL, vs. 27-37); origin of dorsal fin slightly posterior to (vs. distinctly behind) origin of pelvic fin; pelvic fin reaching beyond anal-fin origin (vs. just reaching anal-fin origin); origin of dorsal fin located halfway between snout tip and hypural notch (vs. closer to hypural notch); one (vs. none) lateral process on each side of kinethmoid; anterior end of kinethmoid narrow (vs. wide); palatine process of maxilla acute (vs. obtuse); and supraorbital length ~50 % of orbit diameter (vs. ~44 %) .: fusiform / normal.
