検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 2; 背鰭 (合計) : 6; 肛門の骨: 0; 臀鰭: 15; 脊つい: 33 - 35. Like N. robertsi and N. palawanensis, has a large second ctenactinium that is bifid distally, but distinguished from those species by having a bone larger and more distinctly claw-shaped, and extent of a bony projection and fleshy profile on the ventral margin of the first ctenactinium that abuts the claw (Ref. 44355).
Body shape (shape guide): elongated.
Collected over a muddy bottom, in a slightly turbid irrigation ditch relatively near the sea (Ref. 44355). Fertilization is internal and eggs are attached to the substrate via adhesive filaments (Ref. 43413).
