deskripsi pendek Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)): 7-8; Sirip dubur lunak: 8. Pink-white. No eyes (vestigial eye tissues under skin). No pelvic fins. Usually 8 anal rays; 9-11 branched caudal rays.

Adults inhabit subterranean waters of quite small cave streams. Preferred habitat in these caves is chert rubble though individuals are also found in areas of silt-sand substrates. Stomachs examined contained copepods which constituted about 70-90% by volume with the balance being primarily small salamanders, crayfish, isopods, amphipods and young of their own species (Ref. 34868). Eggs are carried in gill chambers of females (Ref. 205). Threatened by overfishing (Ref. 10172).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6338 [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): 3.5 ±0.54 se; based on food items.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (K=0.3; Fec=25).

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