Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 7 - 8; Vertebrae: 40 - 43. Anterior interorbital laterosensory pore well separated from the posterior nostril. Usually 2 pairs of pores below the lower jaw. Short gill rakers.

Facultative air-breathing in the genus (Ref. 126274); Lives on rocky shores of lakes. Bottom-dweller of upland lakes and associated streams, frequently under and around rocks on gravel substrates (Ref. 44894). Feeds on insects, small crustaceans and mollusks.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.43 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec<100).

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