Teleostei (teleosts) > Gobiiformes (Gobies) > Eleotridae (Bully sleepers)
Etymology: Gobiomorphus: Latin, gobius = gudgeon + Greek, morphe = shape (Ref. 45335).
Eponymy: Krefft does not explain the eponym, but it probably honours James Charles Cox (1834– 1912), who also collected a snake that Krefft described in a companion paper. [...] (Ref. 128868), visit book page.

Biology     Glossary (e.g. epibenthic)

Populations appear more abundant in southern rivers, in flowing areas, including rapids (Ref. 2906, 44894). Adults are not found in lower reaches but individuals range upstream into areas of altitudes up to 700 m (Ref. 2906). Rarely found near to the sea (Ref. 44894). Individuals have been observed climbing dam walls using their pectorals, out of direct water flow (Ref. 2906). Adults feed on aquatic insects and mosquitofish. Juveniles generally found closer to the sea. During upstream migration these fish are capable of climbing waterfalls and steep dams. The female lays eggs on rocky surfaces and the male guards and fans the nest until hatching several days later (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00286 - 0.01269), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
