Teleostei (teleosts) > Gonorynchiformes (Milkfishes) > Kneriidae (Shellears)
Etymology: Cromeria: Perhaps related to the prehistoric Stone Age in eastern England; for the stone implements found in Cromer but needs more data.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 10; Anal soft rays: 7 - 8; Vertebrae: 40 - 43. Diagnosis: pelvic fin origin at level of anterior base of dorsal fin; preorbital stripe present; caudal peduncle depth 6.9-11% of SL; dorsal precaudal fin fold not reaching base of dorsal fin; 8-9 pectoral fin rays; 7 pelvic fin rays; 2 supernumerary rays in anal fin; 8 dorsal fin pterygiophores; 9+9 principal caudal fin rays; cephalic lateral line canals and supraorbital bone present; parasphenoid wide, with foramina for internal carotid arteries; neural spine of 2nd vertebra short and wide, only the length of its vertebral centrum and different from subsequent neural spines (Ref. 57474).

Maximum TL was recorded at 4.1 cm (Ref. 3566). Occurs on several substrates from fine mud to rough gravel and plant material; almost never buries into the substrate (Ref. 57474). Feeds on plankton (Ref. 57474, 91322) and phytoplankton (Ref. 91322). Reproduction likely takes place during the rainy season (August to September) (Ref. 57474) at high water levels in floodplains, brooks or rice fields (Ref. 91276, 91322).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [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).

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