Short description Morphology | Morphometrics

Anal soft rays : 7. Exoglossum laurae is distinguished by the following characters: central body plate with fleshy lobe to either side on lower jaw; body chubby and barely compressed; deep caudal peduncle; dorsal fin origin over pelvic fin origin; snout round, mouth sub-terminal; thick upper lip thinner at middle; premaxillary frenum present; usually a small barbel near corner of mouth; complete lateral line with 47-53 scales; 7 anal rays; pharyngeal teeth 1,4-4,1. Body color olive-gray above, silver green-purple side; fins clear to light olive or light red; and small individuals with dusky stripe along side and onto snout, black caudal spot (Ref. 86798 ).

Biology     Glossary (e.g. epibenthic)

Inhabits rocky pools and runs of creeks and small to medium rivers, often near vegetation or other cover. Males construct large circular or rectangular nests by piling pebbles carried in the mouth (Ref. 86798 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.9   ±0.4 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
