臀鰭軟條: 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).
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).
棲息於小溪及小型到中型河川的多岩石的水池與小支流, 時常在植物或其他的表面附近。 繁殖期的雄性建立大而圓形或矩形的巢用嘴巴堆砌小圓石。
