Etymology: Danakilia: Ethiopia desert; for Thysvander Audenaerde (1968) it is a fish from northeast Africa; dinicolai: Named in memory of Ernesto Di Nicola, a member of the 2001 expedition to Lake Abaeded who died in a car accident while returning from the lake (Ref. 85754).

簡短描述

背棘 (總數) : 13 - 14; 背的軟條 (總數) : 9 - 11; 臀棘: 3; 臀鰭軟條: 7 - 8; 脊椎骨: 25 - 26. Diagnosis: Danakilia dinicolai differs from its congener, D. franchettii, in the possession of longer pectoral fins, 31.1-38.7% of standard length vs. 21.7-30.6%; outer row teeth in both oral jaws composed of stout tricuspids, considerably more robust and fewer in number than those of D. franchettii; lower pharyngeal bone relatively massive, longer than wide, length 30-32% of head length, vs. small, only slightly longer than wide, length 25-27% of head length in D. franchettii, with 40-48 teeth in posterior row, vs. 26-36 in D. franchettii (Ref. 85754).
Found in Lake Abaeded, a small oval depression in a volcanic crater; lake surface is about 30 m below sea level; sand from dunes along the eastern and southern rim is frequently blown into the lake; the lake is fed by many hot springs at surface level and underwater (Ref. 85754). The lakeshore is almost completely encircled by reeds, Phragmites australis, and stands of tamarisk, Tamarix aphylla, but is free of vegetation in the proximity of hot springs (Ref. 85754). Diet primarily consisting of algae grazed from the surface of plants and rocks; however, it is likely that this species is an opportunistic feeder, as individuals were caught on lines baited with grasshoppers (Ref. 85754). Large males guard pits over sand (Ref. 85754).
