背棘 (总数) : 4; 背的软条 (总数) : 8 - 9; 臀棘: 3; 臀鳍软条: 24 - 25. This species is distinguished from its congeners by the following set of character: head 3.2-3.7 in SL; body depth 2.7 in SL; head length 3.2-3.7 in SL; orbit diameter 1.9-2.7 in HL; caudal-peduncle depth 2.7-3.3 in HL; D IV, 8-9; A III, 24-25; pectoral rays 15; lateral-line scales 51-54; scales below the lateral line 10-11; circumpeduncular scales 11-12; gill rakers 23-25. Colour when alive mostly silvery, darker from mid-body to the lateral line and greenish above; fins translucent with a darker tail; when preserved light brown to silvery with darker dorsum and translucent fins; caudal fin darker. Further, mitochondrial DNA COI sequences show a divergence of at least 4% from all Atlantic congeners (Ref. 113730).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Observed to be schooling in the very shallow waters of the rocky Parcel pools (Ref. 113730).
