Body shape (shape guide): short and / or deep.
Occur in upper margins of current-swept seaward drop-offs and ledges (Ref. 205, 48637). Current-prone and with rich invertebrate growth such as seawhips. Usually found at moderate depths over 20 meters and occuring in small loose groups (Ref. 48637). Benthopelagic (Ref. 58302). Form loose aggregations a few meters above the bottom where it feeds on zooplankton, particularly copepods. Oviparous (Ref. 205). Also taken by drive-in nets (Ref. 9770).
