Engraulicypris howesi

biology_ecology

Biology. Very little is known of the biology of this species. Individuals appear to favour turbid, rocky, river regions where they can gather in pockets of recirculating currents. The holotype and some paratypes were collected in the shallow, turbid Olushandja Dam in the Namibian upper reaches of the system. They feed on drifting invertebrate larvae and adults and plankton.

etymology

Etymology. This species is named in honour of Gordon John Howes (1938 - 2013), whose studies of the osteology of the Danioninae (Howes 1980, 1984) laid the foundations of their modern classification. The epithet is a genitive noun.
