Taxonomy

''Dendrochirus'' was described as a genus in 1839 by the English naturalist William John Swainson. Swainson also named the genera ''Brachirus'' and ''Brachyrus'' in the same work but in later pages. In 1876

Pieter Bleeker Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia ...

revised the genus and chose ''Dendrochirus'' as the name for the genus. In 1882 Joseph Swain designated ''Pterois zebra'', described by Georges Cuvier from Mauritius in 1829, as the
