Teleostei (teleosts) >
Tetraodontiformes (Puffers and filefishes) >
Balistidae (Triggerfishes)
Etymology: Rhinecanthus: Greek, rhinos = nose + Greek, akantha = thorn (Ref. 45335).
Eponymy: Pablo Ruiz Picasso (1881–1973) was a Spanish painter and sculptor. The vivid patterns and colours of Rhinecanthus triggerfish have led to them being popularly known as picassofish. Not an eponym but reported by Forsskål as being a local Arabic name for the fish – ‘Azzazi’. (Ref. 128868), visit book page.
