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. (Ref. 128868), visit book page.
