Centrolophidae (Medusafishes)
Etymology: Schedophilus: Name from Greek words 'phylos' (Φίλος), t) meaning 'one who likes' and "s 'shedia' (Σχεδία) which means raft; literally means 'the one who likes rafts'. This probably refers to the lifestyle ot the juveniles of this genus (Michail Ragousis, mar10091@marine.aegean.gr, pers. Comm. 01/16) which are epipelagic and associate with floating jellyfish.
Eponymy: Charles Vélain (1845–1925) was a French geographer and geologist, and particularly an expert on volcanism. He took part in a mission to Saint Paul Island (1874) in the southern Indian Ocean, which is the type locality of this fish. (Ref. 128868), visit book page.
