Perciformes/Uranoscopoidei (Sand dwellers) >
Ammodytidae (Sand lances)
Etymology: Ammodytoides: Greek, ammos = sand + Greek, dytes = anyone that likes immersions, diving (Ref. 45335).
Eponymy: Master John Rennie of Grahamstown, South Africa, discovered three specimens of this fish “found on the beach after an onset of cold water”. We assume the use of the term ‘Master’ implies that John was a boy when he made this discovery. (Ref. 128868), visit book page.
