单词 panchax
释义

panchaxn.

Brit. /ˈpantʃaks/, U.S. /ˈpænˌtʃæks/
Inflections: Plural unchanged, (rare) panchaxes.
Origin: A borrowing from Latin. Etymon: Latin panchax.
Etymology: < scientific Latin panchax, specific name (see quot. 1822), later also a former genus name ( Cuvier and A. Valenciennes Hist. nat. des poissons (1846) XVIII. 380), of uncertain origin; perhaps < ancient Greek πάγχυ wholly, entirely (ultimately < πάς all (see pan- comb. form), although the suffixation is unclear); apparently so called on account of the entirety of the tail fin (compare quot. 1822).
Originally: a fish of the former genus Panchax of small Old World tropical killifishes (family Poeciliidae); (in form Panchax) the genus itself. In later use more widely: any of numerous killifishes, esp. of the genus Aplocheilus, and including many popular aquarium species.Members of the former genus Panchax are now included in Aplocheilus.
