The Hebrew, Latin and Greek that is translated in English as “reptiles” or “creeping things” or similar is translated as “those which crawl along upon their stomach” in San Mateo del Mar Huave, “those that crawl the way they travel” in Chichimeca-Jonaz, and “animals that crawl on the ground” in Lalana Chinantec. (Source: Viola Waterhouse in Notes on Translation August 1966, p. 86ff.)
In Nyamwezi it is translated as as vitundwa vya ku’yu’mba or “creatures that move.” (Source: Pioneer Bible Translators, project-specific translation notes in Paratext)

The Hebrew words zachal and remes literally mean “creeping [things]” or “crawling [things]”, which is the Hebrew way of referring to small unclean creatures, reptiles in particular. The Greek word herpeton is also a general word for reptile; it includes snakes and lizards. All of the Hebrew, Greek, and Latin words usually exclude fish.
The Hebrew words carry the connotation of uncleanness.
In languages which have a word meaning “reptile”, this will fit most contexts. In languages which do not, phrases such as “snakes and lizards”, “wriggling things”, and so forth could be used.
