鼷鹿科 Tragulidae (Sub-family of Artiodactyla)
鼷鹿科(Tragulidae)源于拉丁语 tragus("山羊")和拉丁语 -ulus (缩写后缀),意为 "小山羊",指的是该科的所有成员尽管体型较小,但外表却像山羊.
Tragulidae, from Latin tragus (“goat”) and Latin -ulus (diminutive suffix), means “small goat”, in reference to the fact that all the members of this family have a goat-like appearance despite being smaller.
