This article investigates the lexical-semantic principles underlying the naming of invertebrates in English and Uzbek from a comparative perspective. The findings indicate that English invertebrate zoonyms are predominantly descriptive and associative, motivated by salient perceptual features such as shape, texture, habitat, behavior, and resemblance to familiar objects or animals. In contrast, Uzbek invertebrate naming is largely characterized by a strong taxonomic-terminological layer, with a high proportion of internationally standardized and Russian-mediated loan terms, as well as collective category names. The comparative analysis highlights the productivity of compounding patterns in English (N+N, Adj+N), whereas Uzbek demonstrates greater dependence on scientific classification and terminological standardization.
