Danh từ

Số nhiều: otoliths

This term is primarily used in specialized scientific contexts, specifically within ichthyology, anatomy, and otology. It carries a neutral, technical tone and is rarely encountered in general conversation unless discussing biological research or vestibular disorders.

In fisheries science, the word often implies a tool for chronological dating, as the growth rings within a fish's otolith are analogous to tree rings. In a medical context, it refers to the microscopic crystals whose displacement can cause benign paroxysmal positional vertigo (BPPV).
