ABSTRACT: Trophi is only
found in rotifers. The trophi has been used as a tool to identify species as
well as an instrument for reconstructing the phylogeny of the organism,
morphometric analysis, etc. Twelve species of rotifers of the genus Brachionus Pallas, 1766 were collected
from different regions of the state of Aguascalientes, Mexico. An
ultra-structure analysis was performed to examine the structural composition of
the trophi of each species using scanning electron microscopy (SEM). The SEM
observations show significant differences in the structural composition of each
species, with the most considerable differences found in the trophi of B. budapestinensis.
