Abstract

For the first time, ultrastructural studies have been conducted on the sensory apparatus of male Tantulocarida (Crustacea). Comparative morphological analysis with specialized sensory structures of Thecostraca, known as lattice organs, has allowed for conclusions about possible homologies and further clarification of the phylogenetic position of Tantulocarida
