The Sensory Structures of the Carapace of Male Tantulocarida (Crustacea) Are not Homologous to the Lattice Organs of Thecostraca.

Ultrastructural studies on the sensory apparatus of male Tantulocarida (Crustacea) have been conducted for the first time. Comparative morphological analysis with the 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.
