Distribution of catecholamine-containing neurons in the brain of two species of crustaceans hermit crab Pagurus middendorffii and the king crab Paralithodes camtschaticus was studied by immunocytochemical methods using an antibody against tyrosine hydroxylase (TH). In both species of the studied crustaceans, morphologically different types of TH-immunoreactive neurons are detected in cell clusters in brain protocerebrum, deutocerebrum, and tritocerebrum. Similarities and differences in the topography, numbers, and morphology of TH-positive neurons in different brain structures in the hermit crab and king crab are discussed.
