Аннотация
The anatomy and ultrastructure of “amphipod silk” glands in Ampithoe rubricata Montagu 1818 (Ampithoidae) have been studied. The morphology and ultrastructure of the glands in pereopods 3 and 4 have been examined in semithin and ultrathin sections using light and transmission electron microscopy. The glands of two types producing secretions different in their chemical compositions are observed in these pereopods. The ducts of the glands of both types lead to a common reservoir in the dactylus. Each gland comprises several secretory cells and one duct cell. The structure earlier regarded as the chitin wall of the duct is the cytoplasm of the duct cell; the presence of this cell in the studied glands is demonstrated for the first time. The secretory cells contain one or two nuclei and form rows along each duct cell. A new, previously unknown type of crustacean glands is described.
