Abstract

The first data on the histology and ultrastructure of ligament of acanthocephalan Neoechinorhynchus beringianus have been reported. The analyzed acanthocephalans are shown to have a single ligament, which is assumed to be connected to the cutaneous muscles by its anterior part. The ligament wall is composed of a muscle tissue, which is similar to that of cutaneous muscles. The existing assumption regarding the identification of a ligament cavity as a coelom is discussed.
