Organization of ligament of acanthocephalan Neoechinorhynchus beringianus Mikhailova et Atrashkevich, 2008 (Acanthocephala, Eoacanthocephala)

摘要

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.
