Acanthocephala Animalia Flora and Fauna Biology


The acanthocephalans number about 1150 species. They are worm-like creatures without a gut and all of them parasitic. They have elongate, dorso-ventrally flattened forms, ranging from 2mm to approximately 1 metre in length. The most characteristic feature of this phylum is a spiny proboscis which can be everted to act as an attachment organ.
