Due to their circular mouth, they are named Cyclostomata. They are parasitic, usually feeding on fish in their adult stage. Morphologically, they resemble eels. They are known to be the only living vertebrates without true jaws, hence called Agnatha.

Distinguishing characteristics Larvae are triangular in shape and greatly compressed. Each lateral surface covered by a chitinous valve.The bryozoan Bugula neritina is the source of complex polyketides of the bryostatin series. 315 Particularly high concentrations are present in the larvae and juveniles, where they provide protection against fish predators. 316–319 Bryostatins are potent activators of protein kinase C and exhibit anticancer properties. 315 Bryostatin 1 (164) (Scheme 20) has reached phase II clinical trials ... Cheilostome bryozoans have a complex life cycle with distinct asexual and sexual modes of reproduction (Taylor, 2020; McKinney and Jackson, 1991). Asexual reproduction allows for a single colony to grow larger by increasing the number of zooids in the colony. The sexual stage of the cheilostome bryozoan life cycle leads to the ……
