What Is A Bryozoa?

Bryozoa, also known as moss animals, are a phylum of small, aquatic invertebrate animals that typically form colonies. They are mostly found in marine environments but can also inhabit freshwater ecosystems. Bryozoans are characterized by their lophophore, a feeding structure with tentacle-like arms, and their ability to produce a gelatinous or calcareous exoskeleton. These organisms play a significant role in aquatic ecosystems, contributing to habitat structure and serving as a food source for various species.
