Conopeum seurati is an encrusting bryozoan. The colony form varies from brownish-white lace-like sheets, irregular encrustations to spherical balls of zooids. The colony shape is largely influenced by the substrate type, which includes estuarine plants, such as Ruppia, as well as hard substrates.
The full distribution of this species is unknown, but it has mainly been recorded from Northern Europe and the Mediterranean. It has also been found in Florida and New Zealand, where it is regarded as an introduced species. Conopeum seurati is an estuarine, fouling bryozoan that is found in the lower intertidal and shallow waters of brackish environments.
