Hornwrack

Hornwrack is a flat, lobed colony of bryozoans. Every animal in the colony has its own task. Some are cleaners while others are responsible for providing food. Particularly in the spring, broken off pieces of a colony wash ashore regularly on the North Sea beaches. Living colonies that was ashore smell like lemon or rosemary. Therefore to determine whether or not a colony is fresh, you must smell it.

  • Distribution and habitat

    Hornwrack is commonly found in the North Sea. The colony is often attached to hard substrate, such as stones or pebbles, down to 200 meters.
