Bryozoans are unnoticeable and unknown marine animals, who reside in colonies on all sorts of substrates. The colonies exist mainly out of mossy structures, in which the individuals can be bearly spotted with the naked eye. A little more research into this species shows a surprisingly variety in colours and shapes. The faunistical properties of this species are also very interesting.Distribution patterns and habitat preferences know a great diversity. This article, in which is included a photographic impressum, presents us with a view on the diversity of the Dutch marine Bryozoa.
