Welcome to the reference collection of Mediterranean bryozoa.

Species identification is a key challenge to sea research and management (is critical for monitoring and conservation efforts). However, there are few expert taxonomist, and particularly for this group, the bryozoans. Reference collections are the result of several years working on a particular taxon. The collection of Mediterranean bryozoans has been gathered in the course of diverse scientific research projects on marine invertebrates, which have generated a great deal of samples that after being processed (specimens are collected and identified) sit unnoticed on a shelf. Our objective is to convert that work and knowledge into a useful reference collection that can be used by others throughout the actual technological platforms. This collection includes more than 300 species from the western Mediterranean. Each species is presented with a detailed set of SEM images depicting the most characteristic features, the geographical location of collection, the related ecological information, the relevant bibliography and links associated.
