Bountiful Bryozoans

An interactive guide to the bryozoans of New Zealand.

Bryozoans—also known as moss animals and sea mats—are little known by most people but are a beautiful and diverse group adapted to live in many marine habitats, from the intertidal zone to the continental shelf, deep ocean trenches, and abyssal plains.

We hope you will enjoy reading and using this guide to help identify Bountiful Bryozoans in the wild.

The guide is a fully illustrated interactive pdf with high-quality images of the bryozoans in life. Just click on an image in the species index and you will be taken to a species page packed with information, beautiful images, and icons to simplify identification. An additional microscopic characters box is provided to take identifications further if desired.

New species are added as they are available, so divers, please send us your images to be considered for up and coming versions!
