The Natural History Museum, London (NHM) is currently undertaking one of the biggest collections moves in history, around 38 million specimens total (with 28 million moving off site). A diverse range of collections are expected to move to the new site in Reading including fossils, wet, dry, taxidermy and osteological specimens. This blog will focus on some examples and challenges faced when preparing the bryozoan collections to move.

Bryozoans are an astounding yet little known phylum of predominantly colonial aquatic invertebrate animals, found in both freshwater and marine ecosystems. Known as the ‘moss animals’, for a long time, they were thought to be plants which still confounds the record of this group in aquatic collections due to their growth patterns encrusting on rocks, as seaweed-like and sometimes as gelatinous blobs. There are bryozoan reefs which support diverse marine species, they are recognised bioindicators in aquatic habitats and are ‘blue carbon’ stores (Porter, J, S. et al., 2020).
