Fionidae Explained

Fionidae is a family of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the superfamily Fionoidea.^[1]

Taxonomic history

This family was expanded to include Tergipedidae, Eubranchidae and Calmidae as a result of a molecular phylogenetics study.^[2] This was reversed in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.^[3]
