Trinchesia Explained

Trinchesia is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae.^{[1] [2]} All species were transferred to Tenellia as a result of a DNA phylogeny study in 2016.^[3] The genus was dismembered and broken into several smaller genera in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.^[4]

Trinchesia species feed on hydroids.
