Dendronotus claguei is a species of sea slug in the family Dendronotidae.

[1] It was discovered by the MBARI while exploring the Alarcón Rise, found on an inactive hydrothermal chimney.

The scientists collected two specimens, one 7 mm in length and the other 18 mm in length.

Their discovery raised questions on how nudibranchs were surviving 2,370 m below the surface, living in a low food environment where very few other animals could be found.
