Bathochordaeus charon (Chun, 1900)[1]

First description of this very large larvacean was provided in 1900 by Carl Chun from two specimens collected during the Valdivia expedition in 1898–1899. The first definitive record of Bathochordaeus charon since its original description was obtained in 2016 by R. E. Sherlock, K. R. Walz and B. H. Robison, using a ROV in the Monterey Bay, California, USA.

A small number of Bathochordaeus have been found near Bermuda, in the Indian Ocean, or off the Nansei islands but they differ significantly from B. charon.^[2]
