Pycnoclavella

Pycnoclavella is a genus of sea squirts first circumscribed by Walter Garstang in 1891.^[1] The generic name comes from the Ancient Greek πυκνός (puknós) meaning "closely united".^[1] In 1990, Patricia Kott placed Pycnoclavella in its own family, Pycnoclavellidae, but in 2008 it was moved back to Clavelinidae.^[4]
