Morphology, ecology, and molecular biology of a new species of giant larvacean in the eastern North Pacific: Bathochordaeus mcnutti sp. nov.

B. mcnutti are 3–10 cm long. Their tails have a blue outline. Gravid individuals descend as low as 800 m, but spawning is thought to happen above 100 m. The CO1 gene is ~12% different between B. mcnutti and B. strygius.
