Bathydevius caudactylus is only the third known instance of bioluminescence evolving in nudibranchs and the seventh known instance among gastropods.
Notes on verification
Directly confirmed by the peer-reviewed primary source (Robison & Haddock 2024), with verbatim corroboration across multiple science news outlets, though all trace back to the same original study.
