Ultrastructural Evidence of Lumnescent glad openings in Metridia gerlachei giesbrecht, 1902 (Copepoda: Clanoida)
The luminescence is a feature of several marine planktonic organisms, such as bacteria, algae, cnidaria, ctenophores, crustaceans and pyrosomes, in particular, alot of pelagic crustaces have got luminescent organs (Ghirendelli, 1981, Gruner, 1994) useful for trophic, reproductive or defense purposes...
