New observations and ontogenetic transformation of photogenic tissues in the tubeshoulder Sagamichthys schnakenbecki (Platytroctidae, Alepocephaliformes)
Several species of the luminescent tubeshoulder fish (family Platytroctidae) show extensive ontogenetic transformations in the development of bioluminescent structures from larvae to adults. Several types of luminescent tissues are present in platytroctids, although these tissues are poorly known fo...
