A shot in the dark: Comparative morphology of the bioluminescent tube organs in tubeshoulders (Platytroctidae)
Fig 1
External anatomy of the postcleithral and caudal tube organs (A) Platytroctes apus (SIO 55-244, 136.4 mm SL) showing location of postcleithral tube organ (left white box) and caudal tube organs (right white box).
(B) Postcleithral tube organ in P. apus (SIO 77-54) showing terminal opening and modified scale (ms). (C) Caudal tube organs on dorsal margin of caudal peduncle in P. apus (SIO 55-244). Arrows indicate the terminal opening of the postcleithral and caudal tube organs.
