深海环境与广泛的解剖学上的特殊形态有关,允许在这种低光或无光环境中进行伪装。在派力肯(Eurypharynx pelecanoides)中有专门的超黑色着色记录,但在其他主要居住在深海的远洋鳗类鱼中还没有进行过探索。组织学检查显示,在表层真皮中有一层游离的黑色素体,这与吞鳗囊咽、短尾鹬鳗Cyema、沙锥鳗Serrivomer和鹬鳗Avocettina和Nemichthys的特化超黑色伪装一致。这些分类群的解剖结构与先前描述的超黑形态一致,除了Nemichthys,Avocettina和Serrivomer都有大量的游离黑素体和黑素细胞。考虑到这种形态的背景下anguiloid鳗鱼在深海环境中的演变,表明重复的超黑着色内anguiloid独立的演变,更具体地与深海栖息地和生产的生物发光的类群更大的发展。
The deep-sea environment is associated with a wide range of anatomically specialized morphologies allowing camouflage in this low or no light environment. Specialized ultra-black coloration has been documented in the pelican eel,Eurypharynx pelecanoides, but has not been explored in the other largely deep-sea inhabiting pelagic anguilloid eels. Histological examination of the integument revealed a layer of free melanosomes in the superficial dermis consistent with specialized ultra-black camouflage in the swallower eelsSaccopharynx, the bobtail snipe eelCyema, the sawtooth eelsSerrivomer, and the snipe eelsAvocettinaandNemichthys. The anatomy in these taxa is consistent with the previously described ultra-black morphology, except thatNemichthys,Avocettina, andSerrivomerhave both large amounts of free melanosomes and melanophores. Consideration of this morphology in the context of anguilloid eel evolution in the deep-sea environment suggests repeated independent evolution of ultra-black coloration within the anguilloids, and greater development in the taxa more specifically associated with the bathypelagic habitats and the production of bioluminescence.
