Abstract

The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North-eastern Atlantic) in 2021 by bottom trawling. The lack of dermal melanophores combined with a normal retinal pigmentation, lead us to considerate the specimen as leucistic. This is the first case of leucism in E. spinax and the second record of colour aberration in the family Etmopteridae. A comprehensive updated review of published literature on albinism and leucism in chondrichthyans is also provided.

丝绒腹灯鲨(鳞目:鳞鳍鲨科)白光现象的首例记录

报道捕获一条皮肤颜色异常的丝绒腹灯鲨雌性标本。该标本于2021年在西班牙北部(大西洋东北部比斯开湾)通过海底拖网捕捞。皮肤黑色素细胞的缺乏加上正常的视网膜色素沉着，导致我们认为该标本为白斑。这是棘棘棘棘的第一例亮色现象，也是斑蝶科的第二次色差记录。还提供了有关软骨鱼白化病和白化病的已发表文献的全面更新综述。
