| contents | First description of leucism in the deep-sea angular rough shark (Oxynotus centrina) and the first documented pigment disorder in family Oxynotidae Gill, 1912. Gajić, Andrej A de Loose, Emilie Martin, Andrea G Neuman, Elias Karalić, Emina Animals Sharks Female Male Pigmentation Disorders Fish Diseases Pigmentation Gills The capture of a rare, critically endangered adult angular rough shark, Oxynotus centrina (Linnaeus, 1758), with abnormal coloration is reported in this paper. The shark exhibited a partial reduction in pigmentation, resulting in an overall pale appearance with white-greyish patches. Since the retinal pigmentation appeared normal, the shark was considered leucistic. This represents the first documented case of leucism in this species and the first colour disorder reported in the family Oxynotidae Gill, 1912. Despite the atypical appearance, the physical health of the shark seemed unaffected, supporting the notion that pigment disorders in deep-sea sharks do not inherently impair survival and growth. Full morphometric characteristics are presented and compared with those of a normal individual of the same sex caught in the same area, showing no differences. |
