First record of albinism in the swell shark, Cephaloscyllium ventriosum (Elasmobranchii: Carcharhiniformes: Scyliorhinidae) [PDF]
Acta Ichthyologica et Piscatoria, 2017 We report the first record of albinism in the swell shark, Cephaloscyllium ventriosum (Garman, 1880). The specimen was caught off the southern part of the Baja California Peninsula, Mexico. The shark had no skin pigmentation and golden-coloured eyes. The
