Skin color aberrations are naturally occurring abnormal pigment patterns that are generally
rare among chondrichthyans. In this study, we highlight different skin color aberrations from …

Sightings of anomalously all-white (leucistic) or all-black (melanistic) individuals are rare in
nature, with information on hypo-and hyper-pigmented short-beaked common dolphins …
