History: “On October 2011, a newborn franciscana dolphin with an anomalously coloration was sighted in Babitonga Bay, southern Brazil. The calf was totally white.” (Cremer et al. 2014). The authors reported that “between first and last sighting of the white calf (113 days) the color has not changed”, that "this is the first case of a white franciscana dolphin” and considered that this “could be an albino dolphin.”

Clinical features: As described by Cremer et al. (2014), “the calf was totally white” and they “considered the possibility that this franciscana could be an albino dolphin.”

Prevalence: As described by Cremer et al. (2014), this white coloration had never been reported previously in this species, “despite the high number of dead franciscanas recovered each year along the distribution of the species, resulting from accidental capture in fishing nets.” This led Cremer et al. (2014) to believe “that this is a very rare characteristic for this species.”
