Anomalous lanugo coat colourations in sub-Antarctic fur seal (Arctocephalus tropicalis) pups born on Marion Island
International audience Anomalous pelage colourations are not uncommon amongst pinnipeds but have not been documented in sub-Antarctic furseals (Arctocephalus tropicalis). Fur seals (Arctocephalus spp.) have been monitored on Marion Island since 1973, and aspart of the long-term monitoring programme,...
