Newborn Rosso’s dolphins are light grey in colour and darken as they grows; during life, more and more white scars appear, the result of love skirmishes and other social activities, so that older individuals are almost white.
The population in the north-western Mediterranean is estimated to be 16,000 individuals, which mainly frequent waters from 600 to 1,000 m depth. This marine mammal is found especially on the continental slope and submarine canyons where it feeds on fish and cephalopods. It is a particularly sociable species and lives in small groups, occasionally also seen with pilot whales and striped dolphins.
The current IUCN Red Listing for the Mediterranean subpopulation is Endangered.
