Observations of long-finned pilot whale (Globicephala melas) calves less than one year old, including neonates and a very recently born calf, in northern Norway
Long-finned pilot whales (Globicephala melas) are a widespread, highly social deep-diving cetacean species ranging from the sub-tropics to the High Arctic. Information on this species’ life history at higher latitudes is limited. Opportunistic observations of pilot whale calves were made in the spri...
