First account of apparent alloparental care of a long-finned pilot whale calf ( Globicephala melas ) by a female killer whale ( Orcinus orca )
Interactions between killer whales ( Orcinus orca (Linnaeus, 1758)) and long-finned pilot whales ( Globicephala melas (Traill, 1809)) have been documented on numerous occasions, usually involving predation events and pursuits. Here, the first documented account of a long-finned pilot whale calf seen...
