Long Finned Pilot Whale
The long-finned pilot whale has a large, bulbous forehead and a long, robust body, which can measure up to 6.3 metres in length. The prominent dorsal fin is wide at the base and deeply curved. This species of pilot whale has very long, tapered pectoral fins that can measure about a quarter of the body length. Long-finned pilot whales are highly social animals that have been recorded in groups of just a few animals to aggregations of over 1000 individuals; group sizes in the Hebrides are small.
