Pilot Whales in Iceland
Long-finned pilot whales are defined by their social bonds. Globicephala melas is a medium-sized toothed whale that travels in cohesive groups, often maintaining tight formations at the surface. In Iceland, they are typically found in deeper offshore waters but may occasionally be seen in areas like Skjálfandi Bay.
Their diet consists mainly of squid and fish, and they are capable of deep dives in search of prey. Like other toothed whales, they use echolocation to navigate and hunt.
At the surface, pilot whales appear calm and deliberate. Groups move together, surfacing in synchrony, often giving the impression of a single, coordinated unit. Their rounded head, or melon, and dark body are characteristic features.
Social structure is central to their behaviour. Pods can consist of dozens of individuals, and strong bonds between members mean they often stay together even under stress. This cohesion is thought to play a role in the species’ tendency toward mass strandings.
Encounters with pilot whales are less about individual animals and more about the group as a whole, a collective presence moving through the water.
