White-beaked Dolphin

Fascinating facts about the White-beaked Dolphin

• The white-beaked dolphin has up to 92 vertebrae, the highest count among oceanic dolphins, giving it a uniquely flexible spine. This remarkable skeletal feature is part of its robust build, which also includes a short beak and a powerful body. Adults grow to 2.3-3.1 m in length, a size supported by that extensive vertebral column. The high vertebrae number therefore underpins the species' strong swimming ability.
• The humerus of the right flipper is longer and more robust than that of the left, a clear sign of lateralised behaviour in this dolphin. Such asymmetry may influence how it steers or maneuvres while swimming. The flippers themselves are darker grey than the body, matching the colour of the dorsal fin and fluke. This combination of structural and colour traits helps the animal maintain efficient, coordinated movement in its cold-water habitat.
• White-beaked dolphins emit sonar clicks that peak at 115 kHz and social whistles around 35 kHz, sounds that can travel up to 10 km and be heard by other members of the species. These acoustic signals are crucial for maintaining contact within their typical groups of fewer than ten individuals.
• White-beaked dolphins are capable of short bursts of speed, reaching up to 30 km/h despite usually travelling much slower. When hunting or evading, they can plunge to depths of at least 45 m, a dive that matches their ability to navigate the cold, temperate waters of the North Atlantic. Their agility is also shown by frequent bow-wave riding and leaping clear of the sea surface, behaviours that complement the rapid swimming and deep diving capacities.
• White-beaked dolphins have been observed feeding with larger cetaceans such as killer, fin, and humpback whales. These mixed-species feeding events occur while the dolphins typically travel in groups of fewer than ten individuals, though they can gather in larger aggregations when prey is abundant.
