Calves of white-beaked dolphins typically nurse for approximately 18 months, extending their dependency period longer than many other small cetacean species.
- 05
White-beaked dolphins produce echolocation clicks at frequencies between 40 and 130 kilohertz, enabling precise navigation and prey detection in murky Atlantic waters.
- 04
Genetic studies reveal white-beaked dolphins diverged from Atlantic white-sided dolphins approximately 4 to 5 million years ago during the Pliocene epoch.
- 03
The white-beaked dolphin's diet consists primarily of fish species like capelin and herring, with stomach content studies showing these cetaceans consume up to 10 kilograms of prey daily.
- 02
Social groups of white-beaked dolphins typically contain 5 to 50 individuals, though aggregations can exceed 1,500 dolphins during feeding events in productive waters.
