Summary
An exploration of why belugas, orcas, and dolphins eat ice as a hydration supplement in aquariums and an overview of their high intelligence.
Highlights
Hydration through ice00:00:00
Belugas, orcas, and dolphins eat ice to stay hydrated because they struggle to drink plain water in captivity, often mistaking it for saltwater.
Dietary needs and intelligence00:00:25
In the wild, marine mammals get water from live fish. In aquariums, they are fed frozen fish, necessitating ice as a moisture supplement. Belugas also display high intelligence, social complexity, and a gentle nature.
