Summary
The remarkable diving and foraging migrations of the seals have been revealed by diving instruments attached to them, which are recovered when they return to the rookery. They show that elephant seals are the deepest and longest divers of all the seals and most of the whales. They migrate twice a year to feed on round-trip voyages of up to 8,000 km. The behavioural and physiological adjustments to long, deep diving are described.
