Deep diving fur seals experience delayed heart surges after returning to land
Scientists found that deep diving fur seals experience sudden increases in heart rate hours after returning to land, indicating a delayed recovery from the physical stress of deep-sea dives. This delayed response may help the seals flush out lactic acid and replenish oxygen stores after prolonged foraging at sea. The study, which tracked heart rates of Cape and Australian fur seals, shows that recovery processes continue on land, challenging previous assumptions about how marine mammals recover from diving.
Deep diving fur seals have sudden heart rate increases hours after returning to land, showing they continue recovering from deep dives.
This delayed recovery suggests fur seals manage physical stress in ways that could inform research on endurance and recovery in extreme conditions.
The study highlights how animals adapt to survive harsh environments, offering insights into biology and resilience that benefit science and conservation efforts.
