record breakers: Which Animal Can Hold Its Breath the Longest?
Many aquatic creatures have developed unique strategies for obtaining oxygen. While some, like certain spiders, capture air bubbles, others depend on holding their breath for extended underwater dives.
The length of these dives varies based on the animal and the reason for submergence. Wilco Verberk, an ecology professor at Radboud University, noted the distinction between surviving underwater when trapped and voluntarily holding one’s breath.
Whales are among the mammals known for impressive dives. A 2020 study by Verberk, Spicer, and their team detailed key adaptations that enable whales to achieve this, including slowed heart rate and metabolism. They also redirect blood flow, temporarily shut down organs, and utilize large amounts of respiratory proteins to store and release oxygen, according to Spicer.
Whales can also switch to anaerobic metabolism, generating energy without oxygen. While less efficient and slower, this process allows them to cope with lactic acid buildup, Spicer added.
Elephant seals have been known to dive for up to two hours, notably when predators are nearby.
Ectotherms for the Win
While whales are champions among warm-blooded animals, ectotherms, or cold-blooded animals, boast the longest underwater dives.

Freshwater crocodiles have been recorded staying submerged for up to 402 minutes when sensing danger. However, the loggerhead sea turtle holds the record, with dives lasting around 610 minutes, according to a 2007 study. Other studies have noted maximum dive durations of 480 minutes.
These ectotherms share oxygen-saving adaptations with mammals but conserve energy by not regulating their body temperature.
Spicer noted that the lower running costs of ectotherms, due to temperature’s effect on metabolism, make a notable difference. Leatherback turtles can dive deeper than most whale species and dramatically reduce their metabolism in cold waters, allowing them to rest on the sea bottom for hours.
What’s next
Further research into the physiological adaptations of marine animals promises to reveal even more about the remarkable strategies they use to thrive in aquatic environments. Understanding these adaptations is crucial for conservation efforts, especially as climate change and other environmental factors continue to impact marine ecosystems.
