Animals that can hold their breath for incredibly long times


Imagine plunging thousands of feet beneath the ocean’s surface, the pressure immense and sunlight a distant memory. In this realm, some animals possess the remarkable ability to hold their breath for extraordinary lengths of time. Let’s explore these underwater champions and the secrets behind their breath-holding prowess.

The Champions of the Deep

Taking the crown are the sea turtles. These shelled reptiles can hold their breath for a staggering 4 to 7 hours, with the record going to a loggerhead sea turtle that stayed submerged for over 10 hours! Their slow metabolisms and the ability to slow their heart rate allow them to conserve oxygen during long dives.

The Underwater Nomads

Whales are masters of deep dives. The Cuvier’s beaked whale holds the record for the longest breath-hold by a mammal, clocking in at an unbelievable 3 hours and 42 minutes. Sperm whales are no slouches either, managing dives lasting up to 2 hours. These deep-sea hunters have adaptations like specialized blood vessels that store oxygen efficiently.

The Masters of Stealth

Among mammals, seals are breath-holding champions. Weddell seals can hold their breath for an impressive hour, allowing them to hunt for prey in the icy depths. Their streamlined bodies and reduced blood flow to non-essential organs during dives further enhance their breath-holding abilities.

The Avian Aeronauts

While not as long as some underwater breath-holders, some birds deserve a mention. Emperor penguins, known for their deep dives for fish, can hold their breath for around 20 minutes. Arctic loons are another example, staying submerged for up to 17 minutes while hunting.

Insights for Science and Beyond

Studying these breath-holding animals offers valuable insights for science and medicine. Understanding how they conserve oxygen could lead to advancements in treating conditions like stroke and heart attack. Additionally, research on these animals might inspire new underwater technologies for exploration and survival.


The animal world holds incredible examples of breath-holding abilities. From the majestic whales to the resilient sea turtles, these creatures have evolved remarkable adaptations to thrive in the underwater world. As we continue to learn from them, the secrets they hold may unlock breakthroughs in science and beyond.
