Desert tortoises have a brilliant strategy for surviving the punishing heat of the American Southwest: they burrow. When temperatures soar, these slow-moving reptiles dig deep into the ground to find cooler, more humid areas where they can retreat from the harsh sunlight. Their burrows act as both a refuge from the heat and a place to store water. Tortoises are able to store water in their bladders, which they can slowly absorb to keep hydrated during droughts. These reptiles are known for their patience and resilience, emerging from their burrows only when it’s cooler, usually at dawn or dusk. This ability to avoid the hottest part of the day allows them to conserve water and stay safe.
6. Kangaroos: Licking to Stay Cool
Animalia
Kangaroos, iconic symbols of the Australian Outback, have their own ways of coping with heat. Unlike many other mammals, kangaroos use a unique technique to cool down: they lick their forearms. This may seem like a curious habit, but the moisture left behind from their saliva evaporates from their skin, cooling them down in the process. Kangaroos are also known to rest in the shade during the hottest part of the day and remain relatively inactive, conserving energy. Their large, muscular tails are also effective at stabilizing their movements and ensuring they don’t overexert themselves while hopping across the sun-baked landscape.
7. Spiny Desert Larks: Staying Active in the Early Morning
Animalia
Spiny desert larks have adapted to survive the harsh conditions of the desert by being early risers. These birds are most active during the early morning hours, before the sun fully rises and the temperatures reach unbearable levels. They forage for food and drink early, ensuring they’ve met their daily hydration needs before the heat sets in. By staying cool in the early morning and taking shelter during the scorching midday heat, they minimize their exposure to the sun. This clever strategy ensures they have the energy to make it through the day and avoid the deadly heat of the desert.
8. Saharan Silver Ants: The Heat Champions

Known as the fastest and most heat-tolerant ants in the world, Saharan silver ants have adapted to thrive in temperatures that would be deadly to most other creatures. These ants can survive body temperatures up to 128°F (53°C), which is nearly 10°F higher than any other known animal. Their secret lies in their unique bodies, which are covered in silvery hairs that reflect sunlight, preventing them from overheating. These ants are highly active during the hottest part of the day, foraging for food in the blistering heat, and their heat tolerance is so advanced that they have evolved to be the dominant species in their harsh desert environment.
9. Gila Monsters: Slow and Steady Wins the Survival Race
Animalia
The Gila monster, a venomous lizard found in the deserts of the American Southwest, takes a more methodical approach to dealing with extreme heat. Rather than staying active during the day when temperatures are unbearable, Gila monsters are mostly nocturnal or crepuscular. During the hottest parts of the day, they retreat to their burrows, where they remain in cooler conditions. They also have a slow metabolism, allowing them to conserve energy and moisture when water sources are scarce. Gila monsters are known to drink large amounts of water when available, storing it for later use when conditions become harsh again.
10. Zebras: Sweating It Out

Zebras, native to the African savannas, are built for high temperatures, but they still need to stay hydrated to thrive in the heat. Their strategy? They sweat it out. Unlike most mammals, which sweat primarily to regulate temperature, zebras produce a special kind of sweat that contains a substance called latherin. This compound causes their sweat to foam, helping it evaporate more effectively and cool their bodies down faster. The foamy sweat also acts as a protective barrier against insects like ticks and flies, which can be a nuisance in the African heat. By sweating, evaporating, and keeping their activity to a minimum during peak heat, zebras are able to maintain a steady body temperature throughout the day.
11. Jerboas: Specialized for Dry Heat
