1. Kangaroo Rats: Kangaroo rats are small rodents found in desert regions of North America. They can survive for months without drinking any water. They extract the moisture they need from the seeds they eat and can even convert fat into water.
2. Camels: Camels are well-known for their ability to go for long periods without drinking water. They have specialized adaptations, such as humps that store fat, which can be broken down into water during periods of water scarcity.
3. Australian thorny devil: Australian thorny devils are desert-adapted lizards that can survive entire seasons without access to water. They get the moisture they need from absorbing water vapor through special body structures called papillae.
4. Tortoises: Tortoises, such as the desert tortoise, can go for long periods without water. They have slow metabolisms and can store water efficiently in their shells.
5. Scorpions: Scorpions are found in a variety of habitats, including deserts and other dry environments. They have physiological mechanisms that allow them to conserve water, such as the ability to reduce their activity and metabolic rate during periods of drought.
6. Snakes: Some snakes, particularly those in arid regions, have adaptations to survive without water for extended durations. They can conserve water by reducing their activity and metabolizing stored energy.
7. Insects: Certain insects, such as darkling beetles and mealworms, can survive long periods without water by conserving water and extracting moisture from their surroundings.
8. Tardigrades: Tardigrades, also known as water bears, are microscopic animals that can enter a state of suspended animation called cryptobiosis. In this state, they can survive extreme conditions, including extreme dehydration, for many years.
It's important to note that survival without water also depends on the specific species, their adaptations, and the surrounding environmental conditions.
