Creature Countdowns
| For animals that live in areas where resources such as food and water are scarce for long periods of time, the ability to conserve fat and water in the body can mean the difference between life and death. A stunning example of resource conservation comes from the Bactrian camel, a two-humped ungulate that lives in the rocky and arid regions of Central and Eastern Asia, where temperatures range from -20°F in winter to 100°F in summer. Bactrian camels have a couple of key adaptations that help them to survive these harsh conditions. First, their humps are filled with fat, which can be converted into energy and water in lean times. Second, they can forgo sweating until their body temperatures reach nearly 105°F. |
