Xerocoles are:

Explanation

**Step-by-Step Solution:**

1. **Definition of Xerocoles**: Xerocoles are animals that have adapted to survive in xeric (dry) conditions, particularly in desert environments. These adaptations allow them to thrive in areas with limited water availability and extreme temperatures.

2. **Characteristics of Xerocoles**: Xerocoles exhibit several physiological and behavioral adaptations that enable them to cope with the harsh conditions of their habitats. These adaptations include:
- **Water Conservation**: Xerocoles have mechanisms to minimize water loss. For example, their feces contain very little moisture, which helps conserve water.
- **Nocturnal Behavior**: Many xerocoles are nocturnal, meaning they are active during the night when temperatures are cooler. This behavior helps them avoid the extreme heat of the day.
- **Burrowing**: Some xerocoles, like certain rodents and snakes, create burrows in the sand. These burrows provide shelter from the heat and help maintain a more stable temperature.
