Spiny Pocket Mouse (Chaetodipus spinatus) lives in desert scrub across Southwestern North America. It feeds on seeds and insects. Its conservation status is Least Concern.
Fascinating facts about the Spiny Pocket Mouse
- It thrives up to 900 m (3,000 ft) above sea level on Gulf of California islands, showing it can cope with thinner air and cooler night temperatures. Living at these elevations means the mouse must extract most of its water from seeds and green vegetation, because free water is scarce. This ability to live high on desert islands expands its range across southern Nevada, southeast California, and the Baja Peninsula, illustrating a flexible diet and water-conservation strategy.
- Its tail stretches longer than its whole body, measuring 126% of head-plus-body length.
- Weighing only 13-18 g (0.46-0.63 oz), the spiny pocket mouse. The mouse's main predator, feral cats.
- Being nocturnal lets this mouse escape the desert's scorching daytime heat, seeking refuge in burrows where it sleeps, breeds, and raises its young.
- Its range stretches from southern Nevada across the Baja California Peninsula to southeast California, yet it avoids agricultural lands. Because it occupies a wide, mostly undisturbed desert belt, the species faces little risk of extinction.
