Florida mouse

Podomys floridanus

Also known as: Florida Deermouse

NTNear Threatened

The Florida mouse is the only mammal species found naturally in Florida and nowhere else. It lives on dry sandy uplands, often sharing the deep burrows dug by gopher tortoises. Large ears, big dark eyes, and a warm brown back suit a nocturnal life above and below ground. Fire keeps its scrub and open woodland habitat usable by preventing dense vegetation from closing in.

Elevation

From 200 georeferenced records, the Florida mouse is recorded from sea levelsea level to 63 m207 ft, with half of sightings below 41 m135 ft.

Each band shows the share of georeferenced sightings that fall within it. Records cluster where people live and hike, so low, populated elevations are over-represented. Read this as observation density, not true abundance.

Eats

A sample of documented feeding relationships, filtered to species that also occur in the US. Diet and predators vary by region and season, and this is not a complete list, many animals eat, and are eaten by, more than what has been formally recorded here.

Life history

The Florida mouse (31 g1.1 oz) is an omnivore that first breeds around 0.1 years, carries a 23-day gestation, and bears about 2.6 young per litter. Maximum recorded longevity is 7.4 years.

Commonly confused with

Animals people sometimes mistake for the florida mouse, and how to tell them apart.

A mouse tied to sandy uplands

Florida mice favor scrub, sandhill, and open pine woodland on well-drained soil. Their large ears and eyes are useful after dark. They eat seeds, fruit, fungi, and insects, then carry food through cover. Owls, snakes, foxes, and other hunters keep them close to shelter.

Sharing a tortoise burrow

Gopher tortoise burrows provide stable temperature and protection from fire and predators. The mouse may also dig side passages or use other underground shelters. Sharing doesn’t mean the two animals constantly interact. The burrow simply creates valuable living space that many Florida animals can use.

Fire keeps the habitat open

Regular fire holds back thick shrubs and supports the patchy ground layer this mouse needs. Development and fire exclusion break remaining uplands into smaller pieces. The species is endemic, meaning found nowhere else, so losses can’t be replaced from another state. Survey records reveal confirmed locations, not a direct statewide population count.
