Rice rats in the Florida Keys occasionally climb in vegetation, but never higher than 90 cm (3.0 ft). [149] Marsh rice rats are very clean and extensively groom themselves, perhaps to keep their fur water-repellent. [150] They are aggressive towards conspecifics and emit high-pitched squeaks while fighting. [74]
The skull of the Florida panther is broader and flatter with highly arched nasal bones. [38] Reportedly only seventy adult animals are alive, [39] and a 1992 study estimated that the subspecies would become extinct between 2016 and 2055. [40] It was chosen in 1982 as the Florida state animal by the state's schoolchildren. [41]
The breeding season of eastern wood rats depends on the climate. Those in warmer climates (e.g. Florida and Georgia) can reproduce all year, while eastern wood rats in higher latitudes (e.g. Kansas and Nebraska) breed from early spring to mid fall. Their estrous cycle lasts between 3 and 8 days, while gestation lasts between 32 and 38 days. [11]
The rat's habit of building large nests ("4ft by 6ft homes") was seen as proof that "even wildlife in Florida want enormous homes." [ 29 ] Novelist Lydia Millet paid homage to the woodrat in her 2008 novel How the Dead Dream , a story of a young real estate developer from Los Angeles who, after some personal turmoil, takes an obsessive interest ...
The round-tailed muskrat is a semiaquatic and nocturnal species native to the southeastern United States. [3] Limited sexual dimorphism is seen among round-tailed muskrats, with female adults weighing an average of 262 grams (9.2 oz) and male adults measuring at a slightly heavier average of 279 grams (9.8 oz). [3]
There are a few feral rat species in South Florida, including brown rats (Rattus norvegicus), but black rats are considerably more populous than any other species of rat. All exotic rats compete with native mice and rodents for food and shelter, but the black rat is noted for significantly affecting the endangered Key Largo woodrat ( Neotoma ...
Muskrats, like most rodents, are prolific breeders. Females can have two or three litters a year of six to eight young each. The babies are born small and hairless and weigh only about 22 g (340 gr). In southern environments, young muskrats mature in six months, while in colder northern environments, it takes about a year.
