العمر
The Yucatan chinchilla-like hamster undergoes several developmental stages, beginning with the embryonic stage, when the embryo develops inside the mother and receives all necessary substances via the placenta, without feeding itself. Following birth is the infant stage, characterized by pink skin, lack of fur, and blindness, during which the mother feeds the infant milk and keeps it warm from 1 day to 4 weeks. Then comes the adult stage, when the species fully grows, acquires dense fur, and gains the ability to reproduce, lasting from 2 months to 3 years 10 months. The age of sexual maturity in the Yucatan chinchilla-like hamster occurs from 2 months 3 weeks to 3 months. The typical lifespan of the species is from 2 to 4 years, while the theoretical lifespan may reach from 4 years 1 month to 5 years 10 months.
نمط ظاهري
Hatt's vesper mice are characterized by several distinct features. The young have thin, pink skin without fur during the first days of life. Adult Hatt's vesper rats possess soft and dense fur that is grey-brown in color for camouflage among leaves, and they have large ears that capture quiet sounds in the nocturnal forest. The species also has large eyes that allow good vision in the dark, and a long, thin tail that helps maintain balance when climbing branches.

At the "Embryo" stage, offspring have a body weight from 0.1 to 4 g and a body length from 1 mm to 1.5 cm; at the "Infant" stage – a body weight from 2.5 to 9 g and a body length from 4 to 8 cm; and at the "Adult" stage – a body weight from 25 to 45 g and a body length from 9.5 to 13.5 cm.
الموطن
Hatt's vesper mice inhabit elevations up to 400 meters above sea level and are found in tropical dry forests, which are hot with a dry season and deciduous trees, and tropical moist forests, which are consistently hot and humid with large trees and vines. The species occupies terrestrial landscapes, including ground-level forests and shrublands. The climate is characterized by little precipitation in winter, with more rain in summer; it is hot with little winter rainfall and heavy summer rains; the climate is also hot with strong summer rains and little winter rainfall; and it is consistently hot throughout the year, with frequent rains but occasional dry periods.
مأوى
Hatt's vesper mice are found in tree cavities or dense shrubs, utilizing nests as their shelters. These nests are structures built or used for laying eggs and raising young. The nest’s construction involves plant fibers. The species uses these nests for reproduction, resting, and protection from the sun.
الجغرافيا
Hatt’s vesper mice are found within the Neotropical realm, specifically inhabiting dry forests of the Yucatan Peninsula, humid forests of the Yucatan Peninsula, and tropical dry forests of Mato Grosso. The species occupies dry forests of the Yucatan, humid forests of the Yucatan, and tropical dry forests of Mato Grosso. Hatt's vesper rats inhabit dry forests of the Yucatan Peninsula, humid forests of the Yucatan Peninsula, and tropical dry forests of Mato Grosso.
التغذية
The Yucatan pine-like hamster gathers food with its hands and teeth, employing a foraging strategy of searching for food at night on trees and on the ground. The species' diet includes seeds, ripe fruits, coniferous cones, and occasionally small insects, with a daily food requirement ranging from 6 g to 14 g. Among the obtained foods are beetles, butterflies, diptera, hymenoptera, bedbugs, orthoptera, dragonflies, mayflies, and net-winged insects. Yucatan pine-like hamster offspring feed on milk. True skunks, martens, weasels, true vipers, barn owls, western climbing boas, true rattlesnakes, dwarf rattlesnakes, horned owls, and Lesser Asian vipers are predators of this species.
تكاثر
Hatt's vesper mice are terrestrial animals that live and develop on land, away from bodies of water, and their young develop in nests built on or near the ground surface. The species reproduces throughout the year via viviparity, meaning the young are born alive on land and do not hatch from eggs or larvae. Embryonic development lasts 1 week and 3 days, and a litter consists of 2 to 4 young. The female cares for the young until they become independent, and only the mother exhibits parental care. Sexual reproduction is always accomplished through fertilization with no alternation of generations. The time between litters ranges from 1 month and 3 weeks to 3 months. The species reaches maturity from 2 to 3 months. Nests can be found in tree cavities or caves/cracks, and the young are raised in nests located directly on the ground surface.
