- The red-tailed phascogale gives birth to up to 8 young between June and August. Males die soon after mating with females.
- Males die en masse after their first mating due to stress, so they usually live no more than 11–12 months.
- The female gives birth to up to 13 young but can raise only eight (matching the number of teats).
- The animal is arboreal and nocturnal and can leap up to two metres.
- The animal almost never drinks water, obtaining moisture from its food.
- The red-tailed phascogale is a small carnivorous marsupial weighing about 40–60 g.

Տարիք
The red-tailed mousesack has a typical lifespan of from 3 years and 10 months to 6 years and 4 months, although the maximum recorded lifespan is 3 years, with a theoretical lifespan ranging from 2 years and 4 months to 4 years and 9 months; the species reaches sexual maturity at from 11 months to 11 months and 1 week. The embryo develops inside the mother for a very short time before birth, after which the young lives in the mother's pouch and feeds only on her milk for a period of from 3 weeks to 4 months. Following this, the animal enters the adult stage, during which it is capable of reproduction, but males do not live long, with this stage lasting from 4 months to 1 year.

The little mouse opossum is a species characterized by small size: body length ranges from 9 mm to 1.3 cm, and weight from 43.1 to 44.5 g. At the embryonic stage, body weight equals 0 g, and offspring have a body weight of from 0.1 to 10 g and a body length of from 5 mm to 4.5 cm. Adult individuals reach a body weight of from 20 to 45 g and a body length of from 9 to 13 cm.

The little swamp mouse inhabits an altitude from 100 m to 500 m above sea level, preferring Mediterranean forest with a summer dry and hot and a winter warm and rainy. The species is found in various landscapes, including land, terrestrial forests, terrestrial herbaceous areas and shrubs. In terms of climatic conditions, the little swamp mouse is adapted to cold steppe with dryness, a cold winter, an abundance of grass and a small number of trees, as well as to a very dry climate, a cold and almost dry climate, a summer with almost no rain and a hot climate with almost complete absence of precipitation.

The red-tailed mousesack is a nocturnal hunter that preys on insects and small animals, catching its food both on the ground and in trees using a strategy of active hunting and foraging. Its diet includes insects, spiders, small lizards, small mammals, and small reptiles, specifically beetles, flies, moths, mayflies, crayfish, ribbon worms, snails, leeches, bedbugs, grasshoppers, dragonflies, and caddisflies. The species obtains food through nocturnal searching and capturing prey with its teeth. Young red-tailed phascogales consume milk. The daily food requirement ranges from 5 grams to 15 grams.
Բազմացում
Red-tailed mousesacks inhabit terrestrial environments and develop exclusively on land, away from bodies of water; embryonic development lasts 5 days, and the female carries very small young in a pouch or mouth. A litter has 6 to 8 offspring, and reproduction occurs once per year. The interval between reproductive events is from 1 year to 1 year and 1 month. Young develop in a pouch or mouth on land, and eggs or young also develop in nests built on or near the ground, or high in the branches of shrubs or trees. Sexual reproduction is homogamous, always involving fertilization without generation changes; males frequently die after the breeding season. The female reaches maturity from 9 months and 1 week to 11 months.
