Tracks of a hopping snowshoe hare in snow; rounder forefeet together, longer rear feet apart, forefeet together again. Snowshoe hares prefer branches, twigs, and small stems up to 0.25 inch (6.3 mm) diameter; larger stems are sometimes used in winter. [16] In Yukon, they normally eat fast-growing birches and willows, and avoid spruce.
Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.

Even though their swimming abilities [16] lack the speed to escape a pack of hunting dogs, swamp rabbits elude pursuers by lying still in the water surrounded by brush or plant debris with only their nose visible. [4] The species is hunted for fur, meat, and sport, and is the second-most commonly hunted rabbit in the United States. [7]
They can also feed on other aquatic or marsh plants such as centella, greenbrier vine, marsh pennywort, water hyacinth, wild potato, and amaryllis. [12] Marsh rabbits, like all rabbits, reingest their food, a practice known as coprophagy. [7] Rabbits excrete both hard and soft fecal pellets.
Strictly, it excludes the situation where the fetus is a hybrid of the carrier and another species, thereby excluding the possibility that the carrier is the biological mother of the offspring. Strictly, interspecific pregnancy is also distinguished from endoparasitism , where parasite offspring grow inside the organism of another species, not ...

Hares are generally larger than rabbits, with longer ears, and have black markings on their fur. Hares, like all leporids, have jointed, or kinetic, skulls, unique among mammals. They have 48 chromosomes, [10] while rabbits have 44. [11] Hares have not been domesticated, while some rabbits are raised for food and kept as pets.
