In polygynous species, males will try to monopolize and mate with multiple ladies. Just like monogamy, polygyny in rodents can are available in two sorts; defense and non-protection.

animals that use metabolically generated heat to regulate body temperature independently of ambient temperature.
The incisors have enamel on website the outside and exposed dentine on the inside, so that they self-sharpen in the course of gnawing. Rodents deficiency canines and very first premolars, which makes a space in between their incisors and their grinding enamel.
