Which group of animals does the term lagomorphs include?

Lagomorphs refer specifically to a group of small to medium-sized mammals that are known for their distinctive characteristics, such as their long ears, short tails, and strong hind legs. The term "lagomorphs" includes animals belonging to the order Lagomorpha, which comprises rabbits, hares, and pika. These animals are well adapted for their environments, often exhibiting unique behaviors and reproductive strategies.

In contrast, the other groups mentioned do not fall under the definition of lagomorphs. Mice and rats belong to the order Rodentia, which encompasses different species with unique features distinct from those of lagomorphs. Deer and elk are part of the order Artiodactyla, which includes hooved mammals, and snakes and lizards belong to the class Reptilia, which is markedly different from mammals. Each of these groups has its own set of characteristics and biological classifications. Therefore, the correct choice pointing out rabbits and hares aligns with the scientific classification of lagomorphs.
