This is a list of the mammal species recorded in Canada.There are approximately 200 mammal species in Canada. [1] Its large territorial size consist of fifteen terrestrial and five marine ecozones, ranging from oceanic coasts, to mountains to plains to urban housing, mean that Canada can harbour a great variety of species, including nearly half of the known cetaceans.

True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.).

Most Ouessant are black or dark brown in color, but white individuals do occur. The rams have relatively large horns, and ewes are polled. The Ouessant existed exclusively on its home island until the beginning of the 20th century, and is still a rare breed today. Ewes rarely produce twins, and the breed is primarily used for wool production.
A similar use of posterodorsal horns has been indicated to decrease predation in horned lizards. As the horns grow taller through evolutionary time, [2] they also become more posteriorly positioned and the height of the occipital plate increases, increasing the leverage for lifting them. By positioning the horns more posteriorly, the output ...

The greater short-horned lizard is often mistaken for its close relative the pygmy short-horned lizard (Phrynosoma douglasii), which has the same basic body type consisting of small pointed scales around the head and back. [3] Until recent mitochondrial DNA evidence, P. hernandesi was considered to be the same species as P. douglasii.
