Mammals have a seemingly unique ability to gain the attention of all who encounter them, something that few other animal groups are capable of. Perhaps it is the cuddly appearance of some species, the size and strength of others, or the grace that they display when they move quickly. But more likely it is the fact that we too are mammals; We share all of the diagnostic traits of this diverse group, and yet there is such a great diversity of forms, shapes, and functions that all of these traits are packaged into. Mammals are truly diverse and masterfully adapted to their specific niches, so it is no wonder that they stir such fascination.
