The blue duiker is the smallest species in the Bovidae family, which includes antelopes, cattle, goats, sheep, and related animals. They are found in the forests of Central and Southern Africa. I fondly remember these small antelope strolling across our garden in Pennington, where I grew up. They are monogamous and thus always seen moving in pairs within their territory. They are primarily frugivorous, eating leaves, flowers, and occasionally insects.

The Etruscan shrew is the smallest shrew and one of the smallest mammals by mass. They are widely distributed in Southern Europe, North Africa, and Asia. Despite their small size, their metabolic rate is extremely high. They have to eat about 1.5-2 times their body weight in food daily. This species is also known for having one of the fastest heartbeats in the animal kingdom. Their heart can beat up to 1511 times per minute!
