Etruscan shrews prefer living in warm and damp climates.

Most are located between 10° and 30° latitude in the northern hemisphere, in Southern Europe, Northern Africa, and parts of Southern Asia.

8. What is the habitat of the Etruscan shrew?

Etruscan shrews aren’t very good at digging, so they like making their nests in natural shelters like rock crevices.

If another animal has vacated their burrow, an Etruscan shrew will take advantage of the situation and move itself in.

You can also find them under shrubs, as they provide both a damp environment and a place to hide from predators.

9. What does an Etruscan shrew eat?

Because they have a very high metabolism, Etruscan shrews have a ferocious appetite. Each day they eat 1.5-2 times their own weight!

They feed mostly on insects and can take down prey equal to their own size. Grasshoppers are their favorite.

Earthworms and larvae are also on the menu. Sometimes they will feed on young lizards, amphibians, and rodents. They sure are hungry little things.

10. What is the heart rate of an Etruscan shrew?

Shrews are jittery and almost always moving. Their heart rate reflects this level of activity, beating at up to 1511 beats a minute. That works out to be about 25 beats a second.

A human heart, by comparison, beats around 60-100 times a minute (while at rest).

11. What are baby shrews called?

Baby shrews are called cubs. There are usually 2-6 cubs per litter. Etruscan shrews are born blind and naked.

If mama shrew has to relocate the babies, they will form a train, with each cub biting the tail of the cub in front of them.
