World’s Smallest Known Mammal (by Mass) - ETRUSCAN SHREW Also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew Location: in the belt between 10° and 30°N latitude stretching from Europe and North Africa up to Malaysia. Status: Least Concern, relatively rare and are endangered in some countries. Facts: The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/second) and a relatively large heart muscle mass, 1.2% of body weight. Etruscan shrew have an extremely fast metabolism and have to eat 1.5–2 times their body weight in food per day. They feed up to 25 times per day They tend to groom themselves constantly when not eating and are always moving when awake and not hiding Cubs are born naked and blind, but quickly develop, becoming independent and sexually mature at 3–4 weeks of age. It is poorly adapted to digging burrows and therefore arranges its nests in various natural shelters, crevices and others uninhabited burrows. A clicking sound is heard when these shrews are moving, which ceases when they rest.  The shrews are more active during the night when they make long trips; during the day, they stay near the nest or in a hiding place. —- Fact Source: http://en.wikipedia.org/wiki/Etruscan_shrew
