[10] 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. The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew is the smallest known mammal by mass, weighing only about 1.8 grams (0.063 oz) on average (The bumblebee bat is regarded as the smallest mammal by skull size). [10], The largest threat to Etruscan shrews originates from human activities, particularly destruction of their nesting grounds and habitats as a result of farming. [9] It kills large prey by a bite to the head and eats it immediately, but takes small insects back to its nest. [5][6][7] When hunting, it relies mostly on its sense of touch rather than vision, and may even run into its food at night. [3] This induces heating, with the rate up to 0.83   °C/min, which is among the highest values recorded in mammals; the heart rate increases exponentially with time from 100 to 800—1200  beats/min, and the respiratory rate rises linearly from 50 to 600—800  beats/min. The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/s) and a relatively large heart muscle mass, 1.2% of body weight. Areas where open terrain such as grasslands and scrub meet deciduous forests are usually inhabited. [4], Etruscan shrews mate primarily from March to October, though they can be pregnant at any time of the year. Behav. The fur color on the back and sides is pale brown, but is light gray on the stomach. The ears are relatively large and protuberant. The Etruscan shrew, also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew, is the smallest known mammal by mass, weighing only about 1.8 grams on average. [6] Near the mouth grow a dense array of short whiskers, which the shrew actively uses to search for prey, especially in the night. [3][4][5][6][7] (The bumblebee bat is regarded as the smallest mammal by skull size and body length.[3][8]). [5] Major predators are birds of prey, especially owls.[6][10]. 1988. [7]Dimorphism in body features between males and females is absent. The hiding periods are short, and typically last less than half an hour. Recovery from this state is accompanied by shivering with the frequency of about 3500  min−1 (58  s−1). It weighs only around 1.8 grams (0.063 oz) on average. While not completely nocturnal, the Etruscan Shrew is active during the night and usually stay near their nest during the day. The gestation period is 27—28 days, and they have 2—6 cubs per litter.

In Asia, it was observed in Afghanistan, Azerbaijan, Bhutan, China (Gengma County only), Burma, Georgia, India, Iran, Iraq, Kazakhstan, Laos, Malaysia (Malaysian part of Borneo island), Nepal, Pakistan, Philippines, Sri Lanka, Tajikistan, Thailand, Turkey, Turkmenistan and Vietnam. [2] It is poorly adapted to digging burrows, so it arranges its nests in various natural shelters, crevices and others' uninhabited burrows.

The Etruscan Shrew is a species of shrew, small mole-like animals, and holds the record for being the smallest mammal in the world by mass. After their eyes open at 14 to 16 days old, they mature quickly. The Etruscan shrew has a slender (not truncated) body, with a length between excluding the tail, which adds another 2.4 to 3.2 cm. Nowak, R. 1990. [9] It colonizes riparian thickets along the banks of lakes and rivers, as well as human-cultivated areas (abandoned gardens, orchards, vineyards, olive groves and edges of fields). The Etruscan shrew is the smallest known mammal by mass. Sandy, (5.4 cm.) The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew is the smallest known mammal by mass, weighing only about 1.8 grams (0.063 oz) on average (The bumblebee bat is regarded as the smallest mammal by skull size and body length). Areas where open terrain such as grasslands and scrub meet deciduous forests are usually inhabited. [2], The shrew also occurs in North Africa (Algeria, Egypt, Libya, Morocco, Tunisia) and around Arabian Peninsula (Bahrain, Israel, Jordan, Lebanon, Oman, Syria, and Yemen including Socotra). [2][9] Cubs are born naked and blind, weighing only 0.2  g (0.0071  oz). Reader Michael Lisieski suggested to me about a week ago a couple of cool animals to write about, including the Etruscan Shrew which is an adorable little creature. [9], Because of its high ratio of surface area to body volume, the Etruscan shrew has an extremely fast metabolism and must eat 1.5–2.0 times its body weight in food per day. You could also do it yourself at any point in time. The mother usually moves the young when they are 9 to 10 days old and if disturbed leads them by caravanning them to a new location. Listen to the audio pronunciation of Etruscan Shrew on pronouncekiwi. [9] The shrew usually has 30 teeth, but the 4th upper intermediate tooth is very small (rudimentary), and is absent in some individuals. [5][6][7] When hunting, the Etruscan shrew mostly relies on its sense of touch rather than vision, and may even run into its food at night. 10.2305/IUCN.UK.2017-2.RLTS.T90389138A22288134.en, "Rates of rewarming, heart and respiratory rates and their significance for oxygen transport during arousal from torpor in the smallest mammal, the Etruscan shrew Suncus etruscus", Suncus etruscus. [3] In Southern Europe, it has been found in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, France, North Macedonia, Malta, Montenegro, Greece, Italy, Portugal, Slovenia, Spain, and Turkey, with unconfirmed reports in Andorra, Gibraltar and Monaco; it has been introduced by humans to some European islands, such as Canary Islands.
