It’s about the shrew (Suncus etruscus) with a light weight of so only 2 grams and a body length of the body plus head, not including its tail, of only 3 to 5 cm. Its tail can measure from 1 to 2 cm. For that reason you can say that it is the smallest mammal in the world.
shrew’s head It is large compared to the size of the body, with its ear pinnae prominently protruding from the hair, while the snout is very sharp and is provided with large vibrissae (whiskers), which play an important tactile role. The eyes are tiny and almost non-functional. The shrew can live up to 18 weeks and in captivity up to 26 weeks, its gestation lasts from 27 to 28 days.
the shrew It is a species that comes from central and northern Africa, from where it spread throughout Mediterranean Europe, including its islands, although it is missing from the Balearic Islands, adapting to Mediterranean vegetation and crops, where it finds its optimum. It does not rise above 1,000 meters of altitude, preferring open and sunny land, which contains a minimum vegetation cover.
the shrew it is active all year and during practically the whole day, due to its high metabolism so that it needs to consume food equivalent to more than half of its body weight daily, even when it is during the night when it reaches its greatest activity, with alternating periods of activity and rest , in which it enters a deep torpor that reduces its energy consumption, even when it is at night when it reaches its greatest activity, for which reason it is fundamentally a victim of nocturnal birds of prey.
Although sociable, the shrew usually faces tough battles with its peers, with very serious consequences in many cases. In winter it is more aggressive than in the rest of the year, it is estimated that due to competition for food, which is mainly made up of insects, and within these by beetles, it also consumes worms, arachnids, molluscs such as snails, or myriapods like the centipede.
