The northern short-tailed shrew is a small, very active mammal that lives in eastern and central North America. It is one of the few venomous mammals, and it uses venom in its saliva to paralyse the animals it hunts. It is also a voracious eater that can eat up to three times its own weight in food each day.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

Its saliva contains a kallikrein-like protease, a toxin that paralyses and subdues prey. The toxin is strong enough to kill small animals, including some somewhat larger than the shrew itself. In people, it causes painful bites when they handle the shrew.1

Its bites are painful to people who try to handle it.1

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

jakin beharrekoa

Datuak

It is one of the few venomous mammals, and its saliva is used to subdue prey.1

It can eat up to three times its own weight in food each day.1

It is thought to have a poor sense of smell and very limited vision, so it uses echolocation and a fine sense of touch instead.1

Its winter food intake is 43% higher than in summer, because it must work harder to keep its body warm.1

Its nests can be up to 20 cm across and lined with leaves or vole fur, and its waste is kept in a separate latrine area.1
