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

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Če ugrizne

Rano dobro umij in poišči zdravniško pomoč.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

vredno vedeti

Dejstva

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
