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

Central and eastern North America, from southern Saskatchewan to Atlantic Canada, south to northern Arkansas and Georgia1

Tuis

It lives in grasslands, old fields, fencerows, marshy areas, and deciduous and coniferous forests, and it also uses household gardens. It prefers places that are moist, with leaf litter or thick plant cover. It tunnels below ground, through leaf litter, or at the boundary between snow and ground.1

Wat eet dit?

It is mostly carnivorous and prefers insects such as beetles, earthworms, voles, snails, and other shrews. It also eats salamanders, frogs, snakes, birds, and mice, and it mostly hunts within a few hours after sunset. It often hoards food, storing about 87% of the prey it catches.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

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

Wat doen dit as dit bang is?

Its scent glands produce a musky odour that deters mammalian carnivores.1

As dit byt

Was die wond goed en kry mediese hulp.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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
