The Eurasian water shrew is a small, dark mammal that lives close to fresh water across northern Europe and Asia. It is one of the few venomous mammals, and it uses its venom to paralyse the prey it catches in the water.1

Leef in

Northern Europe (except Iceland, Ireland, some Mediterranean islands and the Balkans) and northern Asia, from western Siberia to North Korea1

Europa, Asië

Tuis

It lives close to fresh water, in and around ditches, streams, ponds, watercress beds, fish ponds, damp meadows and rough bushy ground next to water. It rarely strays far from water.1

Lengte

10 cm (3,9 in)1

Gewig

15 g tot 19 g (0,5 oz tot 0,7 oz)1

Topspoed

omtrent 4 km/h (2,5 mph)

Op land, rowwe skatting

Wat eet dit?

It mostly catches aquatic prey while swimming, including freshwater snails, aquatic insects, small fish, frogs, newts and small rodents. On land it eats invertebrates such as beetle and fly larvae, worms and millipedes.1

Hoe om dit te herken

Short, dark greyish-black fur on the head, back and sides1
Dirty white underparts, sharply separated from the darker back1
A white spot just behind the eye, and often another near the small ear1
Black nose and a long, tapering snout1

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 neurotoxic venom, which attacks the nerves. It delivers this venom at the base of the skull of its prey, and the venom paralyses prey even when the prey is larger than the shrew. Tests on field voles showed the venom is lethal at a minimum dose of 15 mg per kg of body weight.1

Hoe gevaarlik is dit vir mense?

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

Hantaviruses have been detected in shrews in Hungary and Poland, which raises public health concerns, although how the virus spreads is largely unknown.1

Wat doen dit as dit bang is?

Its venom is thought to immobilise organisms that may threaten it.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. Its venom comes from glands at the base of its lower front teeth, and grooves along the teeth channel the venom into the bite.1

Its teeth are tipped with red because of deposits of iron, which harden the enamel of the tips.1

It can dive up to two metres underwater and stay under for about twenty seconds before it must surface to breathe.1

Its short fur holds air, so its skin stays dry while it swims.1

It has a home range of about 500 square metres, but when foraging on land it can travel up to 3 km.1
