What are some adaptations of the water shrew to allow it to go into the water?

Water shrews have very dense, stiff hairs on coats. Their coats also contain ridges that help them to retain water when they are swimming. This air bubble that is created by the shrew’s fur coat allows for better buoyancy and allows them to move easily and faster through aquatic environments in search for food.

Do water shrews hibernate?

They do not hibernate; they remain active all through the year, diving for aquatic prey even in mid-winter. The fur is denser than in other shrews, efficiently insulating them against cold and wet.

Why are water shrews endangered?

Reasons for Being Threatened: The West Virginia water shrew appears to be restricted to a very limited range in Pennsylvania and population densities are low. Disturbances to their forest environments that result in warming or sediment in streams, or changes in pH, are likely to negatively affect the species.

Where does a water shrew live?

Most water shrews live in montane habitats and forage in clear, cold streams and small rivers. They use all four feet to swim, but most of the propulsive force comes from the hind feet.

What animal eats water shrew?

Water shrews dive and swim to escape from predators like garter snakes, hawks, owls and weasels.

How long can a shrew live without food?

Shrews need to consume 200 to 300% of their body weight in food each day in order to survive. A shrew must eat every 2 to 3 hours to achieve this goal. A shrew will starve if it goes without food for more than a few hours.

Are water shrews endangered?

Least Concern (Population stable)
Eurasian water shrew/Conservation status

How do you get a shrew out of your house?

If shrews are present inside your home, live trapping can be an effective control method. Choose a trap that’s small enough to conform to the shrew’s tiny size, and bait it with shrew favorites such as crisp bacon, peanut butter or hot dog slices.

Are water shrews poisonous?

Like many shrews, the water shrew has venomous saliva, making it one of the few venomous mammals, although it is not able to puncture the skin of large animals, nor that of humans.

Do water shrews bite?

The water shrew is quite unusual among mammals because it has a venomous bite. The poison in its saliva is strong enough to immobilise frogs and small fish. It can tackle prey up to 60 times heavier than itself, including newts, frogs, crustaceans and snails.

How long does a shrew live?

Etruscan shrew: 2 years
Eurasian water shrew: 3 years

What kind of habitat do water shrews live in?

Water shrews are common inhabitants of northern forests. As the name would suggest, water shrews are often found around streams and other aquatic habitats. Moist areas surrounded by heavy vegetation, logs and rocks are preferred. These animals are found in the following types of habitat.

Why are water shrews declining in the wild?

The loss and degradation of riparian habitat and increases in pollution and pesticides may be responsible for this speculated decline. The Environment Agency commissioned a Species Action Plan and Species Management Guidelines for the water shrew (Churchfield, 1997a,b) to clarify its status.

What does a water shrew do in a pond?

The water shrew is our largest shrew. As the name suggests, it lives almost entirely in wetland habitats, such as streams, ponds, fens and reedbeds. It spends much of its time hunting for invertebrates and even swimming underwater to catch caddisfly and mayfly larvae.

How does a water shrew build a nest?

Water shrews dig their own tunnels by digging with the fore feet and throwing out soil with their hind feet. New nests are built using their feet and legs to form a depression and the walls of the nest shaped with the snout. Water shrews are aggressive and fighting is common between them. Males and females are equally likely to fight.
