The primary food sources of the Eurasian water
shrew are
primarily invertebrates, as well as some smaller invertebrates.
This organism hunts primarily under water. Their main source(s)
of
food consists of snails,
worms, insects,
small fish (vertebrates), and amphibians such as frogs.
The Eurasian water shrew is also known to eat the larvae of
Caddis flies.
Because the Eurasian
water shrew has a high metabolic rate, it
needs to constantly eat all day and year round, which is why
shrews can be observed during the winter months, instead of in
hibernation. In terms of how much the Eurasian water shrew
needs on a daily basis, it eats its body weight in food.
