## Interesting facts

- Despite its size, it needs to eat 80% of its body weight every single day!
- Eurasian Water Shrews can hunt and even catch prey larger than themselves!
- Its tiny heart can beat an amazing 1,200 times per minute when active!
- They use simple clicks for navigation, like a very basic form of echolocation!

## Special abilities

## Traits

- [Webbed Feet](https://www.snappit.app/explore/traits/webbed-feet): Characterized by having toes connected by a membrane, typically aiding in swimming.
- [Solitary](https://www.snappit.app/explore/traits/solitary): Solitary animals live alone for most of their lives, only interacting with others for mating or parental care.
- [Burrowing](https://www.snappit.app/explore/traits/burrowing): Burrowing animals dig tunnels and chambers in the ground, using these subterranean structures for shelter, hunting, or breeding.
- [Insectivorous](https://www.snappit.app/explore/traits/insectivorous): This trait identifies organisms whose diet primarily consists of insects and other small invertebrates.
- [Piscivorous](https://www.snappit.app/explore/traits/piscivorous): Piscivorous organisms are animals that primarily subsist on a diet of fish.
- [Thermoregulating](https://www.snappit.app/explore/traits/thermoregulating): Thermoregulating organisms maintain a stable internal body temperature despite fluctuations in the external environment.
- [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years.
- [Wetland](https://www.snappit.app/explore/traits/wetland): This habitat trait identifies species found in wetlands, which are areas of land saturated with water, either permanently or seasonally, including marshes, swamps, and bogs.
- [Regenerative](https://www.snappit.app/explore/traits/regenerative): Regenerative organisms possess the ability to regrow lost or damaged body parts, tissues, or organs.
- [Nocturnal](https://www.snappit.app/explore/traits/nocturnal): Nocturnal animals are primarily active during the nighttime hours, typically resting or sleeping during the day.
- [Venomous](https://www.snappit.app/explore/traits/venomous): Venomous organisms produce toxins that are injected into another animal, typically through a bite or sting.
