SHREW
DESCRIPTION
Shrews are small, mouse-like mammals characterized by their elongated snouts and small eyes. They have dense fur that can vary in color from brown to gray, and their size typically ranges from 3 to 6 inches in length. Shrews are known for their high metabolism and are often active foraging for food, which they need to sustain their energy levels.
FUN FACTS
- Shrews have a unique ability to produce venom, which they use to subdue their prey
- This venom can paralyze small animals, allowing shrews to store them alive for later consumption
- | Despite their small size, shrews are known to be fierce hunters and can take down prey much larger than themselves, showcasing their aggressive nature and high energy levels
