💡 Interesting Facts
1
Common shrews eat 80–90 % of their body weight every day and are fiercely territorial — fights often end in death. In winter their skull actually shrinks to save energy. They produce high-pitched squeaks that are almost ultrasonic.
2
They are one of the most abundant small mammals in the UK yet very few people ever see them alive.
