Common Shrew vs Hero Shrew: common questions
What makes the hero shrew's spine so unusual?
This species has an interlocking, girder-like backbone so strong that a grown man can stand on the animal without harming it, an anatomy found in no other mammal, a feature the common shrew and virtually every other mammal entirely lacks.
Is the common shrew as physically unusual as the hero shrew?
No, the common shrew lives a comparatively ordinary shrew existence defined mainly by an extremely high metabolism and the need to eat close to its own body weight daily, without the extraordinary skeletal reinforcement that makes the hero shrew unique among all mammals.
Do the common shrew and hero shrew live in the same region?
No, the common shrew is native to grassland and forest habitat across most of Europe, while the hero shrew is native to rainforest habitat in Central Africa, meaning the two species occupy entirely different continents and habitat types.
