Eastern Lesser White-toothed Shrew (Crocidura suaveolens) lives in temperate forests across Europe and Asia. Its conservation status is Least Concern.
Fascinating facts about the Eastern Lesser White-toothed Shrew
- When a Scilly shrew wanders onto a beach, it swaps its usual insect diet for a near-exclusive feast on amphipods, tiny crustaceans that scuttle across sand. Most white-toothed shrews hunt insects, spiders, worms, and even small rodents, but the beach-dwelling Scilly shrews have rewired their foraging to match the salty shoreline. This dietary switch highlights the species' flexibility.
- A female lesser white-toothed shrew and her young can form a "caravan" while hunting, each clutching the tail of the one ahead. Imagine a line of tiny mammals, moving together through scrub or garden underbrush. This behavior keeps the vulnerable pups safe from predators and ensures they stay close to the mother's food sources, illustrating a simple yet effective social strategy in a species that otherwise lives a solitary life.
- Archaeological digs on the Isles of Scilly have uncovered shrew bones dating back to the Bronze Age, meaning these tiny mammals have been on the islands. Their long-term presence suggests they survived the breakup of the islands from the mainland and possibly even rode on early human ships.
- In July 1924, a naturalist named W N Blair discovered an unknown shrew on Gugh, one of the Scilly islands, and sent it to the British Museum where it became the type specimen for the local population. Ten years earlier, another unknown rodent was sent from Old Town, St Mary's, to a leading rodent collector. These early 20th-century finds underscore how even well-studied regions can hide undiscovered mammals, reminding us that careful observation still yields new scientific treasures.
- Those islands are so isolated that the shrews there form a distinct group, sometimes called the Scilly shrew, with skull and tooth sizes that sit between those of mainland and Channel Island relatives.
