The Lesser white-toothed shrew (Crocidura suaveolens) is not found on mainland Britain.  It is, however, present in the Channel Islands, on Jersey and Sark, as well as being found in Scilly; here it is thought to be represented by a subspecies known as the "Scilly shrew" (Crocidura suaveolens cassiteridum).

It is believed to have originally been introduced to Scilly and has since evolved into a new subspecies, endemic to our Islands.

The "Scilly Shrew" is our smallest, and possibly cutest, mammal.

The "Scilly Shrew" is insectivorous (eating beetles, worms and sandhoppers) and can often be heard, if not seen, around the coast as they emit a soft, continuous twittering while foraging or exploring.  If startled or alarmed they can produce a sharp squeak.
