The Andaman shrew or Andaman white-toothed shrew (Crocidura andamanensis) is a critically endangered species of mammal in the family Soricidae. It is endemic to the South Andaman Island of India. They are usually active by twilight or in the night and have specialized habitat requirements. Habitat loss due to selective logging, natural disasters such as tsunami and drastic weather change are thought to contribute to current population declines.
