Tiger Jaws Succulent, aka Faucaria tigrina or Shark Jaws, is a slow-growing succulent native to the subtropical deserts of South Africa. These little cuties produce low rosettes of fleshy, triangular leaves lined with soft, spiny "teeth," which evolved to help the plant direct rainwater and dew down to its roots. If you have grown and Aloe or Haworthia before, a Tiger Jaw will be a breeze for you.
