Faucaria felina - Tiger Jaws
Leaves shaped like jaws with teeth. Don't worry they are soft :)
Your plant will be similar to the one in the photos.
Ships in a plastic pot with soil.
Not as picky about soil, store bought succulent mix is good, especially if you add some sand or perlite/pumice to make it drain a little better
Part sun, protect from hot afternoon sun
Let dry between watering, water deeply
