Faucaria Tigrina

In The Greenhouse, No One Can Hear You Scream

They say that life imitates art but perhaps in this case it is the other way around. This is Faucaria tigrina or the Tiger's Jaw - a succulent plant found in South Africa.

Yet caught at the right angle the plant does not resemble so much the jaw of a tiger as that of an altogether alien creature, featured in a number of movies starring Sigourney Weaver et al.
