The competition really heated up once this photo of a Matamata Turtle surfaced. Translated from Spanish, matamata means "I kill, I kill".

You surely are killing our eyes! Amongst the major standout features of this hideous creature, is the head and neck, which is large, flat and covered with numerous protuberances, warts, and ridges. It has an extremely wide mouth, and very small eyes, which is situated near its long snout.

Sadly, the limbs of the Matamata Turtle are poorly developed...so is the face, the slimy body, etc...
