Where the name comes from

Ceratophrys is Greek for “horned toad”, from kéras, horn, and ophrýs, brow: the pointed folds above the eyes. Ornata, Latin, “decorated”, for the vivid colours. In English it is known as the Pacman frog, for the enormous mouth and voracious appetite: it is almost all head and mouth.

Characteristics

  • 01

    The mouth is nearly as wide as the body: it can swallow prey as large as itself.

  • 02

    It lies motionless half-buried in mud, ambushing whatever passes.

  • 03

    It has sharp “teeth” on the jaw to hold prey that struggles.

What sets it apart

The horned frog is all appetite: it attacks anything that moves and more or less fits in its mouth, including prey as large as itself, and sometimes chokes to death trying to swallow too big a mouthful. It is so voracious that the young are cannibals. It even has a sort of teeth: two pointed bony projections on the lower jaw, unique among frogs, with which it grips and does not let go. An amphibian that is, in practice, a trap with eyes.
