Piranhasaurus

The Piranahasaurus is an unholy chimera of piranha and Utahraptor. It was created by the "Mad Scientist of the Moon" in her Moon-base to terrorize Earth-based governments for the industrial accidents that created Sharktypus.

Piranahasaurus is known by the epithet

 Deadly on land,
 Twice as deadly in the air
 Thrice as deadly in water.
