Cephadrome

From Monster Hunter - Wiki on Neoseeker

The Cephadrome is a Piscine that dwells in the sand and is able to zip around just under the surface. It is very similar to the water based wyvern, Plesioth. Its nickname is the Land Shark because while it is moving around it looks like a shark in the sand, with it's top fin exposed. An interesting fact to note is that the Cephadrome derives its name from the Greek word for head. The Cephadrome utilises sand attacks, as well as occasional body thrusts. One of the most annoying aspects of the Cephadrome is the fact that it stays underground, where it is very hard to attack. Whilst submerged, it often doesn't come out without the aid of a well-aimed sonic bomb or a carefully placed barrel bomb, or if timed very well, a charged hit from a Great Sword or Hammer. It is only found in the Desert.
