Sand Trappers

While the Sand Trappers of Mars -the smaller cousins of the Leviathan- surely look dangerous, one might think that they can be easily avoided since they are immobile... Wrong. These monsters wait under the sand until prey comes by, only to suddenly appear and grab it with its tentacles. And should the prey try to resist, it spits a paralyzing venom at it. It can only effectively killed in a group.

Sadly, they can appear anywhere on the surface.
