Sandbelching Meerslug

The Sandbelching Meerslug is a large worm-like invertebrate that was found by Captain Charlie during his PNF-404 expedition. It is the second largest creature found on the planet, only behind the Quaggled Mireclops in pure size, though it seems to rival it in length.

Appearance
This gigantic creature is amphibious in nature, but not in similar vein to true amphibious creatures as it doesn't venture into water, but more rather remains underground in moist areas, with its skin being primitive "warty" skin. This makes it more akin to amphibians such as earth toads rather than frogs in comparison.

Its body is fairly bulbous along the lower half, with the upper body slim to extend out of the ground to scope out its environment. Its back is covered in spike-like protrusions, and its head is similar to that of a lamprey: a round mouth at the very front of the body with very small eyes and rows of sharp teeth within its jaws. It also has small fluff-like organs just underneath its eyes, along with a small set of gills behind them. This possibly could be a placeholder for its ancestors, which possibly were fully aquatic prior to this stage.

Behavior
Sandbelching Meerslugs are subterranean ambush predators. These giant creature spend much of their time underground, but upon sensing prey above ground it will burst out in an attempt to eat whatever it found. Its large size means that it has a wide variety of food sources. One special strategy it will employ is that it can alter soft earth into a cone-like divot, leaving a pit for animals to fall into with its open jaws at the very bottom to bite and capture prey.

What makes this creature especially intriguing is that it can also shoot out sand balls at threats. This, accompanied by the spikes on its back are often signs of protection against predators. What predator such a large creature could be trying to protect against remains to be said.
