This giant snail lives deep beneath water near volcanic vents. It eats anything it can catch and has a toxin that makes catching things easier.
This was made for day 29 of Mer-May.
Edit: I did not know this when I created and posted this creature, but it turns out that May 29 is National Snail Day here in the US. I find this coincidence quite amusing.
