Aquigrade - Water Colossus

My contest entry for the RIFT Create A Colossus Contest.

I LOVE this thing. I feel like I really stepped out of my comfort zone to make this little (GIANT) guy and I couldn't be more proud of him.

Some basic info that I made for him while I was designing him:
Name - Aquigrade (Ack-qwi-gray-d)
Plane - Water
Though it seemingly has few special sensory organs (such as ears, eyes, and nostrils) the Aquigrade can smell (and in a way see) the same way it breathes: through its amphibious skin that is constantly releasing and reabsorbing water as it inhales and exhales.
The Aquigrade also has two mouths. Its main mouth is obviously the larger one on its rear end, but below the opposable claws on its front is a hidden, lamprey-like mouth that works as a garbage disposal of sorts.
Unlike the antennae of insects and crustaceans, the Aquigrade's antennae atop its head actually serve no extrasensory purpose.

5 POINTS TO THE FIRST PERSON WHO CAN GUESS WHAT THIS CREATURE IS BASED OFF OF!!!

Edit: Congrats to for guessing right ^^
