Following in the wake of the first great Triton beast to emerge from the ocean’s depths, these lesser creatures would still qualify as sea monsters if you found one washed up on the beach. steel shell crabs are so named because of their incredibly dense exoskeletons. In the first skirmishes between these mega crustaceans and G.U.A.R.D. forces, the crabs’ shells were virtually immune to all but the largest ordnance. Luckily, it was soon apparent that, like their larger counterparts, the steel shell crabs were more interested in fighting Earth’s invaders than anything native to the planet.

Slithering behind waves of crabs come the psi-eels. Human scientists have so far failed to capture a live specimen, so the full extent of their abilities is untested, but from battlefield readings it appears that they have mental capacities hitherto only seen in the extra-dimensional beasts assaulting the planet.
