Reagan was just the average marine biology intern, but he never expected to be drawn into a portal and wake up as one of the creatures who dwells in the ocean. Not only is this seemingly new world confusing and filled to the brim with predatory monsters, but it seems to have a system like an RPG! But Reagan's hopes of incredible powers are quickly destroyed when he makes the discovery that he is a custacean, and crustaceans are the only monsters who can't evolve or get abilities as they level up, the only thing they get is bigger.

PS. this is my first story, i accept criticism.
