Firstly, it would be impossible for plesioth to rely on breathing through its skin. This tecnique is used be only small animals, and would never work for something the size of a dog, never mind a 30m water wyvern. Thankfully they have lungs as well.

I am not surprised they are faster than leviathans. MH3U's plessy goes like a missile. No chance of keeping up with that. It must be thier main defense, being able to outrun any predator. Even at cruising speed it is just as fast as a lagiacrus swimming as fast as possible.

Just a quick question, what are those scources that you get this info from? Is it official?
