Water Wyverns are a type of Flying Wyvern that has adapted to living in the water. This includes both Piscine Wyvern and Psuedowyvern-type monsters. Rexutaros for example, is a Psuedowyvern-type Flying Wyvern when on land, but completely changes its posture and attacks when submerged. This may seems confusing, but oncce his page is up, it should be easier to understand.

Note that Plesioth will remain a Piscine Wyvern.
