This is where you'll find all the dinosaurs that have an advantage in water terrains. Use this category to construct decks for water terrains. (Hint if you favor or build a Water Terrain deck then using a Marine Reptile would extremely help and increase your chances of winning. Know that Marine Reptiles have a strong disavantage in the Mountain Terrains. Also out of all the dinos in Dino Dominion Marine Reptiles are the only ones who family, or class have no disadvantage in the Water Terrains.)
