Actually it kinda makes sense with Tetsukaburu.Tetsukaburu seems to be based off Poison Dart/Arrow Frogs and Horned Frogs(and some prehistoric amphibians),which all of them aren't good swimmers and spend most of their life on land but,only really going to the water to lay eggs are bring their young food or,to a source of water.For me,Tetsukaburu hides in the small ponds or streams to ambush any prey that comes to close to the waters edge.

Also it kinda seems like Capcom has been hinting to Lagiacrus,returning in this game.
