Wriggleback

The wriggleback is a hybrid of the oddech and nogoddech and replaced both ancestors. With few flora in the water and frequent stagant water the wriggleback used its ancestor's adaptions of getting oxygen directly from the air. As a result allow it to spend more time out of the water. However their intake siphon was in a precarious location for it to move around on its belly. Sure it could close it up to protect it from breathing in mud but if it was not careful it could sit on its belly too long and suffocate. A solution to this problem of suffocation outside of the water was solved by a behavioral change. Rather than wriggling around on their bellies they wriggle around on their backs. This allowed their intake siphon to become unobstructed and even put less weight on their chests when breathing. Soon enough they lost most of their back fins ad belly fins to better slip across the riverbanks. Now they swim right side up and go on land on their backs. Their strong fins are now scooped shaped in order help them flip over when coming to land. The back fins also help sheath the tail gills from getting dirty outside the water. They are golden in color to blend in with Darwin's golden soil. Like all gilltails they are cold blooded and move slowly when cold. They can now sun themselves on the river banks to get a boost of energy. They are primary ambush predators who supplement their diet with flora. They will wait at the rivers edge or in shallow pools for prey to pass by and snatch up. These strikes can be very comical if they leap out too far and have to flip on their backs in order to wriggle back to the water. They will attempt to hold their prey down and drown them. This can be very dangerous especially if its prey has spikes or sharp mandibles. If their prey are not drowned quickly they will let go in order to keep from getting too injured. Like their ancestor they are quite territorial and will fight over the best ambushing pools. They will typically cover themselves in mud to help keep from loosing moisture out of the water. Despite being able to leave the water they spawn in the river and not in the riparian zone. This gives their offspring a chance to feed on aquatic prey or flora before they leave the water for bigger prey.
