Riverent

After the beak swent and woodland swent evolved, the remaining swent within the Gec River and Gec Lake were replaced by its descendant, the riverent. To adapt even further to its aquatic home, its wings have become strong paddles that allow it to swim faster and leap out of the water. Its tail is now used like a rudder to help it turn when it needs to go a different direction. Its eyes have moved to the top, which allows it to see above the water while it swims in the water. Its beak has regenerated and it is full of baleen that filter out tiny microbes. It has also adapted by using orange photosynthesis, which means it only absorbs blue light.

Another extreme change it went through is that it has become a sexual hermaphrodite, which allows it to spread and share its genetics with other riverents. It has also lost its back legs due to them having no use, but it has kept its front legs, which the offspring use to cling onto their parents.
