The river glider split from the vegehopper. They adapted better to land live; while their gills are still functioning, their lungs became more effective, making longer land stays possible. Another distinctive adaption are their lip teeth that work similar to a Earth'smollusk's radula, enabling the river glider to feed on harder tissue than its ancestor, like the mavrophytes' main bodies and terrestrial plants near the river, hence they are no food concurrence for their ancestors. Their more terrestrial lifestyle led to fused hind tentacles with broad, foot-like tips for more powerful leaps; in combination with its enlarged leaf fins this creature is able to glide, an effective way to escape predators.
