Pudgy Nailfin

The pudgy nailfin replaced its ancestor the quilled nailfin. It doubled in size and gained thicker blubber to keep warm. Its stout feature help retain heat in the polar waters. It flippers have fused together to better paddle through the water. Their black backs help them warm up faster when sunning themselves on land.

They have become herbivores since it takes less energy than hunting the very fast gilltails. They use their "wooden" "pseudo-beaks" to rip off or crush hard flora such as the rubbery chunky plyent or the well armored thornshell. They can also use their beaks to break through ice sheets when they need to come up for air.

They live in large groups that consist of 6-14 members. During the day they will spend much of the time on land sunning themselves. Then at night they will feed on aquatic flora like the crestgrove. Like their ancestor they have sexual dimorphism. Males have a green sail and the females have a gray sail. Males will fight over females by wrestling on land and even biting each other with their "pseudo-beaks".
