Porplent

The Porplent split from the Sealplent. It now lives in the cold southern polar coast. They only eat Polar Krillpede, which is very abundant there. Their mouth has evolved baleen and can now filter them out of the water. Its leaf-fins have grown bigger and front feet smaller. Its tail and 2 back legs have merged into a flat manatee-like tail fluke. Also its butt-nostril has continued to evolved into larger a dorsal fin / snorkel so it can breathe. Its neck has evolved a large sack in which it can hold the water and food until the water is pushed out of the baleen. Unlike their ancestors they do not come up on land anymore and are fully aquatic.
