Baleens also do have some regional variations, populations who've adapted to their environments compared to their desert cousins.

The Shattered continent baleens are isolated from their Horseshoe continent cousins. Over time, their more volcanic environment has driven them to develop more tough skin and darker colors.

Tundra Baleen have adapted by bulking up and getting more "fuzz" on their body. They've mostly abandoned fishing with their arms and use specialized nets to catch the shrimps and other small marine life they subsist upon.

Finally, the mangrove baleens have a taller, more lanky subset who live in the hotter parts of the region. They tend to spend most of their time wading through the shallows of the mangroves, and their longer legs help keep their bodies away from dangerous roots and critters.
