Leafed Swarmer

After the other swarmers went extinct, the swarmers of the global glacial were able to diversify back into the oceans. An off-shot of the mini swarmer, the leafed swarmer has adapted to life in Jujubee. their main adaptation is a giant leaf like growth that grows on their backs. As larvae they are sedentary, burrowing themselves into the nutrient rich sand with only their eyes and leaves sticking out, providing extra energy to grow with that would otherwise be used for movement. If they sense danger, they quickly dart away and rebury themselves. Their leaves slowly atrophy as they grow, until they reach adulthood when they leave the sea floor permanently.
