Dark Swarmer

The dark swarmer has adapted to the deep sea. It doesn't feed via photosynthesis anymore, but it swallows all organic matter, which sinks from the ocean surface to the ground. At each end of its tentacles is a glowing organ. The dark swarmer spreads the end of the tentacles as much as it can, in order to look bigger and therefore to scare off predators. At night, the dark swarmers swim to the surface of the water, where there is more organic matter to swallow. Their photosynthesis has adapted to the light the tentacles emit, so that the dark swarmer can reuse some of the energy.
