Dark Swarmer

The Dark Swarmer adapted to the deepsea. It doesn't feed on photosynthesis anymore, but it swallows all organic matter, which sinks from the surface of the sea 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, to look bigger and therefore to scare off predators. At night the Dark Swarmers swim to the surface of the watter, because there is more organic matter they can swallow. Their photosynthesis is adapted to the light the tentacles emerge, so that the Dark Swarmer can reuse some of the energy.
