COW - Comet Rider

The Comet Rider is a small parasite that uses it's flat, tight body to hug the surfaces of comets to combat the vacuum of space. It slowly scuttles across the rock to keep contact with the nearest star, absorbing rays through it's webbing and collecting stray particles of matter (as well as some elements of radiation) with the hairs on two long appendages extending from the back. Periodically, small spores are released from two porous bulbs connected to these appendages, which spread and eventually seed other satellites.
