Scythid

Scythids are large, leech-like creatures native to the planet Pandora. They have fleshy appendages on there sides that allow them to jump and fly. Scythids are fast, usually low to the ground, and always attack in groups. They are generally not regarded as dangerous enemies, although they can offer some element of surprise with their mob attacks and tendency to remain hidden until potential prey ventures close. Other than the small Scythid Crawler, Scythids are not particularly fragile. It is unknown if Scythids went extinct after the opening of the Vault, although, as none have been seen since, it is safe to assume this to be true.
