Dust bug

The dust devil life form is a being of unknown origin that inhabits a desert planet in the galaxy through which Destiny is currently travelling.

It was the first alien being that the Destiny Expedition encountered after boarding the ship, and Lt. Matthew Scott was the only known person to see it. He tested its intelligence and appetite by pouring water into the sand and watching while it moved to that same spot. It also may have been responsible for Scott's hallucination and memory of the priest who raised him.

Later, as Scott lay unconscious next to a dry lake bed, the life form seemed to burrow into the sand near Scott's face and release water, waking him.

A small group manages to sneak aboard Destiny where it quickly consumes half of the ship's water supply of 80 thousand litres. After lethally attacking Corporal Gorman it is successfully lured into a water barrel where it would later escape after being thrown out onto the Hoth planet.
