Ohb

The Ohbs are a non-sapient species of metal-eating slug-like creatures which inhabit an unnamed planet. They are hunted as food by the Queegs.

Biology
Ohbs are large slug-like invertebrates, without bones, mouth or limbs, which feed on metal by absorbing it through their skin. They have concentric rings on the underside of their bodies, similar to some snakes and worms, and a pair of antennae on their heads. At the base of the antennae, they have numerous wart-like knobs. They inhabit wastelands devoid of vegetation, where natural sources of metal can be found. Despite being limbless, they are capable of leaping.

When Ohbs locate metal, their skin shines with a glowing network of capillaries, and their antennae shiver to signal the location of the food to the others.
