Acid Spit (Ex)

Once per round as a standard action, the planetoid beetle can spit acid as a ranged attack that has the Line“>line property and a range of 60 feet.

Break Objects (Ex)

When attacking an object, a planetoid beetle treats that object’s hardness as 10 lower.

Consume Objects (Ex)

A planetoid beetle can eat objects with a hardness of 10 or lower. It deals 4 damage per minute to an object it’s consuming. It is sated and stops feeding on a given day after dealing 400 damage in this way.

Rock Tunneler (Ex)

Using its acid to soften rock, a planetoid beetle can burrow through stone at half speed. It can make tunnels when it burrows.


Environment any vacuum
Organization solitary or pair

Asteroid lice and planetoid beetles feed on minerals in the rock of their airless habitats. Asteroid lice are communal, but planetoid beetles are territorial, tolerating only one mate. These creatures and their eggs can float in space to a new home. However, careless quarrying and shipping have accelerated their spread through the galaxy.

Xenobiologists theorize many space vermin evolved in special circumstances.
