Named for the Latin word for 'attack', the Luminous Oppugno is a crafty aquatic predator. Primarily nocturnal, it uses its bioluminescent-tipped rods to attract prey. Once within range, the main grasping appendage shoots out and arrests the unsuspecting victim with vigorous tenacity. Being fully aquatic (dwelling rather deeply at that) as well as nocturnal, the oppugno rarely comes into contact with sunlight, and thus has lost the capability of its ancestors to harness energy from photons. Thus, the creature must rely exclusively on its skill as a predator to meet its energy requirements. An adult oppugno usually tops out at around 5 feet long.
