Trilobite Swarm

Trilobites typically live in close proximity to others of their kind. On rare occasions, particularly when the most common prey around is larger than what a single trilobite can take down, they form swarms that seem to actively cooperate with each other. These swarms latch onto their prey, and the combined efforts of so many trilobites at once make escape difficult.

Often overlooked as little more than water-dwelling pests, trilobites are a varied species of arthropods found throughout the seas and oceans of Golarion. So ancient and widespread are these critters that trilobite fossils are as commonly found as living specimens.

Sidebar - Related Creatures Tremendous Variety

Scholars of the sea have identified thousands of varieties of trilobites, each distinguished by appearance, habitat, size, and diet. The smallest trilobites are an inch or two long, while individuals measuring almost two feet long have been found in the depths of the ocean. Some hide in silt, using tall eyestalks to spot prey, while others have wide, sweeping, wing-like heads; certain kinds are even covered in spines. This variety in appearance has led to distinctive jewelry in seaside villages that imitates local trilobite populations.
