Hysteria

The Hysterias are microscopic predators living in big swarms. They look like tadpoles with big teeth.

Biology
Living in the waters of the big Stingerfan-forests of Aurelia they communicate chemically and act perfectly together. A Hysteria-Swarm is able to kill and eat everything, from a Mudpod to a Stingerfan, even a Gulphog, because the swarm acts like one organism. They kill their prey by injecting them with neurotoxins and consuming the corpse.
