Brood Leech Swarm

Solitary leeches abandon their usual stealth once they gather in seething, undulant masses, feeding on the living swiftly and mercilessly.

commonAmphibiousAnimalSwarm

Most smaller species of leeches don't tend to swarm, but brood leeches are prone to gathering in seething, undulant masses of squirming gluttony. When they collect in sufficient numbers to swarm, they eschew the stealth of a lone leech's feeding methods in favor of swift and merciless feeding.
