Definition Water parcels in which gametes and larvae from various worm taxa are aggregated (often in very high abundance) after simultaneous spawning, and they are the dominant form of zooplankton. Epitokes may also be present. Epitokes are the detachable swimming gonad sections that form the posterior end of many species of polychaetes in their pre-breeding stage; these epitokes are released during spawning events, and appear as free-swimming worms.
