"Many species of polychaetes undergo epitoky whereby sexually immature worms transform into pelagic morphs capable of sexual reproduction. After fertilization, they release their gametes through rapid disintegration."
worms are out here having insane sex we can't even comprehend
"what do they mean by disintegrate?"
"oh yeah no he fucking disintegrated"
This skips the best part! The epitoke isn't the "real" or "original" worm. The worm grows an extra body with a simpler brain that only knows how to swim and cum (by exploding) so this part breaks off and the rest of the worm just stays home.
In some species the epitoke, or what I think should be renamed the cummunculus, is advanced enough to have its own eyes and everything, though only so it at least knows the right direction to swim (up) because it's so stupid and all
