I’ve ever found. There’s a term, “meroplankton” which describes organisms who will spend only part of their lives, or earlier life stages drifting by with the plankton.

If you look at the

world map of distribution Helobdella leeches are everywhere - except the too cold near-polar places. They are also good invaders - as obviously has occurred here. But behind the hype an interesting find nevertheless.

The balloon worm looks nothing like a typical worm because it doesn’t live on the seafloor, it floats in the deep midwater. With a gelatinous, bag-like body for buoyancy, it drifts and feeds on sinking organic particles.

Usually, when something or someone touches a Christmas tree worm's feathery radioles, it would immediately retract back into its hole. But not blennies and gobies - the worms consider those fishes as homies who are allowed to touch their radioles.
