FINALLY found a few of these in an overgrown cave just now. The don't attach to the subs, instead they do the same hypnosis attack which forces you to drive the sub into them slowly, doing no damage to you or them.

The hypnosis is just your character getting pulled towards them, and the aggro range to have this occur appears short. Counteracting this is just trying to swim backwards.
