Wild beasts of the imagination — untamed spirits of the quick and unfettered waters of this world. These steeds of the fast-flowing rivers are never to be captured, never to be controlled; to stop is to die — to be stopped is to be turned to droplets which return to the fast-flowing waters. Yet, while free they are things of pure beauty; mystical bringers of the gods' good will.

I try to avoid them if I can. I see them sometimes herding their flocks of flabby grey creatures into and out of Boston harbor, and it always gives me the chills. Briano tells me that they brought me back to life, but I can't remember it. I can't remember a lot of stuff. He also tells me that I was good friends with one of them once. One of the ones that begs outside of Grand Island Bank for nickels or blood. I can't tell you why I'm uncomfortable around them. They're just fish.

Vastids - man-maimers who live in contaminated water areas and Balrin Algae.
Toltep walked slowly along the avenue, it would have been easier to swim along in the viaduct, but he had made it a point to not do the easy thing. All to often the easy path lead to ruin, and he had not survived so long by taking shortcuts, or the easy road. The market, what was above water, was abuzz with conversation.

Classified as a category 4 threat, the Elib is somewhere between a vampire lord and Godzilla for limits of escalation. Yes, I would consider using a nuclear device to kill just one. I am that sure that I want it dead.
Arakis's zombie problem went largely ignored, because it was believed that the Shai-Hulud (sand worms) would effectively dispose of the undead walkers. Unfortunately the problem grew until the roving herds of sunburnt ghouls threatened the flow of spice.
