It turns out they're called Craspedacusta sowerby, a fresh-water bell-shaped jellyfish. They're very delicate and have many tentacles when fully grown. Most of the body is transparent or translucent, with a whitish or greenish tinge.

Wikipedia reports prey is caught with their stinging tentacles. The jelly waits for suitable prey to touch a tentacle and when it does it injects poison which paralyzes the animal, and the tentacle itself coils around the prey. However, these cnidocytes cells are used for paralyzing very tiny prey and have not been proven to have the capacity to pierce human skin.
