You see what looks like little Medusa heads coming out.

Most Medusa jellies make special structures called polyps, that simply bud off babies with no need for sex.

So this camera platform, which we called the Medusa, could just be thrown off the back of the ship, attached to a float at the surface with over 2,000 feet of line, it would just float around passively carried by the currents, and the only light visible to the animals in the deep would be the blue light of the optical lure, which we called the electronic jellyfish, or e jelly, because it was designed to imitate the bioluminescent display of the common deep sea jellyfish Atolla.
