Some jellyfish can glow in the dark.
Many jellyfish have bio-luminescent organs, which emit light. This light may help them in a number of different ways, like attracting prey or distracting predators.

Jellyfish can clone themselves.
If a jellyfish is cut in two, the pieces of the jellyfish can regenerate and create two new organisms. Similarly, if a jellyfish is injured, it may clone itself and potentially produce hundreds of offspring.

Some jellyfish are immortal. There are two phases to jelly life: the stationary polyp stage and the mobile medusa phase. It's the medusa phase that we're usually referring to when we talk about jellyfish. Typically, jellies start as polyps and develop into medusas, but the Turritopsis nutricula has earned it the nickname "the immortal jellyfish" for having the ability to travel backward to the polyp stage in times of stress.
Not all jellies have tentacles.
The scyphomedusa deepstaria, shown in the video below, doesn't need tentacles to trap its prey. |
Jellyfish don't have brains.
Instead, jellyfish have nerve nets which sense changes in the environment and coordinate the animal's responses

Glowing jellyfish goo could power medical devices.
Another jellyfish-derived product takes advantage of the jellies' fluorescent protein, and could be used to power medical devices in the future.
