Are jellyfish good for anything?
For scientists, however, jellyfish are fascinating research subjects – they play important roles in the marine ecosystem and are a key source of food for some fish and sea turtles. Some even protect commercially valuable species, such as oysters, from predators.
Can sharks eat jellyfish?
Some sharks will eat almost anything. The Tiger shark, for example, is a species of shark that’ll chow down on a jellyfish. But whale sharks have also been known to swallow the small ones whole.
How long do jellyfish live for?
One of the most popular jellyfish, the moon jellyfish (Aurelia aurita), is known to have a lifespan of 12 to 18 months but with proper living conditions, can live up to 20 years. The Flame jellyfish (Rhopilema esculentum) has a rather shorter lifespan as it can only live from three months up to a maximum of one year.
Can jellyfish survive being cut in half?

Imagine if you could just split yourself in half and create two of you? If you cut a jellyfish in half, the pieces of the jellyfish can regenerate and turn into two new jellies.
Does a jellyfish feel pain?

Can jellyfish still sting when dead?
The tentacles of the jellyfish have tiny stingers called nematocysts which can detach, stick to skin, and release venom. Even if the jellyfish is dead, it can still sting you because the cell structure of nematocysts is maintained long after death.

Do killer whales eat jellyfish?
Transient killer whales sometimes play with their food, but they’ve rarely been documented toting jellyfish, or sea jellies, in their mouths.
Do jellyfish make turtles high?
