Can a jellyfish regenerate body part?

Here's how it works:

* Not all species: While many jellyfish can regenerate, the ability varies between species.

* Limited regeneration: They can regenerate parts like tentacles, but they don't typically regenerate their entire bodies.

* Cell division: Regeneration occurs through a process called cell division. The jellyfish's cells are able to divide and differentiate to create new tissues and organs.

Examples:

* Moon jellyfish: These jellyfish can regenerate their tentacles and bells if they are damaged.

* Box jellyfish: Some species of box jellyfish can regenerate their tentacles and even their stingers if they are lost.

Interesting facts:

* Immortal jellyfish: There's a species called *Turritopsis dohrnii* that has the unique ability to revert to its polyp stage after reaching maturity. This means it can technically live forever!

Important note: While jellyfish can regenerate, it's important to remember they are delicate creatures. They should be treated with respect and care in their natural environment.
