Is there any bug or animal that can live forever

No, everything dies eventually.

Nothing is entirely impossible to kill, but the appropriately named immortal jellyfish doesn't die of old age. After mating, it is reverted back to its juvenile form. However, it doesn't stay alive forever, as it does get eaten by predators and succumb to disease. It is theoretically possible for one to live forever, but there are always unnatural causes of death to worry about, so the chances of this happening are extremely low.

No, im sorry, nothing can live forever. But theres one thing that can live for as long as nothing eats it or kills it, or if nothing gives it a disease or if it doesn't get a disease.

Its this special type of Jellyfish. Im not sure exactly how, but when in danger or something, it releases these cells or something that make it (in a way) young again, like, it restores its body! I don't know exactly how, search it on the web!!! :D

There is the immortal jellyfish (Turritopsis nutricula).Once they reach maturity, they can revert to the polyp stage and restart their whole life.However, they can be killed by predators, disease..etc

No animal can live forever..All animals die eventually, and can be killed.

PS. Bugs are insects..Insects are animals..

One jellyfish is able to turn itself back into a sexually immature, juvenile form after it reaches sexual maturity. It may be immortal.

Therefore, if some rich man wants to be immortal, he may want to invest his money so he can find a way to turn himself into a jellyfish. LOL

No, even a perfect biological design is acted upon by external stresses that compromise its structure further and further. In other words, DNA is only a design for construction, not a repair manual.

I am a human animal and I haven't died yet. But I am sure I will. And I don't think any animal can live forever. Bugs? naw, they die too.

plants can live forever long as they get want they need

no
