There is a debate among the scientific community whether these red ocean dwellers are biologically immortal animals; a common cause of death is disease, not old age, and unlike other animals, lobsters grow and reproduce until they die. One lobster captured off the coast of Newfoundland was estimated to be 140 years old, but most males survive into their early 30s while females live an average of 54 years, according to Smithsonian. Fun fact: The bigger the lobster, the older it is.
Slow and steady really does win the race. Turtles have been known to live for centuries, and researches have found that their organs don’t seem to break down over time. The New York Times reports that turtles might even be able to live indefinitely if they are able to avoid predators and disease. In other words, they definitely have a potential to be immortal animals. Don’t miss the 8 smartest animals that learn faster than humans.

These creepy crawlers, also known as planarian worms, are famous for their regeneration abilities, where a worm cut across or lengthwise can form two separate worms. This apparently limitless regeneration also applies to aging and damaged tissue, allowing the worms to cheat death indefinitely, according to a study at the University of Nottingham.
