Do sharks grow indefinitely?
Sharks keep growing until they die. Based on Deep Blue’s size, scientists estimate her age is around 50 years old. A large sharks means that humans haven’t killed it, and that they can breed longer. Sharks aren’t the only animal that keeps growing.
Why do sharks never stop growing?
Some sharks appear to keep growing throughout their lives, exhibiting indeterminate growth. This is thought to be beneficial to heat retention and predator avoidance, though recent evidence is calling into question whether sharks do continue growing their entire lives.
What animal can grow infinitely?
The actual size of most mammals – including humans – is mostly set from birth. Our growth rate is influenced by the environment, but our skeleton stops growing once we reach adulthood. But it’s true about kangaroos — they indeed never stop growing.
Is there an animal that never stops growing?
However, many animals, including some mammals, keep growing throughout their lives. Kangaroos, for example, just keep growing and growing until they die. Most fish, amphibians, lizards, and snakes are also indeterminate growers.
What never stops growing?

Eyes (cornea) never grow from birth till death because of absence of blood supply.
What animal never dies?
jellyfish Turritopsis dohrnii
To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Are Eels immortal?
Eels can live for a very long time, up to 85 years that we know for sure. But usually when they are 15 to 30 years old, they suddenly leave the freshwater and swim out in the ocean again and return to the Sargasso Sea.
