Greenland sharks.
The oldest fish in the world is the Greenland shark, with a 392-year-old female specimen being the oldest ever discovered. With a lifespan of at least 272 years, Greenland sharks are now the longest-living vertebrates known on Earth, according to scientists.
What is the oldest species still alive today?
the horseshoe crab
Although it can be hard to tell exactly how old some species are and scientists are confident that they still haven’t uncovered nearly all the fossils that could be found, most scientists agree that the oldest living species still around today is the horseshoe crab.
What is the oldest species in the ocean?
Ocean quahogs are among the longest-living marine organisms in the world. The ocean quahog is a species of edible clam, a marine bivalve mollusk. Ocean quahogs live in the Atlantic and can live more than 400 years old. At 507 years of age, Ming the clam broke the Guinness World Record as the oldest animal in the world.
What is older than sharks?
Coelacanth – 410 MYA
The Coelacanth is one of the oldest known fish still alive today. There are two species, one living near Africa and the other near Indonesia. The oldest Coelacanth fossils are only 410 million years old, predating dinosaurs, trees, and sharks by a large margin.
What is the animal that 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.
What is the oldest predator on Earth?
Earth’s first big predatory monster was a giant underwater scorpion that reigned in the ocean almost half a billion years ago, well before the dinosaurs, scientists have discovered.
Which animal can live 1000 years?
Estimates of sponge longevity vary quite a bit, but are often in the thousands of years. One study in the journal Aging Research Reviews notes a deep-sea sponge from the species Monorhaphis chuni lived to be 11,000 years old. Yes, a sponge is an animal—and it has a remarkable life-span.
Are there fish we haven’t discovered?
So far, zoologists have reported on nearly all the mammal and bird species currently living on earth. There may be a dozen or so left that as yet are unknown to science. Most of the fish and reptiles are already identified, but there remain several thousand more left to find.
Did sharks exist before trees?
Sharks are older than trees and dinosaurs
The earliest evidence of shark fossils dates back as far as 450 million years, which means these creatures have been around at least 90 million years before trees and 190 million years before dinosaurs.
What existed before dinosaurs?
For approximately 120 million years—from the Carboniferous to the middle Triassic periods—terrestrial life was dominated by the pelycosaurs, archosaurs, and therapsids (the so-called “mammal-like reptiles”) that preceded the dinosaurs.
What animal is closest to dinosaurs?
In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs. So next time you visit a farm, take a moment to think about it. All those squawking chickens are actually the closest living relatives of the most incredible predator the world has ever known!
What animals have not evolved?
The goblin shark, duck-billed platypus, lungfish, tadpole shrimp, cockroach, coelacanths and the horseshoe crab — these creatures are famous in the world of biology, because they look as though they stopped evolving long ago. To use a term introduced by Charles Darwin in 1859, they are “living fossils”.
Which animal dies after drinking water?
kangaroo rat
However, if a kangaroo rat drinks water, the necessary bodily liquids and vitamins are flushed out, and it dies as a result of dehydration.
What animal never gets sick?
Sharks are the only animals that almost never get sick: they are immune to almost every known disease. Their body frames are not made up of bones – they are made of cartilage, the tough, fibrous tissue that shapes our noses and ears.
Do any animals not sleep?
Regardless of their preferred mode, bats, elephants, frogs, honeybees, humans and more have something in common: They all sleep. In fact, scientists have yet to find a truly sleepless creature.
What was the largest ocean predator ever?
megalodon
Predators and prey
In addition to being the world’s largest fish, megalodon may have been the largest marine predator that has ever lived. (Basilosaurids and pliosaurs may have been just as large.) Megalodon was an apex predator, or top carnivore, in the marine environments it inhabited (see also keystone species).
What is the largest land predator in the world?

List of largest land carnivorans

What animal has the most eyes?
Dragonflies (Anisoptera)
Some species of dragonfly have more than 28,000 lenses per compound eye, a greater number than any other living creature.
What is the oldest living thing on Earth 2022?
Individual plant specimens. Methuselah, a Great Basin bristlecone pine (Pinus longaeva) in the White Mountains of California, has been measured by ring count to be 4,854 years old. It is therefore the oldest known living individual non-clonal tree in the world.
Why is 95 of the ocean unexplored?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
Has anyone ever reached the bottom of the ocean?
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench.
