The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years, a new study found. The slow- moving, people-sized fish of the deep are different from the live-fast, fast-living fish we’re used to seeing in the ocean today. “Living fossils are rare, but they’re not unheard of. But this is the first time scientists have found a living fossil of a fish that lives for more than a century.
And it’s not just any old fish, either. It’s the largest living fish known to science, with a body length of about 1.5 meters (5 feet) and a girth of up to 1 meter (3 feet), according to the study, which was published online today (May 16) in Science Advances.

Can fish live 20 years?
The majority of common tropical fish live for an average of three to five years, while goldfish are among those living the longest, potentially up to 20 years. The cousins of the goldfish are able to live up to 10 years in the wild.
Can a fish live for 12 years?
Neon tetras, angelfish, Oscars, and plecostomus are some fish that will be around for 10 years or more. The goldfish is the longest living freshwater fish. If provided proper feeding and a clean, healthy environment, these fish can live as long as 20 years.
The best way to determine the length of your fish’s life is to keep track of how much they eat and how often they are fed. This will give you an idea of the amount of time it will take for the fish to reach its maximum size.
Do human fish exist?
The olm, a foot-long salamander nicknamed “the human fish” because of its fleshy skin and tubular shape, is certainly a strange-looking animal. Olms can live for 100 years, which is far longer than any other amphibian. Scientists don’t know why they live so long, but they suspect it has something to do with the fact that their skin is made of the same molecule found in human fingernails and toenails.
Olms have been around for a long time. They were first described in the 18th century by the French naturalist Jean-Baptiste Léopold Trouvelot, who described them as “a kind of fish with a human face.” The name stuck, and the species has since been found all over the world, including the United States, Europe, Australia, South America, Africa, Asia and Australia.
Which animal can live up to 500 years?
The ocean quahog can live up to 500 years old. The quahog’s ability to protect itself from predator is believed to be the secret to its long life.
“It’s very hard to get a hold of one of these things because they’re so rare,” said Dr. David R. Smith, a marine biologist with the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service.
How do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some even locate their food by smelling the water.
In the wild, fish are usually found in groups of two or three, but in captivity they can be as large as 20 or 30 individuals. They are also often fed a high-fat diet, which can cause them to lose weight.
What is the oldest fish?
The world’s oldest living aquarium fish is believed to be located at the California Academy of Sciences. According to scientists, the oldest known animal is an australian lungfish named methuselah. Methuselsah was discovered by a team of researchers from the University of California, Santa Barbara, and the Australian National University in Canberra, Australia, in 2010.
The researchers named the fish after the biblical figure of the same name, who is believed to be the first man to walk on the moon. She was found in a limestone cave in Australia’s Great Dividing Range, which is home to a number of extinct species of fish, reptiles, amphibians, birds and mammals, according to the National Geographic Society.
What is the oldest fish alive?
The oldest fish in the world is the greenland shark, which has a female specimen that’s been around for more than 400 years. The longest-living animals on earth are the greenland sharks, who have a lifespan of at least 272 years.
How long can humans live?
Some people live to be over 100 and most of us can live to around 80. The oldest person in history was a French woman named Jeanne Calment. The average life expectancy in the U.S. is 78.5 years, according to the Centers for Disease Control and Prevention.
How old do goldfish live?
Some varieties live up to 30 years when provided with proper care, while others average about 10 years. Many goldfish don’t reach their lifespan potential because of poor housing conditions. They need housing to meet both their physical and behavioral needs. The best way to ensure that your fish is happy and healthy is to provide them with the best conditions possible.
If you are not sure how big your tank is, you can measure it with a tape measure. You can also use a ruler to measure the space between the bottom of your aquarium and the top of the fish tank. Once you have determined the size, it is time to decide on the type of tank you will be using.
Aquariums that are designed to house a variety of fish species. These tanks are often referred to as ‘fish only’ tanks.
How were fish created?
Fish may have evolved from an animal similar to a coral-like sea squirt (a tunicate), whose larvae resemble early fish in important ways. The path that the first ancestors of fish followed may not have been followed by all fish. The earliest known fish fossils are from the Early Cretaceous of China, and the fossil record of the earliest vertebrates is much more limited than that of reptiles and amphibians.
These include the first fish to be found in North American waters, a fish that lived on the shores of Lake Superior, as well as a fossil of an early tetrapod (an animal with four limbs and a backbone) that was found at the bottom of a lake in Canada.
