In general, the life expectancy of saltwater fish kept as a pet is around 20 years. Pet freshwater fish tend to live to about 15 years. Research done by the University of Michigan Museum of Zoology, pet goldfish have been recorded to live up to 25 years when kept in ideal conditions.
Which fish can live over 100 years?
Not only is the coelacanth one of the world’s oldest fish species, but the individual fish may also be long-lived. A new study suggests the ancient fish can live up to a hundred years and even longer.
What’s the longest fish live?
Instead a recent study from the University of Copenhagen discovered a Greenland shark they estimated (with 95.5% certainty) to be between the age of 272 and 512 years of age. Establishing a mid-point puts the shark’s estimated birth year at… 1627! This makes the Greenland shark the longest-living vertebrate on Earth.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.

What is the oldest thing on Earth?
SEA FOREST: Approximately 200,000 years. A sprawling sea grass meadow ten miles long near Spain ranks as the oldest known single organism on Earth, according to geneticists. Posidonia oceanica, known as Neptune’s grass, is endemic to the Mediterranean Sea.
Which is first language in world?
Dating back to at least 3500 BC, the oldest proof of written Sumerian was found in today’s Iraq, on an artifact known as the Kish Tablet. Thus, given this evidence, Sumerian can also be considered the first language in the world.
How was Earth created?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
How old is the water?
The water on our Earth today is the same water that’s been here for nearly 5 billion years. So far, we haven’t managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
Is Earth losing water?
Water flows endlessly between the ocean, atmosphere, and land. Earth’s water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
Will humans run out of water?
So it might appear that our planet may one day run out of water. Fortunately, that is not the case. Earth contains huge quantities of water in its oceans, lakes, rivers, the atmosphere, and believe it or not, in the rocks of the inner Earth.
Can we create water?
Yes, it is possible to make water. Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.
How old is the ocean water?
The ocean formed billions of years ago.
Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
How old is the first water?
Recent research suggests that water may have been first created less than 1 billion years after the big bang. This is thought to have taken place inside molecular gas clouds, which were nurseries for the second generation of stars.
How old is world’s water?
Which of these scenarios is responsible for the majority of water in the oceans is still unclear, but we know that most of the water in the oceans (and on the rest of the planet) is very ancient – on the order of 4 billion years old.
Is water older than the Earth?
Not only did some of our water at least apparently survive the infernal conditions of Earth’s early years and the moon-forming impact, it might be even older than our planet itself.
What came first water or ice?
Water as vapor. Oxygen is a product of nuclear fusion in a star. When the temperature of the gas was low enough for chemical binding, it made water steam with hydrogen. Only after condensation it liquified to water, cooling down it produced ice.
