What is the number of species of fish?
about 32,000
The total number of living fish species—about 32,000— is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined.
What species has the most biomass?
The most successful animal species, in terms of biomass, may well be Antarctic krill, Euphausia superba, with a fresh biomass approaching 500 million tonnes. However, as a group, the small aquatic crustaceans called copepods may form the largest animal biomass on earth.
How many species of fish are there in the world 2022?

How many species of fish are in India?
In India, out of 877 native freshwater fish species, about 450 are Small Indigenous Fish Species (SIFS).
What is the most dominant species on Earth?
Plants rule the planet—at least in terms of sheer mass. Many tallies of Earth’s life use biodiversity as a measurement and simply count the number of species.
What’s the most successful species on Earth?
The Horseshoe Crab: World’s Most Successful Animal
- Horseshoe crabs are, arguably, the most successful animals on earth, having survived for 445 million years.
- It’s the ‘crab moon’ right now when hundreds of thousands of horseshoe crabs come ashore to lay eggs in the sands of Delaware Bay in the eastern United States.
What is fish biomass?
Fish biomass is derived from the total number of fish counted in a specific area of water multiplied by the average weight of fish sampled (Harvey et al. 2003), which can be used to predict daily intake demand to avoid under- or overfeeding (Alver et al. 2005).
What percentage of biomass is in the ocean?
Despite dominating our planet in terms of area and volume – taking up more than 70% of global surface area – the oceans are home to just 1% of biomass.
How many fish are there in the world 2021?
The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000.
What percent of species of fishes are found in India?
About 22000 species of fishes have been recorded in the world; of which, about 11% are found in Indian waters.
How many species of fish are there in India Class 9?
India has approximately 90,000 animal species. The country has about 2,000 species of birds. They constitute 13% of the world’s total. There are 2,546 species of fish, which account for nearly 12% of the world’s stock.
Which animal would rule the world?
The Ants There’s a good argument that ants rule the world already. Consider this: There are trillions of ants worldwide, far more than there are humans. Their total weight, if you could get them to sit on the scales long enough, would exceed ours. And they’re already ahead of most animals in the intelligence stakes.
Are humans the top species?
Based on that definition, the answer is no — humans aren’t top-predators because we don’t eat everything we kill. Related: What’s the first species humans drove to extinction? Bonhommeau and colleagues at IFREMER set out to determine humans’ position on the food chain, also known as their trophic level.
How do you calculate biomass of a fish?
What fish has highest biomass?
mesopelagic fish
With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean.
What percentage of species live in the ocean?
Scientists now estimate that 80 percent of Earth’s species live on land, 15 percent in the ocean, and the remaining 5 percent in freshwater.
