Are there more fish or birds?
Number of species: It’s estimated there are over 28,000 extant species of fishes, compared to approximately 10,000 extant bird species. We should also note that biomass is on our side too; it’s believed that the Bristlemouth fish is the most abundant vertebrate on the planet (hundreds of trillions)!
What animals have the most species?
In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
What percentage of species are birds?
The scientists weren’t surprised to find only a few super-abundant species, and many more rare ones, as is the common pattern in ecology. Overall, the scientists estimate that 1,180 bird species—12 percent of the world’s total—each have a total population below 5,000.
Which insect has the highest population?
ants
It hardly comes as a surprise that ants are the most numerous insect in the world. These colonial hymenopterans may number from 10-100,000 trillion individuals globally; there are more than 10,000 species.

How many species of birds and fishes are known?
About 5 to 30 million species of birds and fish exist on the earth.
How many species of birds and animals are there in the world?
The natural world contains about 8.7 million species, according to a new estimate described by scientists as the most accurate ever.
How many reptile species are there?
Currently there are more than 10,000 species and an additional 2,700 subspecies. This is making reptiles the largest vertebrate group after fish (~25,000 species) and birds (~10,000 species), and significantly larger than mammals (~5,000 species) or amphibians (~6,000 species).
