Determining the exact number of ocean animals is impossible; however, estimates based on current scientific research suggest a vast range.
According to available data, there are at least 243,613 known marine species. However, this figure is likely an underestimate. Scientific estimations suggest that the total number of marine species is:
- Likely at least 750,000 species: This figure represents a conservative estimate based on incomplete research, representing 50% of 1.5 million total species.
- Possibly as many as 25 million species: Some research indicates that the total number of marine species could be much higher. This would represent 50% of 50 million total species
The oceans, which cover 71% of Earth’s surface and contain 97% of its water, host this incredible diversity. The true number remains unknown due to ongoing exploration and the discovery of new species. The challenge of completely cataloging all marine life is immense because of the vastness and depth of the ocean.
Therefore, the best current estimate falls between *at least 243,613* known species and a potential maximum of *25 million* different marine species.
