Biodiversity and Cryptid Populations

Scientists are actively discovering new species, with estimates suggesting 3 to 5 million species exist, many of which are yet to be named. While most are insects, large animals like megafauna are still being found. In remote areas, new subspecies may be proposed. The concept of cryptids, like Sasquatch, is explored, suggesting a viable population could exist with numbers similar to endangered species like mountain gorillas, which have survived population bottlenecks.

What is the estimated range of total species on Earth according to scientists?

• 5 to 7 million

• 7 to 9 million

• 1 to 2 million

• 3 to 5 million
