How many species of animal are there in the Galapagos?

The Galapagos Islands are home to a diverse range of animal species, many of which are found nowhere else in the world. It is estimated that there are over 10,000 species native to the Galapagos, although exact numbers can be difficult to ascertain due to ongoing research and the presence of transient species.

The archipelago is particularly well known for its unique bird population, which includes iconic species such as the giant tortoise, marine iguanas, and various species of Darwin's finches. Here are some specific numbers for different animal groups found in the Galapagos:

- Reptiles: There are around 75 reptile species in the Galapagos, most notably giant tortoises (15 species) and marine iguanas.

- Birds: Over 160 bird species have been recorded, including 28 species of Darwin's finches, various boobies, frigate birds, albatrosses, and the famous waved albatross.

- Mammals: There are approximately 55 mammal species in the Galapagos, including native species like the Galapagos fur seal, sea lions, whales, and dolphins, as well as introduced species such as rats and mice.

- Fish: The waters surrounding the Galapagos host over 3,000 fish species, including tropical reef fish, sharks, rays, and numerous endemic species.

- Invertebrates: The Galapagos is home to a vast diversity of invertebrates, including insects, spiders, crustaceans, and mollusks. The estimated number of invertebrate species is in the thousands.

It's important to note that these numbers are subject to change as new species are discovered or revisions are made to taxonomic classifications. The exact count of animal species in the Galapagos is a complex and ever-evolving area of scientific study.
