But surprisingly, we still donât know how many species live by the shore: estimates vary widely, from 178,000 species to more than 10 million.

Over seven million species of plants and animals live on planet earth, according to the best estimates made by biologists. If you add in the world's species that aren't plants or animals, such as lichens, mushrooms and bacteria, the total number of species leaps much higher. Tallying the estimates of all living things brings the number to 11.3 million species currently on earth.
