Good luck, and watch out for tricks: some options look right at first glance.
A world of species
Scientists have already described about 1.5 million animal species, and most of them are insects. Estimates suggest that millions of species are still waiting to be discovered, especially in tropical forests and on the deep sea floor.
Brazil is among the countries with the most species in the world, with biomes as different as the Amazon, the Pantanal, the Cerrado, the Caatinga, the Atlantic Forest and the Pampa.
And many animals still hold mysteries. The place where European eels reproduce, in the Sargasso Sea, was only identified in the 20th century, and to this day no one has ever seen their spawning in the wild.
