Over half of all known species on earth are insects (from the Latin insectum, which means "cut into sections") The number of current species is estimated between six and ten million, and could represent over 85% of metazoan life forms on the planet. Insects are found in almost every environment, although few insect species live in the ocean.
Tricky question... Scientists have described and given scientific names to about 920,000 species of insects in the world, which is impressive since mammals (of which humans are one) only have approximately 4,000 known species. As for your actual question... It is estimated that there are 20-30 million species of insects on the earth at present. In a good year, taxonomists throughout the world describe and name about 2,000 species of insects.
Alot. It happends every day! How the heck don't you know that??!! Who ever you are your stupid! About 3.
I would say that mankind is. Have you ever known another species so capable of destruction?Since the question does not specify which species that you are inquiring about, one must fill in that information. If you are inquiring about which creature on Earth has the capacity to be the most unpredictable and dangerous in the greatest variety of circumstances, then Man is the correct answer.
The IUCN Red List has every KNOWN species on Earth.

The number of geckos in the world are not known, but it is safe to assume that there are millions.

there are thousands of known endangered species on earth however that are thousands of more unknown endangered species
Blue Whale, which is the largest animal to be known on Earth.
Every known spacecraft began on earth and went to other places. That's also true of every known drawing, component, fragment, subsystem, and model of spacecraft. Few of them ever returned to earth.
There are at least 35 species of pine trees known to be found in North America. This is roughly a third of all species on Earth.
Porpoises are not actually dolphins, they are both different branches of sea mammals known as ceteceans but they are not the same so in answer to your question porpoises were not the first dolphin species on earth because they are not a dolphin.
1.7 - 2.0 million are currently known. more have yet to be discovered
