How many species have been identified?
Over 1.5 million species have been identified and described by scientists, but it is estimated that there could be anywhere from 5 million to over 100 million total species on Earth, with many still waiting to be discovered and classified. Each year, new species are being discovered in various ecosystems around the world.
How many indentified species of birds are there in South America?
There are many different species of birds globally, about 10,000 species. The greatest concentration in South America, where 1879 species have been identified.
Which specie have been on the earth for the shortest amount of time?
Some species that have been on Earth for a relatively short amount of time include domesticated species like dogs and cats, which have undergone significant evolutionary changes through selective breeding in a relatively short period compared to many wild species. Additionally, human-created species like lab-engineered organisms or genetically modified crops are examples of species that have been on Earth for a very short duration in their current form.
What portion of all species have scientists identified and named?
Of course, we have no idea exactly what proportion of all species have been classified, named, described or discovered.Currently there are at least 1 million named insect species, over 50 000 vertebrate species (of which 25 000 are fish, 5000 are mammals, 10 000 are birds, about 10 000 are reptiles and 6000 are amphibians) and 250 000 flowering plant species. What I have mentioned is only a tiny proportion of the number of species already named. The total number of named species probably approaches 2 million.In South America, insecticide fog was released into a tree's canopy, out of which fell thousands of specimens of insect. 80% of those specimens were of species not yet described.The number of tree species in the forests is better known than the number of insects (or arthropods in general). One argument took the number of tree species and multiplied it by the average number of insect species found to be specialist (to specific trees) per tree species. This yielded an estimate of undescribed arthropod species at 30 million. Since these seem to be the majority of life on Earth, it may be that the total of all life would in fact round off to this number of species; 30 million.Still there are estimates of the total number of species up to 100 million. I was conservative in my last thumbsuck-like guess of the total number of species on Earth and guessed 50 million or so. Yet everyone around me was aiming much higher, much closer to 100 million.2 million species described so far divided by 100 million in total and you can see the proportion of life so far discovered is astonishinly little. You may think we do know at least mostspecies. But then you imagine the undiscovered angler fish and crabs and polychaete worms in the endless depths of the unexplored oceans and the endless leafy heights of the rainforest trees crawling with insects................

Have all the organisms on the Earth been classified?
No, not all organisms on Earth have been classified. There are many undiscovered species, particularly in unexplored regions like the deep sea or remote rainforests. New species are continuously being identified and classified by scientists.

How long have flamingos been on earth?
According to the Smithsonian Institution's National Zoo, fossils of flamingos most similar to modern day forms have been identified to 30 million years ago. Fossils of more primitive species have been identified to be an estimated 50 million years old. See the link below for more information.
Are some alien races headless?
No alien species have yet been found or identified as such, therefore no definite answer can be given. If we want to speculate, in an infinite universe there will be a chance that headless species will occur, as headless species occur on Earth. They might even be intelligent!

There are 33 known species of seals out there that have been identified.
