About 30,000 flowering plant species are known from the Amazon Basin, the
world’s richest region and nearly three times the number claimed by all of Europe.
There is no realistic idea of how many insect species there might be in the Amazonian rainforest, though it is probably
in the millions. All of these, in one way or another, are ecologically linked
to flowering plants.

18,000 years ago sea levels were nearly 426 feet lower than today. During low sea level periods Amazonian rivers ran faster and sliced into the soft sediments to a depth
of more then 330 feet in several places below Manaus. Today, the average depth
of the Amazon River during floods is 98-164 feet.
