Food coma: This enormous anaconda looks like it just enjoyed some lunch. The massive snakes, which can grow to 13 feet (4 meters) or longer, are the first new species of anaconda discovered since 1936. These mainly aquatic boas catch, suffocate, and eat a wide variety of prey. Big anacondas have been known to eat large caiman, and mammals as big as tapirs and even jaguars.

The new species of anaconda, discovered in 2002, is just one of a multitude of species scientists found in the Amazon from 1999 to 2009.
In a decade, researchers discovered 1,220 species in the region. That includes 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals.
Amazon Poison Frog
Over the course of ten years, 24 new species of poison dart frogs were discovered, the majority of them in the Peruvian Amazon. This vibrant species, Ranitomeya benedicta, officially described in 2008, is tiny, like all poison dart frogs. The dainty amphibians, which secrete a nasty poison from their skin to keep predators at bay, range in size between just over half an inch to just under 2.5 inches (1.5 cm to 6 cm).
Amazon Acari Marmoset
The Rio Acari marmoset (Mico acariensis), a small monkey, lives only in remote areas of the Brazilian Amazon. Discovered in 2000, the species has not been studied in the wild, and there is currently no reliable information on its population status or major threats.
Amazon Blind Catfish
In the dark, you don't need eyes: This strange, subterranean blind catfish is tiny, and it was only discovered in 2007 when the 1.3-inch (3.5-cm) critters turned up in buckets in hand-dug wells in Brazil.
Amazon Gonatodes Lizard
Twenty six lizards have been discovered in the Amazon in the last 10 years. This brightly-colored Gonatodes alexandermendesi is a male of the species.
