1. Family Hydrobiidae-October 22, 2009 - This newly discovered in the basement of the family Hydrobiidae snails live in the aquifers in the heart of Australia, about 100 miles (180 kilometers) northwest of Alice Springs.
0.5-inch-long (1.3-centimeter-long) snail is one of 850 new invertebrate - simple animals that includes small crustaceans, spiders, and worms - in a four-year survey of the dry Australian outback.
Eel cave-2.blind this newfound eels do not need eyes in subterranean habitats, a trait shared by most of the creatures new underground recently discovered in Australia.
at 16 inches (40 centimeters) long, eel rare - found in aquifers along the Cape Range mountains. is the longest subterranean species known in Australia, researchers said.
3. Unnamed-Uniquely adapted to live on the surface of the spring, this new, unnamed Austrochiltonia crustaceans in the genus are found only in the Great Artesian Basin of South Australia.
Little creatures at risk of extinction should be with the original springs disturbed by mining or agriculture, say scientists who recently conducted a survey in Australia four years underground habitats.
In total, more than 850 new species were identified during the survey was found near the town, said the researchers.
"What we have discovered is that you do not have to go find the depth of the ocean to discover new species of invertebrate animals - you only need to look in your own backyard," team member Andy Austin, the University of Adelaide, said in a statement.
Hold a 4.unnamed-woodlouse leg, the kind that this unnamed blind pseudoscorpion found living in the air spaces above the ground in aquifers.
0.1-inch long (3-millimeter-long) animal is one of many scorpion-like arachnids found during scientific research recently, which identified only a fifth of the unknown species believed to exist in Australia in the basement, scientists said.
5. unnamed-This newly discovered, 0.1-inch-long (3-millimeter-long) adolescents in the genus plant hopper feed Hemipteran on sap from plant roots underground.
Over the last four years in Australia survey of underground critters, researchers had 105-degree-Fahrenheit (40 degrees Celsius) heat, monitor lizards and snakes brown cozying up to the location of research, and hydrogen sulfide gas from a vent, team members Steve Cooper, from the Australian Museum South, said in October 2009.
Cave fish 6.blind veritas Milyeringa new-found, seen above, Cape Range aquifers occupy the same as the blind cave eel found during the same survey in the Australian underground habitats.
The only blind cave fish known in Australia, 2-inch-long (5.1-centimeter-long) species are "very flexible," living in fresh water or sea water in coastal areas in the basement during the various stages of life, researchers say .
7. blind spider-Many of the 850 new species found during surveys in the Australian underground habitats, such as spiders are blind, was "really something unexpected in unexpected places," team member Steve Cooper, from the Australian Museum South, said in October 2009.
For example, a scientist found an arachnid in western Australia dry pastureland that has been considered only in the rainforest - the first time in a group of species ever found in Australia, said Cooper.
8.The Crustacea Phreatomerus latipes, previously considered a single species, is divided into eight distinct species that evolved in geographically isolated springs in South Australia.
Up to 0.8 inches (2 cm) long, the creature - found nowhere else on Earth - depends entirely on underground water released from underground springs for survival.
Many of the 850 species found in Australia for four years developed in isolation underground surveys and small caves. Animals may take shelter under the ground after the central and southern Australia dry about 15 million years ago, the team said.
New discoveries provide a "window of amazing" in past climate change and how animals evolved from surface to underground animal species, team members Steve Cooper, from the South Australian Museum, said in October 2009.
Paroster mesosturtensis, and Paroster microsturtensis-Three species of blind, wingless water beetles in the family Dytiscidae (picture, from left to right, Paroster macrosturtensis, Paroster mesosturtensis, and Paroster microsturtensis) recently found living in soil in the western part of Australia's dry pastureland.
Larvae (not pictured) is a "fierce looking predator" who may eat smaller crustaceans - and even each other, the scientists said in October 2009.
