The Pantanal is the second largest biome flooded the planet earth, covering an area of 140,000
km2. The low slope of this vast basin of the Paraguay river hampers the flow of water and in
combination as the half-relief, leads to the emergence of environments characteristic associated
with the vegetation in mosaic with the old alluvial dikes, causing thus flooded environments,
semi - flooded and dried (Pasture and Paratudal), occurring in this way edaphic fauna adapted
to these conditions. The soil and litter this biome has a diverse fauna of mites, springtail, insects,
crustaceans and miriapods. Despite this wealth of organisms and edaphic semi-edaphics, little
is known yet on bioecology and its classification. Aiming edaphic know the wildlife of this region,
proposes to raise the analysis faunistic, diversity and abundance of these bodies, the four types
of environments. The survey was conducted in Step of Otter, city of Corumbá-MS. The soil of the
region is hydromorphic soil. The areas that remain flooded almost the entire year; soil halfflooded
(remains flooded during the flood of the river Miranda); dry soil (Grassland and Paratudal)
of pasture land consists of native grasses, Paratudal, coverage of grass native to mixed ipê
trees of yellow (Tabebuia sp). The collections were made in eight transects (of the four areas), in
each transect were collected four samples of soil, removed 10 meters between each point of
collection, totaling 32 points for sampling. The soil was collected with the help of the funnel
Berlese (modified) to eight centimeters in diameter, by five centimeters deep. Then the material
was placed in exhibitor table, equipped with five lamps of 25W, and remained in this table for
three days. Below each funnel was placed a plastic bottle of 10x5 cm, containing a portion of
liquid preservative to collect the bodies. The sorting and identification of bodies were made
with a stereomicroscope mark Carl Zeiss. The largest number and bodies were found in the
environment semi-flooded (216), with 118 mites, 80 springtail, 23 insects and crustaceans 3. In
the environment flooded were found (207), 66 mites, 80 springtail, 58 insects and 3 crustaceans.
In Pasture (79), 47 mites, 20 springtail, 12 insects. In Paratudal (136), 92 mites, 24 springtail
and 20 insects.
