Globular Drop Snails are one of the most ubiquitous terrestrial snails in Texas. They are primarily found in wooded areas near freshwater creeks, lakes, reservoirs, and river basins. They are also prominent in prairie habitats and mesquite forests. Globular Drops have one pair of tentacles, but no eye stalks. Their eyes are located on the main body just behind the tentacle base. The body is a translucent gray color.
Olygyra shells very little in size. However, they vary greatly in color, ranging from red to orange, yellow, purple-gray, and mossy green. They also display a wide range of patterns, including dark specks, mottled spots, and sometimes a single broad stripe like a billiard ball. Most specimens, however, are solid white. The Globular Drop is one of the few terrestrial mollusks to sport an operculum. This allows them to survive arid conditions and dry spells.
Globular Drops have a snout-like proboscis and a pair of highly active, chemoreceptive tentacles.
Globular Drops are one of only a few terrestrial snails that have an operculum, or trapdoor. This helps them survive long periods without water.
