Not to be confused with **GEOBIA**.

***Geobia*** is a [monotypic](/source/Monotypic_taxon) [genus](/source/Genus) of [land planarians](/source/Land_planarian) from South America.

## Description

The genus *Geobia* has a very elongated body. The only species in the genus, ***Geobia subterranea***, has several adaptations for a subterranean lifestyle, such as lack of eyes, pigments, and creeping sole, i.e., the ventral side has only some sparse cilia, unlike most other genera. The cutaneous musculature is very strong,[1] especially in the anterior region,[2] possibly as an adaptation due to its burrowing habits.

The [copulatory apparatus](/source/Reproductive_system_of_planarians) of *Geobia* has a permanent but small penis and an elongated prostatic vesicle. The female canal enters the genital antrum dorsally.[2]

## Distribution and ecology

*Geobia subterranea* is found in areas covered by the [Atlantic Rainforest](/source/Atlantic_Rainforest) in Brazil. Its known distribution includes the states of Rio de Janeiro, São Paulo and Santa Catarina.[3]

It is known to feed on earthworms,[2] attaching its body to the prey and sucking the contents after releasing digestive enzymes. The planarian's colorless body usually acquires a brownish or pinkish tinge after a meal due to the gut contents.
