The Family Geophilidae is a group of invertebrates commonly known as soil centipedes. As their name suggests, they are often found in soil or underground environments. There are several synonyms for the Family Geophilidae, including Geophilomorpha, Geophilomorphs, Geophilomorphae, and soil centipedes. These synonyms are often used interchangeably, and all refer to the same group of insects. Soil centipedes are characterized by their elongated bodies, numerous legs, and ability to move quickly through soil and leaf litter. While they are not harmful to humans, they play an important role in soil ecology and decomposition.
