Geophilidae

Common Name

Overview

The Geophilidae family encompasses a wide variety of centipedes known for their burrowing lifestyle. These segmented arthropods thrive in moist soil environments and are characterized by their elongated bodies and numerous legs, which they use to navigate through their subterranean habitats.

Taxonomy

Key Characteristics

  • Body Shape : Long, slender, often worm-like.
  • Segments : Typically 27 to 191 leg pairs, depending on the species.
  • Antennae : Long and multi-segmented, used for sensing their environment.
  • Eyes : Many species lack eyes, relying instead on antennae to navigate.
  • Color : Usually yellowish-brown to reddish-brown.

Life Cycle

  • Egg : Laid in soil; the mother often guards the eggs until hatching.
  • Juvenile : Smaller versions of adults; stages of growth depend on species.
  • Adult : Reaches maturity with full complement of leg pairs, continues to grow by molting.

Behavior and Ecology

  • Habitat : Prefers moist, dark environments such as soil, under logs, and leaf litter.
  • Diet : Predatory, feeding on other small soil organisms and detritus.
  • Reproduction : Internal fertilization; some species show parental care.
  • Activity : Generally nocturnal, emerging from the soil at night to hunt.

Notable Species

  • Geophilus flavus : Common European soil centipede.
  • Strigamia maritima : Found along European coasts; known for living in tidal zones.

Conservation

Most species within Geophilidae are not considered endangered. However, habitat destruction and changes in soil composition due to agriculture can impact local populations.

Significance to Humans

Soil centipedes play a crucial role in the ecosystem by controlling the population of soil-dwelling pest species and assisting in the breakdown of organic matter, thus enriching the soil.

Fun Facts

  • Geophilidae can have between 27 and 191 pairs of legs, making each species unique in leg count.
  • Many Geophilidae species are blind and rely heavily on their antennae to sense their environment.
  • Soil centipedes can burrow as deep as several feet in search of food or optimal moisture levels.
  • Unlike most centipedes, some Geophilidae display parental care by guarding their eggs.
