Millipede | Facts, Diet, Habitat & Pictures

Millipede Overview

Appearance

Millipedes are elongated arthropods with cylindrical bodies segmented into numerous segments. They typically range from a few centimeters to several inches in length, depending on the species. Millipede is characterized by having two pairs of legs on each body segment, with the number of segments varying by species but often exceeding 30.

They come in various colors, including brown, black, and reddish-brown, and often have a protective exoskeleton. Millipedes are slow-moving and have antennae on their heads.

Origins And Evolution

Millipedes belong to the class Diplopoda and have ancient origins dating back to the Silurian period, over 400 million years ago. Fossil records reveal their evolutionary history as one of Earth’s oldest land-dwelling arthropods. Early millipede ancestors likely emerged from aquatic environments, gradually adapting to terrestrial life.

Over millions of years, they diversified into a wide array of species, each with specialized adaptations for different habitats. Millipedes have retained their characteristic segmented body plan throughout their evolutionary journey.

Their evolutionary success is attributed to their ability to recycle decaying plant matter and their chemical defenses against predators, including the secretion of toxic compounds. Modern millipedes continue to thrive in various ecosystems worldwide.

Behavior and Lifestyle

Millipedes are primarily nocturnal creatures, preferring to be active during the night to avoid predators and conserve moisture. They are detritivores, playing a crucial role in ecosystems by consuming decomposing plant material and returning nutrients to the soil.

Millipedes are slow-moving, relying on their many legs for locomotion, and are often found in damp or moist environments, such as leaf litter and rotting logs. They have a shy and non-aggressive nature, mainly using chemical defenses to deter predators, secreting substances that can be irritants or toxins. Millipedes often curl into a spiral when threatened, protecting their vulnerable underside.

Millipede FAQs

Are millipedes dangerous to humans?

No, millipedes are not dangerous to humans. While they can secrete substances that may irritate the skin or eyes, they are generally harmless.

What do millipedes eat?

Millipedes are detritivores, primarily feeding on decomposing plant material, dead leaves, and organic matter found on the forest floor.

Why are millipedes often found in damp places?

Millipedes require moisture to survive, so they are commonly found in damp or moist environments to prevent desiccation (drying out).

Are millipedes and centipedes the same thing?

No, millipedes and centipedes are different.
