Millipede

Millipede (/ˈmɪlɪˌpiːd/; from Latin mille, "thousand", and pes, "foot") is a group of arthropods that are characterised by having two pairs of jointed legs on most body segments. They are known for their elongated, segmented bodies and numerous legs.

Etymology

The term "millipede" is derived from the Latin words mille meaning "thousand" and pes meaning "foot". Despite the name, no known species has 1,000 legs, the record holder, Illacme plenipes, has up to 750.

Anatomy

Millipedes are arthropods in the class Diplopoda. They have a segmented body with each segment bearing two pairs of legs. Their head is rounded with short antennae and they have a hard exoskeleton.

Behavior

Millipedes are typically slow-moving detritivores, eating decaying leaves and other dead plant matter. Some species can produce a toxic liquid secretion or hydrogen cyanide gas through microscopic glands along the sides of their bodies as a means of defense.
