Diplopoda

Diplopoda is a class of arthropods, known more commonly as millipedes. They are characterized by their elongated bodies and numerous leg pairs. Millipedes are found in a variety of environments worldwide and play a crucial role in the decomposition of organic matter.

Characteristics

Millipedes are easily recognized by their elongated, cylindrical or flattened bodies, and the presence of two pairs of legs on most of their body segments. They range in size from 2 mm to around 35 cm in length. The color of millipedes can vary from brown to black and some species may have orange or red markings.

Habitat and Distribution

Millipedes are found in almost all parts of the world, from back gardens to Rainforests, on all continents except Antarctica. They prefer moist environments and are most active at night.

Behavior and Ecology

Millipedes are detritivores, feeding primarily on decaying organic matter. Some species are also known to eat live plants, especially seedlings. Millipedes are preyed upon by a variety of animals such as birds, mammals, and larger insects.

Reproduction

Millipedes undergo a process called anamorphosis during their development. After a certain number of molts, they gain additional body segments and pairs of legs. Millipedes lay their eggs in the soil, and most species reach sexual maturity in their second year, living several years after that.

Human Interaction

While millipedes are not typically dangerous to humans, some species can produce irritating secretions which can cause allergic reactions in some individuals. They are considered beneficial to the environment due to their role in breaking down organic matter.

Taxonomy

The class Diplopoda is divided into sixteen orders, with approximately 12,000 species described. The taxonomy of millipedes is still not fully understood, with many species yet to be described.
