Pauropods are soft, cylindrical animals with bodies 0. They have neither eyes nor hearts, although they do have sensory organs which can detect light. There are long sensory hairs located throughout the body segments. Pauropods can usually be identified because of their distinctive anal plate, which is unique to pauropods.
Different species of pauropods can be identified based on the size and shape of their anal plate. The antennae are branching, biramous , and segmented, which is distinctive for the group. Their head capsules show great similarities to millipedes: both have three pairs of mouthparts and the genital openings occur in the anterior part of the body.
Moreover, both groups have a pupoid phase at the end of the embryonic development. The two groups probably have a common origin. There are two orders: Hexamerocerata and Tetramerocerata ; Hexamerocerata has a purely tropical range, while in Tetramerocerata most genera are subcosmopolitan. The representatives are white and proportionately long and large.
The one family in this order, Millotauropodidae, has one genus and a few species. Representatives of this order are often small sometimes very small , and white or brownish. Most species have nine pairs of legs as adults. Most genera and species belong to the family Pauropodidae. Behavior, reproduction, and diet[ edit ] Pauropods are shy of light, and will attempt to distance themselves from light sources.
Male pauropods place small packets of sperm on the ground, which the females use to impregnate themselves with. Pauropods have been known to eat mold , fungal hyphae , and the root hairs of plants.
