Pneumodesmus newmani is the earliest member of the millipedes from the late Wenlock epoch of the late Silurian around 17] [18] or early Lochkovian of the early Devonian around 414 million years ago, [19] [20] known from 1 cm (1 ⁄ 2 in) long fragment and has clear evidence of spiracles (breathing holes) attesting to its air-breathing habits.
The desert millipede is small, long, has many legs and body segments. The head, which is the first body segment, has a paired organ called the Organ of Tömösváry. This is a sensory organ located at the base of each of the antennae. For every body segment there are two pairs of legs. Desert millipedes shed every time they add a new body ...
One-year-old immatures (stages 7–9) are light brown with a darker medial stripe. After 2 years the 10-11 stage millipedes have turned black. Adult Portuguese millipedes are smooth, 20–45 millimetres (0.8–1.8 in) long and coloured from grey to black. Millipedes older than 1 year moult only in spring and summer.
One notable example was Arthropleura, the biggest bug ever known at up to 10-1/2 feet (3.2 meters) long, inhabiting what is now North America and Europe. ... Having two pairs of legs by segments ...

Archispirostreptus gigas, known as the giant African millipede, shongololo or Bongololo, is the largest extant species of millipede, growing up to 33.5 centimetres (13.2 in) in length, 67 millimetres (2.6 in) in circumference.
Under a microscope, the millipede with its 486 legs and helmet-like head resembles a creature in a Hollywood monster film. The City of Angels, a metropolis of freeways and traffic, has a newly ...
Millipedes in the order Siphonophorida are long and worm-like, reaching up to 36 millimetres (1.4 in) in length and up to 190 body segments. Eyes are absent, and in many species the head is elongated into a long beak, with mandibles highly reduced. The beak may serve in a suctorial function. The body has a dense covering of fine setae.
