[4] [2] It is one of the largest arthropods ever known, as large as the eurypterid Jaekelopterus rhenaniae, whose length is estimated at 2.33–2.59 metres (7 ft 8 in – 8 ft 6 in). [14] The 2024 study reported the complete head and trunk of a juvenile specimen of Arthropleura sp. (MNHN.F.SOT002123) from Kasimovian (~305 Ma) Montceau-les-Mines ...
S. heros var. castaneiceps found in Oklahoma, with red head and black body. S. heros is the largest centipede in North America. [2] It has an average length of 6.5 inches (170 mm), but can reach up to 8 in (200 mm) in the wild, [3] and even longer in captivity. [4] Its trunk bears either 21 or 23 pairs of legs. [5] [6]

“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
The genus Scolopendra contains many species of centipedes found across the world's tropics and warmer temperate areas. The species vary considerably in coloration and size. Scolopendra are mostly very large centipedes. The largest species found in tropical climates can exceed 30 cm (12 in) and are the largest living centipedes in the world. [2]
