Scolopendra subspinipes is a species of very large centipede found throughout southeastern Asia. One of the most widespread and common species in the genus Scolopendra , it is also found on virtually all land areas around and within the Indian Ocean, all of tropical and subtropical Asia from Russia to the islands of Malaysia and Indonesia, Australia, South and Central America, the Caribbean islands, and possibly parts of the southern United States, but how much of this range is natural and how much due to human introduction is unclear. [1] [2] With a wide geographic range and numerous color variations, the species is known by many common names, including jungle centipede, orange-legged centipede, Hawaiian centipede, and Vietnamese centipede.
It is among the largest centipedes with a maximum length of 20 cm (7.9 in). [3] This centipede is an active, aggressive predator that preys on any animal it can overpower. [4]
The species is normally considered to have a maximum length of 20 cm. [3] However, in 2018 a far larger specimen was recovered in Hawaii by Clayton Cambra, who captured what appeared to be a Scolopendra subspinipes that measured 36.6 cm in length. [5]
It has color variations: its body is usually red or reddish brown with yellow or yellow-orange legs. In common with other members of genus Scolopendra , it has 22 body segments, with each segment having one pair of legs. A pair of modified legs known as forcipules or toxicognaths can be found on its head, which is covered by a flat shield and bears a pair of antennae. The toxicognaths are the major tools used by the centipede to kill its prey or for defense, as they have sharp claws that connect to venom glands. [6]
Scolopendra subspinipes is an aggressive and nervous arthropod, ready to strike if interfered with and sensitive to vibrations nearby. [3] [4] It preys primarily on arachnids, including spiders, scorpions, and vinegaroons. It is large enough to overpower small vertebrates, such as mice or small reptiles, and will readily attempt to consume them. It tends to try to eat almost every living animal it encounters that is not longer than itself. [4] It seizes prey with its anterior legs and then uses its toxicognaths to inject venom. The prey is held by the centipede's other legs until it is subdued. When defending itself or attacking prey, the centipede uses its entire body, coiling around the animal and holding on with its legs, from which position it can use its toxicognaths to deliver venom. [7]
The male produces capsules containing mature sperm cells, spermatophores, which are deposited in a reservoir called the spermatheca of the female during mating. The female then fertilizes her immature eggs, oocytes, and deposits them in a dark, protected area. The female lays 50 to 80 eggs, which she vigilantly protects until they hatch and the baby centipedes molt once. If danger is detected, she wraps around her young to keep them safe. The young centipedes molt once each year, and take 3–4 years to attain full adult size. Adults molt once every year. They may live for 10 years or more. [7]
S. subspinipes venom normally causes extreme pain, among other symptoms. A fatal case was reported in the Philippines in which the centipede bit a 7-year-old girl on her head. She died 29 hours later. [4]
S. subspinipes is a popular pet among arthropod hobbyists. [4] The centipede was a traditional food source for Aboriginal Australians. [8]
The number of subspecies of S. subspinipes was historically unclear and varied between authors. Taxonomic characterizations incorporated plastic traits such as color and sulcus structure and the number and position of spines, producing indistinguishable and intergrading subspecies. A 2012 review found that some subspecies were in fact distinct species: S. subspinipes dehaani , S. subspinipes japonica , and S. subspinipes cingulatoides (renamed Scolopendra dawydoffi to avoid confusion with "Scolopendra cingulatoides", a junior synonym of Scolopendra cingulata ). [2]

Centipedes are predatory arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs.
Scutigera coleoptrata, also known as the house centipede, is a species of centipede that is typically yellowish-grey and has up to 15 pairs of long legs. Originating in the Mediterranean region, it has spread to other parts of the world, where it can live in human homes. It is an insectivore; it kills and eats other arthropods, such as insects and arachnids.
Scolopendra heros, commonly known as the Arizona desert centipede, giant desert centipede, giant Sonoran centipede, Texas black-tailed centipede, Texas redheaded centipede, and giant redheaded centipede, is a species of North American centipede found in the Southwestern United States and Northern Mexico.
Scolopendra gigantea, also known as the Peruvian giant yellow-leg centipede or Amazonian giant centipede, is a centipede in the genus Scolopendra. It is the largest centipede species in the world, with a length exceeding 30 centimetres (12 in). Specimens may have 21 or 23 segments. It is found in various places throughout South America and the extreme south Caribbean, where it preys on a wide variety of animals, including other sizable arthropods, amphibians, mammals and reptiles.
The Chinese red-headed centipede, also known as the Chinese red head, is a centipede from East Asia. It averages 20 cm (8 in) in length and lives in damp environments.
Lithobius forficatus, most commonly known as the garden centipede, brown centipede or stone centipede, is a common centipede of the family Lithobiidae.
Scolopendridae is a family of large centipedes.
Scolopendra is a species-rich genus of large tropical centipedes of the family Scolopendridae.
Scolopendromorpha is an order of centipedes also known as tropical centipedes or bark centipedes. This order includes about 700 species in five families. These centipedes are found nearly worldwide, with tropical and subtropical regions providing the richest diversity in species. This order includes the only known amphibious centipedes, Scolopendra cataracta, Scolopendra paradoxa, and Scolopendra alcyona.
Scolopendra polymorpha, the common desert centipede, tiger centipede, banded desert centipede, or Sonoran Desert centipede, is a centipede species found in western North America and the Hawaiian Islands.
Scolopendra morsitans, also known as the Tanzanian blue ringleg or red-headed centipede, is a species of centipede in the family Scolopendridae. S. morsitans is the type species for the genus Scolopendra.
Scolopendra viridicornis is a species of centipede in the family Scolopendridae which can be found within the Amazon rainforest, the type locality being in Brazil. Due to the geographic distribution of this species it is known as the Amazonian giant centipede.
Ssm6a, or μ-SLPTX-Ssm6a, is a toxin from the venom of the Chinese red-headed centipede. It has strong analgesic properties, probably owing to its strong inhibitory effects on Nav1.7 channels.
RhTx is a small peptide toxin from Scolopendra subspinipes mutilans, also called the Chinese red-headed centipede. RhTx binds to the outer pore region of the temperature regulated TRPV1 ion channel, preferably in activated state, causing a downwards shift in the activation threshold temperature, which leads to the immediate onset of heat pain.
Spooky toxin (SsTx) is a small peptide neurotoxin. It is found in the venom of Chinese red-headed centipedes, also known as golden head centipedes. It is originally composed of 76 amino acids, with a molecular weight of 6017.5 daltons, but loses the first 23 residues and becomes 53 residues long. SsTx is currently thought to be unique to Scolopendra subspinipes mutilans.
Scolopendra dehaani, the giant Vietnamese centipede, is a large scolopendrid centipede found across Mainland Southeast Asia. It is also found in India, Japan, Hong Kong, and the Andaman and Nicobar Islands.
Scolopendra japonica, formerly classified as Scolopendra subspinipes japonica, is a species of scolopendrid centipede mostly found in Japan, although specimens have been reported in other parts of Eastern Asia such as China, Taiwan, Myanmar, Cambodia, and Laos. They usually grow between 7.5 and 13 centimetres in length. It is known by the common names Japanese giant centipede and blue-head centipede.
