The Peruvian giant centipede (Scolopendra gigantea), also known as the Amazonian giant centipede, is one of the largest centipedes in the world, reaching lengths of approximately twelve inches (30 centimeters) (Dunlap, 2025). Despite its common name, the species is best documented in northern South America, particularly Venezuela and nearby regions. Its exact distribution within the Amazon Basin remains uncertain. Like other centipedes, it belongs to the class Chilopoda and is more closely related to millipedes than to insects.

The Peruvian giant centipede has a long, flattened body divided into numerous segments, each bearing a pair of legs. Its coloration varies from reddish brown to darker shades, helping it blend into its surroundings. Although centipedes have many legs, they are not insects, which have only six. The first pair of appendages behind the head is modified into venom-injecting structures called forcipules. These are used to immobilize prey and provide protection against predators.

These centipedes are generalist predators that feed on a wide variety of animals. Their diet includes insects, spiders, and other invertebrates, as well as small vertebrates such as frogs, lizards, rodents, and bats. They are primarily nocturnal hunters, using their antennae to detect prey and navigate their surroundings. Once prey is captured, the centipede injects venom through its forcipules and holds the struggling animal with its powerful legs.

One of the most remarkable behaviors documented in this species is its ability to hunt bats. In Venezuelan caves, giant centipedes have been observed climbing onto cave ceilings and hanging partially upside down, anchoring themselves with their rear legs. From this position, they extend the front portions of their bodies into the air, allowing them to seize bats flying nearby. After capturing a bat, the centipede injects venom and begins feeding, sometimes remaining suspended while consuming its prey (White, 2022). This behavior demonstrates that these predators are capable of capturing animals much larger than the invertebrates typically associated with centipede diets.

The venom of Scolopendra gigantea is powerful enough to subdue relatively large vertebrate prey. In humans, bites can produce intense pain, swelling, redness, and other symptoms. Serious complications are uncommon but possible, particularly in vulnerable individuals. A fatal bite involving a young child has been reported in association with this species, although the identification and circumstances of the case warrant careful verification. Despite their fearsome reputation, these centipedes do not ordinarily pursue humans and generally bite when threatened or handled.

As predators, giant centipedes help regulate populations of smaller animals in the ecosystems they inhabit. They are also potential prey for larger vertebrates, making them part of a complex food web. Their unusual combination of size, venom, agility, and hunting behavior makes them among the most formidable terrestrial arthropod predators in tropical South America.
