Take a closer look at the fascinating world of *centipedes**! This **nature education* clip shows you why these *insects* are more interesting than frightening. Learn some amazing *animal facts* about the *myriapoda* family.
Centipedes are a diverse and fascinating group of animals with a wide range of adaptations. If you want to dive deeper into the world of centipedes, here's more information on their different types, their diet, life cycle, and the nature of their venom.
All centipedes are predators. Their hunting strategies vary depending on their size and species.
Primary Prey: Smaller centipedes primarily feed on insects and other small invertebrates like spiders, ants, termites, and cockroaches. This is why house centipedes are often considered beneficial.
Larger Prey: Larger species, such as the giant scolopendrids, are capable of taking down much bigger prey. They have been documented hunting frogs, lizards, rodents, and even bats. In one remarkable case, a species of giant centipede in Venezuela was found to hang from cave ceilings, ambushing bats in mid-flight.
Hunting Techniques: Centipedes use their venomous forcipules to inject venom and paralyze their prey. They are active hunters, using their speed and sensitive antennae to locate and capture their meals. Some species also show cannibalistic tendencies, especially the larger ones, which may prey on smaller or injured centipedes.
Life Cycle and Reproduction
Centipedes have a relatively simple life cycle without a major metamorphosis, and they are surprisingly long-lived for arthropods.
Mating: Centipedes do not copulate. Instead, the male deposits a spermatophore (a sperm packet) for the female to pick up. In some species, this is preceded by a courtship dance.
Eggs: Females lay eggs in a protected, moist location, such as in soil or rotting wood. Some species, particularly scolopendrids and geophilomorphs, exhibit remarkable parental care. The mother will curl around her eggs to protect them from predators and clean them to prevent fungal growth.
Growth: Centipede young often hatch with a fewer number of legs than adults, gaining more with each molt. They can take several years to reach maturity, and some species have been known to live for a decade or more.
Centipede Bites and Venom
While the thought of a centipede bite can be alarming, it's important to understand the actual risk to humans.
How they bite: Centipedes don't bite in the traditional sense. They use their venomous forcipules to "pinch" or puncture the skin and inject their venom.
Venom Composition: Centipede venom is a complex mixture of various toxins, including neurotoxins, cardio-depressants, and histamine, which can cause severe pain.
Symptoms: For most small centipedes, the bite is comparable to a bee sting, causing localized pain, swelling, and redness.
Risk to Humans: While centipede bites are painful, they are generally not life-threatening to humans. The pain can be intense and last for several days. However, in rare cases, especially with bites from larger species, or in individuals with allergies, more severe reactions can occur, including nausea, chills, fever, and in extremely rare cases, anaphylaxis. There have been a few documented deaths attributed to centipede bites, but these are exceptionally rare and often linked to secondary complications or pre-existing conditions.
