Study Notes
Chilopoda Overview
- Class Chilopoda includes centipedes, recognized for their elongated and segmented bodies.
- Centipedes do not literally have 100 legs; leg count varies from 30 to 354, always having an odd number of pairs.
Anatomy and Physiology
- One pair of legs per body segment, with size increasing from front to back for efficient movement.
- Forcipules, unique to Chilopoda, are venomous limbs located at the mouth, aiding in prey capture.
- Breathing occurs through a tracheal system with spiracles located along the body.
- Sutures are the seams between body segments, contributing to their segmented structure.
Sensory and Defense Mechanisms
- Most have simple eyes (ocelli) for limited vision; some species possess compound eyes or none at all.
- Defense mechanisms include speed, venomous bites from forcipules, and the secretion of chemicals.
- Chilopoda possess specialized sensory organs known as Tomosvary organs.
Habitat and Behavior
- Found in diverse habitats, particularly in moist environments like leaf litter and under rocks.
- Nocturnal by nature, they are generalist predators that hunt a variety of soft-bodied prey, including slugs and snails.
- Chilopoda maintain a filamentous pair of antennae for environmental sensing.
Reproduction and Lifespan
- Females can lay between 10-50 eggs; some species exhibit matriphagy, where offspring consume their mothers.
- Lifespan ranges from 5 to 10 years, longer than many arthropods.
Ecological Role
- Serve as key predators in their ecosystem, controlling pest populations and providing a food source for various animals, including birds, mammals, and reptiles.
