The Domains of the Animal Kingdom
Arthropods the largest and most diverse group in the animal kingdom, they represent approximately 80% of the known species on Earth. This phylum includes insects, arachnids, crustaceans and myriapods, occupying practically all habitats on the planet and playing crucial roles in ecosystems.
Features
Arthropods are recognized by their rigid exoskeleton, made of chitin, which offers protection and support, but needs to be shed periodically through molting. Another feature is the segmented body and articulated legs, which guarantee great mobility and adaptation to different environments.
Diversity of Groups
Insects: Such as bees, butterflies and ants, they represent the largest group, with more than 1 million described species. Many are essential in plant pollination and pest control.
Arachnids: These include spiders, scorpions and ticks. They stand out for being predators and for their importance in controlling populations of other insects.
Crustaceans: Such as crabs, shrimp and lobsters are essential to the marine food chain and commercial fisheries.
Myriapods: Represented by centipedes and millipedes, they contribute to the decomposition of organic matter in the soil.
