Group overview
This is a smaller arthropod order with specialized ecological roles. Arthropods are the most diverse animal phylum, comprising over 80% of all known animal species with approximately 1.2 million described species globally.
Ecological role of the group
Members of this order contribute to broader arthropod ecosystem functions including decomposition, predation, and serving as food sources for vertebrates. Arthropod biodiversity is essential for ecosystem resilience.
Economic and practical significance of the group
While this order has limited direct economic impact, arthropods collectively provide ecosystem services worth trillions of dollars annually through pollination, decomposition, pest control, and nutrient cycling.
