Laniatores
Laniatores is an infraorder within the arachnid class, specifically part of the order Opiliones, also known as harvestmen or daddy longlegs. Laniatores species are characterized by their robust body structure and enlarged chelicerae (mouthparts) that resemble fangs, which differentiates them from other Opiliones infraorders. They are found worldwide in diverse habitats, including forests, grasslands, caves, and even urban environments. Laniatores species display a wide range of behaviors, such as communal living, parental care, and complex courtship rituals. Many Laniatores species have specialized setae (hair-like structures) or spines on their bodies, which they use for sensory purposes, defense, or prey capture. Some species are known to produce silk, although not as extensively as other arachnids like spiders. The infraorder Laniatores includes several families, such as Assamiidae, Grassatores, Gonyleptidae, Phalangodidae, and Phalangodoididae, among others. Each family has its unique features and characteristics. For example, species in the family Gonyleptidae are known for their large size and intricate body patterns, while those in the family Phalangodidae tend to be smaller and have a more uniform appearance. In summary, Laniatores is an infraorder of Opiliones arachnids characterized by their robust body structure, enlarged chelicerae, diverse behaviors, specialized setae or spines, and wide geographic distribution.
