Arachnida Mygalomorphae is a suborder of spiders that includes some of the largest and most primitive arachnids found in the Comunidad Valenciana region. These spiders are known for their robust build and significant presence in various ecosystems.

Characteristics:

• Size: Mygalomorphae spiders are generally larger than other spiders, with some species reaching sizes of up to 30 cm, including leg span.
• Appearance: They have a heavy body and are often characterized by their hairy exteriors. Their chelicerae are oriented downward rather than sideways, which is typical of more primitive spiders.
• Fangs: These spiders possess strong, downward-pointing fangs that they use to subdue prey.
• Behavior: Mygalomorphae tend to be less active hunters, often relying on a sit-and-wait approach to catch their prey.
• Habitat: They prefer a variety of habitats ranging from burrows in dry, sandy areas to moist, forested regions.

Species in Comunidad Valenciana:

• The Lycosa tarantula, commonly known as the "Mediterranean Tarantula," is one notable species found in this region.
• Another local species is the Atypus affinis, known for their unique silk-lined burrows.

The presence of Mygalomorphae in the Comunidad Valenciana highlights the region's diverse biodiversity, contributing to its rich natural heritage. Their existence is vital for maintaining the ecological balance, as they play a crucial role in controlling insect populations.
