Mygalomorphae

Mygalomorphae is a subgroup of spiders known for their large, robust bodies and downward-facing fangs that strike vertically. This group includes tarantulas and trapdoor spiders. They typically have two pairs of book lungs for breathing, and their eyes are often small and clustered. Mygalomorphs tend to be more primitive compared to other spiders and generally have longer lifespans. They usually live in burrows or hidden retreats and rely on patience and ambush for hunting. Their evolutionary traits give them distinctive features that set them apart within the spider family.
