Sinkhole Spider
The ground gives way. That is the first and sometimes last thing a traveler notices. One moment you are crossing open desert east of Vegas City; the next, the sand collapses beneath your weight and something is pulling inward. Not downward. Inward, like a fist closing.
The Sinkhole Spider is a burrowing ambush predator roughly the size of a grown man. It digs beneath the surface and spins a web not between anchor points but between its own legs, creating a living trap spread across the sand. When it feels motion above, typically footsteps, wheels, or the shuffling gait of a wandering zombie, it draws its legs inward with sudden force. The web contracts. The prey drops. What follows is methodical: the spider injects a necrotic venom that slowly rots the victim's flesh, tenderizing the catch for consumption over the following hours or days. The spider is not in a hurry. It has nowhere to be.
Dieseljock clans traveling east of Vegas City have particular cause to curse these creatures. A vehicle tire catching the edge of a Sinkhole Spider's trap is a common enough occurrence that experienced drivers learn to read the sand for subtle depressions and avoid terrain that looks too smooth, too flat, too inviting. The spider's concealment is nearly perfect. By the time you know what is underneath you, you are already inside the web.

Basic Information
Ecology and Habitats
Sinkhole Spiders occupy the desert flats east of Vegas City, preferring loose, sandy soil that supports their burrowing lifestyle. Their diet is opportunistic: travelers, desert lizards, and even wandering undead have been found in various stages of necrotic decomposition inside collapsed trap sites. The spider does not discriminate. If it walks above the web, it is food.
Their ambush-only hunting strategy means Sinkhole Spiders are essentially invisible until triggered. This makes population estimates unreliable and territory mapping a matter of educated guesswork supplemented by the hard experience of those who have lost boots, tires, or companions to the sand. The necrotic venom suggests a relationship with decay-based organisms in the desert ecosystem, though whether this is adaptation or coincidence remains a question no one has been funded to answer.
