Genus Fufius

Neotropical burrowers from outside the tarantula family proper, small, silk-lining their shafts, and kept by almost nobody.

The frame the group supports: fossorial, patient, unremarkably venomed by everything documented, and husbanded with substrate depth plus time. Not display animals in any sense; the burrow mouth is the show.

Genus-level obscurity prices the market: a handful of sellers, no care literature, no comparable labels to anchor against. The recurring structural note applies at full strength here, because a listed price with no competing listing and no keeper record carries almost no information. Whoever buys is writing the first care sheet.
