Cyclocosmia latusicosta — Vietnamese Oreo Butt Trapdoor Spider
Nature occasionally produces something so bizarre, so perfectly engineered, that it looks like it was designed by an artist rather than evolution. Cyclocosmia latusicosta, the Vietnamese Oreo Butt Trapdoor Spider, is exactly that. The abdomen of this extraordinary mygalomorph is truncated into a hardened, disc-shaped plug — intricately patterned with radiating ridges and grooves that look uncannily like an Oreo cookie. This disc isn’t decorative. It’s a shield.
When threatened, Cyclocosmia retreats into its trapdoor, which is formed by the disc-shaped abdomen. The trapdoor helps conceal the spider and protect it from predators. This species is native to Vietnam and is part of the mygalomorph family, known for their robust build and unique behaviors.

The spider arrived quickly and was well-packaged. It’s fascinating to see how the abdomen forms a natural trapdoor. I’ve been observing it for a week and it seems to be adjusting well to its enclosure. Would recommend to anyone interested in unusual arachnids.
