Cephalodiscus gilchristi is a sessile hemichordate belonging to the order Cephalodiscida. It is found in South Africa in 1908.

Parasites

The parasitic copepod Zanclopus cephalodisci has been found in the intestines of Cephalodiscus gilchristi.

Isolated molecules

Cephalostatin-1, is a steroidic 13-ringed pyrazine with the empirical formula C₅₄H₇₄N₂O₁₀ that was isolated from Cephalodiscus gilchristi. It is a potent anti-cancer agent that causes cell death in the subnanomolar to picomolar ranges via an atypical apoptosis pathway.
