A case of acardius acephalus in a Macaca fascicularis is reported. This congenital anomaly occurs only in multiple‐birth gestations (most commonly monozygotic twins). Artcry‐to‐artery and vein‐to‐vein anastomoses appear to be a constant feature. This condition is very rare in man and probably even more so in monkeys. Classification and theories on etiology are discussed.
