Summary The ultrastructure of the acrosome reaction in the sperm of the teredo, Bankia australis, is described. In brief, the reaction consists of three phases: (a) formation of a bleb and membrane fusion, (b) disappearance of the longitudinally oriented fibrils, and (c) outward flaring and disappearance of the osmiophilic granule. The osmiophilic granule appears to consist of prism-like structures. The axial rod never lengthens during the acrosome reaction.
