Sea urchin eggs fixed in a glutaraldehyde‐calcium chloride mixture have “micropapillae” with a dense content. If these structures are real, they are likely to be sites where a fusion with the spermatozoon can take place. It is possible however that they represent some kind of preparation artefact without a structural counterpart in the living state.
