Sea urchin sperm-egg interactions studied with the scanning electron microscope.

Tegner MJ , Epel D .


???displayArticle.abstract???
Scanning electron microscopy of the outer surface of sea urchin eggs sampled at intervals during the first 3 minutes after insemination reveals the detailed structural changes of the vitelline layer during its transformation into the fertilization membrane. A sperm attachment-detachment sequence is described for the large number of sperm which transitorily bind every egg during fertilization.
