Egg jelly Egg jelly Egg jelly(extracellular layer", "jelly coat) is a gelatinous layer that surrounds the oocytes of many organisms and releases species-specific chemoattractants that activate and guide sperm to the oocyte.

These short peptides diffuse into the surrounding area and stimulate respiration and movement of the sperm to the egg. An example of such a peptide is resact which has been studied as the primary means of attracting and orientating sperm to the eggs in sea urchins. The
