The Center's public exhibits include a touch tank where visitors can touch small marine invertebrates such as sea stars and sea urchins in a shallow pool, an aviary for the center's numerous seabirds with a two-story diving pool, as well as [seal]s, Steller's sea lions, and Giant Pacific octopuses.

In mammals as well as sea urchins, the sudden rise in calcium concentration occurs because of the influx of calcium ions within the egg.

The defenses are particularly well characterized in the sea urchin, which respond to the acceptance of one sperm by inhibiting the successful penetration of the egg by subsequent sperm.

The prevention of polyspermy in sea urchins depends on a change in the electrical charge across the surface of the egg, which is caused by the fusion of the first sperm with the egg.

Unfertilized sea urchin eggs have a negative charge inside, but the charge becomes positive upon fertilization.

When sea urchin sperm encounter an egg with a positive charge, sperm-egg fusion is blocked.

While much has been learned about the identity and function of the contents of the cortical granules in the highly accessible sea urchin, little is known about the contents of cortical granules in mammals.

In the well-studied sea urchin model system, the granule contents modify a protein coat on the outside of the plasma membrane (the vitelline layer) so that it is released from the membrane.
