The two most distinct species, Echinometra sp. A (Ea) wit...

Hybridization between these species was...

Sulfated polysaccharides from egg jelly are the molecules responsible for inducing the sperm acrosome reaction in sea urchins. This is an obligatory event for sperm binding to, and fusion with, the egg. The sulfated polysaccharides from sea urchin...
