## Abstract A sperm‐activating substance (SAS) was obtained from the jelly coat of sea‐urchin ova and its chemical properties were investigated in three seaurchin species. The SAS was partially purified from the jelly coat of __pseudocentrotus__ eggs through several steps of purification by procedu

## Abstract After fertilization the sea urchin sperm nucleus transforms into the male pronucleus which later fuses with the female pronucleus re‐establishing the diploid genome of the embryo. This process requires remodeling of the sperm chromatin structure including the replacement of the sperm hi

## Abstract Decreased glycogen radioactivity was followed as an indicator of glycogen utilization following activation of __Strongylocentrotus purpuratus__ eggs. Within 15 minutes of exposure to sperm or ammonia, egg glycogen radioactivity decreased. The level of radioactivity in control (unfertili
## Abstract “Fertilization acid” is released from sea urchin eggs upon fertilization and decreases the pH of the surrounding seawater. In bicarbonate‐free artificial seawater flushed with nitrogen gas, the pH shift still occurs but returns to the original value in a few minutes, suggesting that the
