Google “sea urchin fertilization” and you’ll find dozens of animations and videos of lone sea urchin sperm finding its way home to an egg. Why the plethora of sea urchin sex tapes?

Researchers have identified a key enzyme in sea urchin egg fertilization. Working on two species of urchins, Strongylocentrotus purpuratus and Lytechinus variegatus, Gary Wessel and others at Brown ...

The purple sea urchin has been the most closely studied ... Scientists found that the key to species-specific fertilization is a sperm protein called bindin connecting with the correct receptor ...

In 1874 the German zoologist Oscar Hertwig studied fertilization of sea urchin eggs. Sea urchins are relatives of starfish and sand dollars, abundant near seashores, and still favorites among ...

We now present kinetic evidence for at least one intermediate stage in the fertilization of sea urchin eggs.

Researchers identified a species of sea urchin with a relatively short breeding ... embryonic development and even the act of fertilization were easily viewed with microscopes in the 1800s.

Study Says") The urchin's usefulness as a model for developmental biology was another major reason for the sequencing project. Scientists have long used sea urchins to study fertilization and ...
