## Abstract Phospholipase activity of eggβwater treated __Arbacia punctulata__ and __Lytechinus variegatus__ sperm was shown to result from the sequential action of phospholipase A and lysophospholipase. A transient burst of phospholipase A activity followed induction of the acrosome reaction with

The antigenic composition of the sperm surface in Para. centrotus lividus Lain. and Sphaereehinus granularis Lain. was studied using the sperm agglutination test with homologous and heterologous antisera. The results indicated that sperm of both species have at least one antigenic determinant locate
To determine the fate of the sperm tail during fertilization, the microtubules of the incorporated axoneme are measured using a monoclonal antibody against acetylated a-tubulin in zygotes from the sea urchin Strongylocentrotus purpuratus. This antibody recognizes axonemal microtubules, but does not
## Abstract In this study we used Triton Xβ100 extracted sea urchin spermatozoa to investigate the mechanical behavior of the basic 9+2 axoneme. The dynein motors were disabled by vanadate so that the flagellum is rendered a passive structure. We find that when a proximal portion of the flagellum i
