Immature oocytes from starfishes were obtained during the breeding and non‐breeding seasons. The oocytes were “fertilized” without previous induction of maturation by 1‐methyladenine (1‐MA) or germinal vesicle breakdown (GVB). Elevation of the fertilization membrane (FM) was observed with eggs obtained during the breeding season, but not observed with eggs obtained during the non‐breeding season. Abnormal development was observed when these “fertilized” eggs with a FM were subsequently treated with 1‐MA. The results of these experiments indicated that the elevation of FM was independent of GVB or the mixing of nuclear and cytoplasmic components.
