The existing literature concerning reproduction of snow crab(Chionoecetes opilio) is critically reviewed and discussed inthe context of recent conceptual paradigms and ongoing research.The functional anatomy of the male and female reproductive systemsis presented and interpreted in terms of the various matingpathways available to this species. Hypotheses to account forimmediate and delayed fertilization are presented. The possibleadaptive values of spermatophore storage and a novel mechanismfor ensuring last male precedence are explored. In additionto critical gaps in our understanding of reproduction in snowcrab and other brachyurans, ambiguities in current conceptsand terminology are highlighted. Directions for future researchwhich addresses central problems of snow crab reproductive biologyare suggested. 相似文献
