Reproductive system of mollusks
Mollusks, a diverse group of animals including snails, clams, and octopuses, have various reproductive systems. Most exhibit sexual reproduction with separate sexes, while some are hermaphrodites, containing both male and female reproductive organs. They typically produce eggs, which may develop externally in water or internally, depending on the species. Some mollusks show unique behaviors, like internal fertilization, where sperm is transferred directly between individuals. Others release sperm and eggs into the water for external fertilization. The reproductive strategies vary widely, contributing to their adaptability and survival in different environments.
