How do cyclostomata reproduction?

Answer 1

Cyclostomata, which includes jawless fish like lampreys and hagfish, typically reproduce through external fertilization. Most species undergo spawning, where females release eggs into the water, and males simultaneously release sperm to fertilize them. This process often occurs in freshwater or marine environments, depending on the species. Some lamprey species also exhibit a more complex life cycle, with larval stages that live in sediment before transforming into adults.
