What kind of method of fertillization does the Agnatha do?

Agnatha, which includes jawless fish like lampreys and hagfish, typically use external fertilization. In this process, females release eggs into the water, and males then release sperm to fertilize them externally. This method often occurs in freshwater or marine environments, where the eggs and sperm are released simultaneously to increase the chances of successful fertilization. Some species may exhibit varying behaviors related to spawning, but external fertilization is the general method used by this class.
