External Fertilization – An Overview
External fertilization occurs in fish, frogs, and certain invertebrates like sponges. External fertilization is the process of reproduction where the fusion of the male gamete and female gamete takes place outside the body in an external environment. This type of reproduction has various benefits as it has great biodiversity and the chances of survival are also higher. In this article, we will study the process of external fertilisation, examples, features and more.
