Raccoons exhibit internal fertilization. This means that the male raccoon deposits sperm inside the female's reproductive tract, where fertilization of the eggs occurs. This method is typical among mammals, allowing for the development of the embryo within the female's body.
External fertilization
Mollusks exhibit various types of fertilization, primarily external and internal. In external fertilization, eggs and sperm are released into the water, where fertilization occurs, common in many marine species like bivalves and gastropods. In contrast, some mollusks, such as cephalopods, engage in internal fertilization, where the male transfers sperm directly to the female. The method of fertilization varies among different mollusk classes and influences their reproductive strategies and development.
Sharks have internal fertilization through the use of a clasper.
The type of fertilization associated with fish is external fertilization. External fertilization happens when the sperm and egg meet outside of the body. Female fish will lay the eggs and the males will come along and fertilize them.
