Snails can either fertilize internally or externally, depending on the species. Most terrestrial snails, such as garden snails, engage in internal fertilization, where the male transfers sperm to the female's reproductive tract during mating. In contrast, some aquatic snails may practice external fertilization, releasing eggs and sperm into the water simultaneously for fertilization to occur. This variation in fertilization methods is influenced by their respective environments and reproductive strategies.
External
yes
Bluegills have internal fertilization, where the male releases sperm inside the female's body to fertilize her eggs.
Internal
they have external fertilization , PS i learned it in science :P zz this is all wrong...it does NOT use exernal fertilization...external fertilazation is for fish and stuf,but internal is for humans and mamals.
externally
Some snails can self-fertilize, such as Helix aspersa, but not all snails can.
All birds fertilize their eggs internally. A male bird has to mate with a female in order for a fertilized egg to be produced.
Snails are hermanphrodites but they will not self-fertilize. Only plants do that.
Lobsters use external fertilization. I don't know how just yet but I am trying to find out. I had this question for homework once and it is hard to find the exactanswer you are looking for.
Bald eagles fertilize internally. After mating, the female eagle stores the male's sperm in her body, which allows her to fertilize her eggs internally before laying them. Once fertilized, the eggs are laid in a nest and incubated until they hatch.
Internal fertilization and external fertilization. Internal fertilisation means fertilize the egg inside the female's body. External fertilization is fertilize the egg after the female had lay it out. All mammals including platypus and spiny anteater do internal fertilization.
