Male and female gametes are brought together during the fertilization process, which results in the formation of a new individual. Depending on the species, this can happen either internally or externally.
How do snails fertilize internal or external?
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.
Are mollusks internally or externally?

However, some mollusks, like octopuses and squids, have reduced or internalized shells. Overall, they exhibit a wide variety of body structures, but their classification as externally or internally shelled depends on the specific type of mollusk.

How the fish do they sex and lay eggs?
Fish reproduction varies by species, but most commonly, they are either oviparous (laying eggs) or viviparous (giving birth to live young). In oviparous species, females release eggs into the water, where males fertilize them externally. Some species exhibit unique behaviors, such as nest building or guarding, to protect the eggs. In contrast, viviparous fish, like some sharks and guppies, nurture their young internally until they are ready to be born.

Agnatha fertilize how internal or external?
Agnatha, which includes jawless fish like lampreys and hagfish, typically fertilize externally. During spawning, females release eggs into the water, where males then release sperm to fertilize them. This method of external fertilization is common among many aquatic species, allowing for a larger number of gametes to be released simultaneously. However, some species may exhibit variations in their reproductive strategies.
