Internal fertilization occurs inside the female's body, where sperm fertilizes the egg, while external fertilization occurs outside the body, usually in water, where eggs are fertilized by sperm. Internal fertilization is common in land-dwelling animals, while external fertilization is common in aquatic animals. Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
Some animals that have external fertilization include fish, frogs, sea urchins, and certain aquatic invertebrates like jellyfish and corals.
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.
A gorilla is an external animal, meaning it has its organs and bodily functions on the outside of the body, like most animals.
The external structure of animals refers to the physical characteristics, such as body shape, size, color, and appendages, that are visible on the outside of their bodies. These features can vary greatly among different species and are adapted to help the animals survive in their specific environments. Examples include fur for warmth, wings for flight, or camouflage for blending in with surroundings.

Ants, beetles, fish and frogs are the main ones.
There are broadly 2 types of fertilisation - 1) Internal fertilisation - This mostly takes place in higher classes of animals like humans and mammals. In this the male transfers its gametes into the female body and the male gamete fuses with the female gamete inside the female body 2) External fertilisation - This is mostly seen in fishes. The male and the female both transfer their gametes into the external environment and the gametes fuse outside
Some examples of animals that undergo external fertilization include fish, amphibians, and many invertebrates such as sea urchins and corals. External fertilization occurs when eggs and sperm are released into the environment where they meet and fertilize outside of the body.

external fertilisation. some of them reproduce by internal fertilisation. the male ejects sperm out of its reproductive organ. the female ejects its ova through its reproductive organ. both of them meet in the water as they float by. there are chances of many water animals of the same species having the same father as more sperm is given out.

In humans and mice fertilisation is internal and the chance of fertilisation is more.But in frogs and those which lay eggs externally,the chance of fertilisation is less since they are prone to destruction.Inorder for their survival,they lay more no. of eggs than needed
