I need five animals that have internal fertilization and five that have external fertilization

Internal Fertilization:

Humans, Dogs, Cats, Horses, Monkeys, Whales, Lions, Bats

External Fertilization:

Fish, Birds, Most Insects, Reptiles. (mostly anything that lays eggs)

Internal fertilization:dogs,cats,elephants, seals, dolphins

External fertilisation: fish, toads,frogs, dragonflies, sea urchins

Explanation:

All mammals have internal fertilization that is require the insertion of the male sex organ into the female sex organ and the egg is fertilised within the animal's body.

External fertilization is when the sperm is released outside of the body over the female eggs which are also released in the external environment.
