how does fertilization in a bird differ from that in fish

an egg is the organic vessel containing the zygote in which an embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an egg cell. Most arthropods, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not.

fish reproductive organs include testes and ovaries. In most species, gonads are paired organs of similar size, which can be partially or totally fused.[1] There may also be a range of secondary organs that increase reproductive fitness. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm or eggs are released; the sex of a fish often can be determined by the shape of its papilla.

Answer:
- Hen and other birds lay eggs on land in their nests. So they are covered by a thick shell for protection from dehydration and predators.

- Fish eggs are laid in large numbers in the water. They do not get dehydrated as they are already in water. So they are only covered by a thick jelly and not a shell.

- A hen’s egg, when fertilized, will produce a chicken. A fish egg will produce a fish.
