internal because they give eggs and so they have a internal fertilisation
internal fertilization is, by definition advantageous because it is natural. In Vitro fertilization is advantageous for those who cannot have children naturally because it allows the miracle of birth to occur.
An ostrich lays eggs after the mating ritual. Therefore, the fertilization process is internal.
They are external because they are never looked after. that doesnt make sense i think a cod is internal

Internal because they give birth and not lay eggs. If they lay eggs, they would be like a chicken. ~Savannah B.
Internal and external beccause if you think it can give birth to eggs and lay eggs but people think it is internal because they dont think properly
Tigers have Internal Fertilization. (occurs inside the body). Tigers copulate frequently and noisily and repeatedly for 5 or 6 days. Each usually take about 20 to 30 seconds. Then the gestation period is 16 weeks.
Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.
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.
Usually, it doesn't. The only thing that would be different is that internal fertilization, there is less eggs because they are protected in the mother's body. The external fertilization, there is more eggs because of the lesser chance of survival
It is external because we all know that fish lay eggs and they lay eggs in their habitat so its meant to say that the fish, develop their embryo inside the egg and also where it is hatch.
