Birds are not ovoviviparous; they are oviparous, meaning they lay eggs that hatch outside the body. Ovoviviparous animals, such as some species of sharks and reptiles, retain the eggs inside the body until they are ready to hatch.
No. Ovoviviparous means that the female produces eggs which hatch inside her body, meaning she actually gives live birth. Platypuses are oviparous, which is quite different from being ovoviviparous. They lay eggs, and incubate them for ten days.
No. seahorses are ovoviviparous...meaning they produce eggs but their eggs are in the placenta rather than being outside the body!
Birds, monotremes, most reptiles and amphibians are oviparous.
