What is the term for external fish reproduction where eggs are released and sperm is exuded over the eggs?
This is called oviparity or spawning.
Are ants oviparous?
Oviparity describes an animal that lays eggs with little to no embryonic development in the mother. Then, yes, bees are oviparous.
What is it called when an animal lays eggs rather than gives live birth?
It is called oviparity. Animals which exhibit this behaviour are known as oviparous.
Why did oviparous evolved into viviparous?
The two reasons for vertebrates to evolve from oviparity ( Egg-laying) to viviparity (Giving live birth) are :- 1. To increase the number of successful births as in viviparity the offspring is protected by the mother whereas in oviparity eggs laid can easily be eaten by other animals. Hence viviparity is selected by natural selection and they evolved to viviparity. 2.In oviparity the youngs developed are mostly poor as no care is given by the mother. In viviparity the youngs get full care from the mother in terms off oxygen and nutrients so the youngs developed are more healthy in viviparity. So they were selected by natural selection and were evolved to viviparity.
Do all sharks give birth to their young alive?
Most sharks are ovoviviparous. The young are born live. However, some are Oviparity. These are species that do lay eggs. Examples would be, the horn shark, catshark, Port Jackson shark, and swellshark.
What is the meaning of ovaviviparious?
Ovoviviparous means that an animal sort of combines viviparity (bearing live young after gestating with placental transfusions) with oviparity (egg-laying). Basically its like laying eggs but the mother keeps the eggs inside her body, so there's no nutrient flow between mother and offspring like there is for placental animals.
How do tarzan chameleons reproduce?
Tarzan chameleons reproduce through oviparity, meaning they lay eggs. After mating, the female typically lays a clutch of eggs in a burrow or a secure location. The eggs incubate for several months before hatching, with the young chameleons emerging fully formed and independent. This reproductive strategy allows the species to thrive in their natural habitats.

What seems to be the most probable reproductive method and least probable method for oviparous?
The most probable reproductive method for oviparous organisms is external fertilization, where eggs are fertilized outside the female's body, commonly seen in many fish and amphibians. The least probable method would be viviparity, where embryos develop inside the mother and are born live, as this contradicts the defining characteristic of oviparity, which involves laying eggs.
Do chondrichthyes have an amniotic egg?
No, chondrichthyes, which include sharks, rays, and skates, do not have an amniotic egg. Instead, many species of chondrichthyes reproduce through methods such as oviparity (laying eggs) or viviparity (live birth), with some species having adaptations like the development of embryos in a protective environment within the mother's body. The amniotic egg is characteristic of reptiles, birds, and some mammals, which allows for reproduction in terrestrial environments.
