What animals are internal fertilization?

Internal Fertilization

This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds. Reptiles and insects produce leathery eggs, while birds and turtles produce eggs with high concentrations of calcium carbonate in the shell, making them hard.

Which animal does not occur internal fertilization?

Answer: C) Fish does not occur internal fertilization .

Is dog external or internal fertilization?

Internal fertilization is when the eggs are kept within the reproductive tract of the female, but when a the males sperm is inserted the egg gets fertilized inside the female. This occurs most often in land-based animals. Examples include worms, cats, dogs, birds, mammals, squid, arthropods, sharks and reptiles.

Do reptiles have internal fertilization?

Most reptiles reproduce sexually and have internal fertilization. Males have one or two penises that pass sperm from their cloaca to the cloaca of a female. Fertilization occurs within the cloaca, and fertilized eggs leave the female's body through the opening in the cloaca.

Is fish internal or external fertilization?

Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them.

Do chickens have internal or external fertilization?

Chickens — like other birds — lay fertilized eggs via sexual reproduction.

Do mammals have internal fertilization?

In mammals, fertilization takes place internally in the protected environment of the ampulla of the oviduct, as opposed to external fertilization where sperm and egg meet outside the parent's body (e.g., as in fish, reptiles, amphibians and invertebrates).

What animals undergo internal and external fertilization?

This occurs in some bony fish (like the guppy Lebistes reticulatus), some sharks, some lizards, some snakes (such as the garter snake Thamnophis sirtalis), some vipers, and some invertebrate animals (like the Madagascar hissing cockroach Gromphadorhina portentosa).

Do frogs have internal or external fertilization?

In most species of frogs, fertilization is external. The male frog grabs the female's back and fertilizes the eggs as the female frog releases them (Figure 2.2B). Rana pipiens usually lays around 2500 eggs, while the bullfrog, Rana catesbiana, can lay as many as 20,000.

Do amphibians have internal fertilization?

Amphibians reproduce sexually with either external or internal fertilization. ... Amphibians do not produce amniotic eggs, so they must reproduce in water. Amphibian larvae go through metamorphosis to change into the adult form.

Do bryophytes show internal fertilization?

Fertilization in bryophytes or pteridophytes is considered as a internal fertilization because fusion of male and female gametes (syngamy) occurs inside the archegonium (female reproductive organ).

Do birds have internal Fertilisation?

Birds. Most birds do not have penises, but achieve internal fertilization via cloacal contact (or “cloaca kiss”). In these birds, males and females contact their cloacas together, typically briefly, and transfer sperm to the female.

Do cats have internal or external fertilization?

When we think about organisms mating, often we think of animals around us—humans, dogs, dragonflies, cats, lizards, or maybe birds. When these animals mate with each other, the egg and sperm meet inside the body, not outside in the air or water.

What animals have external fertilization?

Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.
