Do rattlesnakes internal or external fertilization?

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).

Which animals use 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.

How do snakes reproduce sexually?

When snakes mate, the male snake extends his hemipenes, two organs that come out of the cloaca, and fertilizes the eggs inside the female. The female snake and the male snake may stay joined for as long as one day, though it is usually over in about an hour. ... After mating, the eggs need to develop in the female.

Does external fertilization take place in reptiles?

In oviparity, fertilized eggs are laid outside the female's body and develop there, receiving nourishment from the yolk that is a part of the egg. This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds.

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 all animals have internal fertilization?

Internal Fertilization

This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds. ... Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young.

What is external fertilization explain the process with an example?

external fertilization is a case in which fusion of male and female gametes takes place in outside environment/ medium and not in the body of the female . for example, in case of frogs , fertilization takes place in water medium . the female releases eggs in the water at the same time sperms are released too.

Is Dog 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.

Can rattlesnakes reproduce asexually?

Timber rattlesnakes have a very complex reproduction cycle, as do most animals. They undergo sexual reproduction only and are dioecious, meaning that males and females exist as separate individuals.

Can snakes reproduce without a mate?

While some snakes lay eggs in a nest, others keep them inside their bodies until they hatch. Either way, female snakes don't necessarily need a mate to produce eggs. ... Surprisingly, a single snake who's never been bred with a male can give birth to viable young which she can fertilize all by herself.

Do snakes give birth through their mouth?

There is a common misconception that snakes give birth through their mouths. This is not true: Snakes do not give birth through their mouths. However, not all species of snakes give birth the same way. The way that a female snake delivers her babies depends on the species of snake.

Where does external fertilization occur?

External fertilization in animals usually occurs in water or in damp areas in a process called spawning. Moisture in the environment keeps the gametes from drying out. Moisture is also important so the eggs and sperm can move around freely, which lets them meet and fuse.

Where does internal fertilization occur?

Internal fertilisation occurs inside the female body. The male gamete enters the female body and fuses with the egg in the female body itself.

In which of the following does external fertilization take place?

External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. Many fish, amphibians, and other sexual aquatic animals use external fertilization (the exceptions are aquatic mammals, sharks, and some other special types of fish).
