What animal is not born alive?

Some animals are born in an egg and then hatch, while others come out of their mother’s body as a fully-formed baby. Animals that are born alive include mammals, reptiles, amphibians, fish, and most birds.

Animals that are not born alive but instead come out of an egg are called oviparous animals. Examples of oviparous animals include chickens, reptiles, amphibians, fish, and most birds. It is also important to note that some animals have adaptations to make sure the eggs are taken care of even after they have been laid.

For example, some birds use their saliva to coat the eggs and create a hard shell to protect them.

In short, animals that are not born alive are those that are oviparous, meaning they come out of an egg. Examples of these animals include chickens, reptiles, amphibians, fish, and most birds.

What animals born alive or hatch from eggs?

Animals that are born alive or hatch from eggs include mammals like humans, cats, dogs, horses, and cows; reptiles like snakes, turtles, and lizards; birds like chickens, ducks, and geese; amphibians like frogs and salamanders; and fish and invertebrates like crabs, crayfish, and starfish.

In some cases, these animals are born in a larval or pre-adult form, and metamorphose (undergo physical development) into their adult form. Some insects, such as butterflies and moths, go through a similar process, emerging as adults after hatching from eggs.

Do any snakes give live birth?

Yes, some snakes do give live birth. However, these species are relatively rare and mostly restricted to some of the advanced species of snakes. Live birth is known as ovoviviparity and is seen in some species of boas, pythons, and vipers.

In ovoviviparity, eggs are formed in the female oviduct, but they hatch inside the female’s body and the baby snakes are born live, rather than hatching from eggs that are laid. This type of reproduction often occurs under harsh conditions, when the maternal environment is too cold or too dry to support egg incubation and hatching.

It also helps the babies to be more developed at birth, especially when compared to species that lay eggs and abandon them. Generally, these live-bearing snakes give birth to litters of 2-15 young, with the exception of some viper species where litters of up to 50 snakes have been reported.

Which animals is born alive by its mother?

Most animals are born alive by their mother. Examples include mammals such as cats, dogs, horses, and humans, as well as birds such as chickens, ducks, and geese. Fish and amphibians such as frogs and salamanders are usually born as eggs that need to be incubated and eventually hatched.

Reptiles such as snakes, lizards, and turtles, usually lay eggs that hatch over a period of time. Invertebrates such as spiders, crabs, and insects, generally hatch from eggs too. Some invertebrate species, however, follow different strategies such as releasing larvae directly into the environment or caring for the larvae within their body until they hatch.

Therefore, it depends on the type of animal as to whether they are born alive by their mother or not.

Do birds hatch from eggs or are they born alive?

Birds typically hatch from eggs. Most bird species lay eggs which, after an incubation period, hatch into young birds. The incubation period varies depending on the species of bird. For example, a eagle can take anywhere from 45 to 55 days to hatch, while the American Goldfinch takes 12 to 14 days.

During the incubation period, the embryos of the eggs develop and form from a single cell. After hatching, the young birds must learn how to survive and take care of themselves. In some cases, they are cared for by parents.

Some birds are even born alive, if the parents cannot provide enough warmth for the eggs to properly incubate. Such ‘precocial’ species include ducks and chickens. To protect the eggs, these birds lay their eggs in nests close to the ground that can provide humidity and heat.

As the birds hatch, they are ready to swim, walk, and even feed themselves.

How do whales make babies?

Whales, like all mammals, reproduce through sexual intercourse. Typically, a male whale will swim up to a female in a process called “courting” and engage in a mating ritual. If the female whale is receptive, the two whales will come together to mate.

The male whale will then deposit sperm into the female’s reproductive tract and the sperm will then travel to the female’s oviducts. The female whale will then ovulate and the egg will be fertilized.

The fertilized egg will then attach itself to the walls of the oviducts, where it will grow and develop until it is ready to be born. Depending on the species of whale, this process can take anywhere from 10 months to 17 months.

Whales typically give birth to one baby at a time, although twins have been known to occur. After the baby is born, the mother whale will use her milk to feed and care for the baby until it is ready to swim and hunt for food on its own.

Can a human get pregnant with a whale?

No, it is not possible for a human to get pregnant with a whale. The reproductive systems of humans and whales are too different, and they are not able to interbreed. The reproductive organs of whales are located internally and they reproduce via internal fertilization; while humans reproduce via external fertilization, with the reproductive organs located outside the body.

Additionally, the sperm and eggs of the two species are not compatible.

Do whales mate forever?

No, whales do not mate forever. Whale mating behavior is very complex and involves a lot of variation between different species and even within a species. Generally, male and female whales will come together for a short time for courtship, mating, and possibly raising offspring.

However, after mating and raising offspring, the pair often separates and the females will join with another male when they are next ready to reproduce. This cycle will continue with different partners throughout the whale’s life.

Which male animal can birth babies?

Certain species of sea creatures have the ability to give birth to babies, even though they are male. Examples of this include the seahorse and the California sea slug. Seahorses have a unique reproductive capability, in that the male is the one who actually gives birth to the baby seahorses.

When a female seahorse lays her eggs inside the male’s brood pouch, he fertilizes them and will carry the eggs for around 21 to 28 days before giving birth to up to 2000 tiny baby seahorses! The California sea slug is a species of hermaphroditic marine slug, meaning that both males and females possess reproductive organs.

When individual sea slugs mate, both take on the role of male and female. The female deposits eggs into the male’s mate pouch, and then the male will take on the task of carrying the eggs to term and giving birth to the hatchlings.

Do male whales have balls?

Yes, male whales have external testicles located near their abdominal wall. The size and shape of a whale’s testicles vary among different species and can grow as large as those of an elephant. In species like the fin whale, testicles can reach up to 15.6 kg in weight.

Although it is uncommon for such enormous testicles to be able to remain afloat, in some whales, the sea has evolved to keep the testicles close to their bodies. As a result, male whales have the ability to produce and retain sperm for up to ten months.

In some species of whales, a corpus spongiosum—a bundle of connective tissue and nerves surrounding the urethra—may also develop, as well as a penis. This may or may not be used for reproductive purposes, depending on the species of whale.

What is a male baby whale called?

A male baby whale is referred to as a calf. The term calf is commonly used for any young whale, regardless of their gender. Male calf whales will usually stay with their mother for an extended period of time, usually for at least one year, before separating and eventually forming their own families.

During this time, the calf will rely on its mother for nutrition and protection from predators.

Are there animals that lay eggs and give birth?

Yes, there are animals that both lay eggs and give birth. These animals are referred to as ovoviviparous animals, and they use a combination of methods to reproduce.

Ovoviviparity is an evolutionary adaptation that allows an animal to produce young whether it is favorable to lay eggs or give birth. For example, some sharks have this type of reproductive strategy, where the embryos develop inside a special egg case that is held inside the mother’s body, but the pups are born alive instead of hatching from the egg.

This is beneficial to the mother shark because all of her energy is not spent in one reproductive effort, unlike with viviparity, where her food and energy is completely spent on giving birth to live young.

Other animals that are ovoviviparous include certain zebra fish, frogs, snakes and lizards, hammerhead sharks, and elephant shrimps. These animals are unique because they are able to be flexible when it comes to reproducing and can shift between egg-laying and giving birth, depending on the conditions they are facing.

What animals lay eggs to have babies?

Many different animals lay eggs to have babies. There are a variety of animals from a whole range of groups, including amphibians, reptiles, fish, birds, and even some mammals such as monotremes, like the duck-billed platypus.

Amphibians such as frogs, toads, and salamanders lay eggs in water, usually in foam nests made by the female, and once hatched, these eggs will have developed into tadpoles, also known as froglets. Reptiles such as snakes, lizards, and turtles lay eggs in a secure burrow or hidden site and the baby reptiles will hatch from the egg fully formed.

Fish also lay eggs, with some species laying large numbers of small eggs or fewer but larger eggs, depending upon the species. Female birds lay eggs, typically one at a time over a period of days, and are often brightly colored or patterned.

Monotremes are the only mammals to lay eggs, with the two species of egg-laying mammals, the platypus and the echidna, found in Australia and New Guinea.

What are the 5 mammals that lay eggs?

The five mammals that lay eggs are:

1. Platypus: Found in Eastern Australia and Tasmania, platypuses are among the only mammals that lay eggs, typically laying between two and six eggs in a burrow near a freshwater source.

2. Four-legged echidna: These spiny, hedgehog-like creatures are found in Eastern Australia, Tasmania, New Guinea and some parts of Indonesia. They typically lay a single egg into a pouch, where the egg hatches after about 10 days.

3. Short-beaked echidna: This mammal is found in Australia, New Guinea and on some smaller islands in the Indonesian archipelago, and it lays a single egg into a pouch.

4. Long-footed potoroo: This small marsupial, found in eastern Australia, typically lays one egg which hatches after 17 or 18 days.

5. Duck-billed platypus: Found mainly in eastern Australia and Tasmania, they lay between one to three eggs, which hatch after 10 to 14 days.

Do egg-laying mammals exist?

No, there are no egg-laying mammals. Mammals are warm-blooded animals that nourish their young with milk from mammary glands, and mammals do not lay eggs. The only living egg-laying mammals are monotremes- a very small group of mammals that include the platypus and the echidna.

Even these species lay a soft-shelled egg, not a hard-shelled egg like those of birds and reptiles. For example, the echidna lays a single large leathery egg encapsulated in a thin shell. Monotremes lay their eggs in small burrows they create or sometimes in other burrows they find.

The eggs are left to incubate and the eggs hatch after about 10 days. Monotremes are the only living example of egg-laying mammals. All other mammals, such as marsupials, rodents, cats, whales and primates, give birth to live young.
