Which animal is born alive by its mother?

Many animals give birth to live young (viviparous), most notably mammals like humans, dogs, whales, and kangaroos, but also some reptiles (garter snakes), fish (some sharks, guppies), amphibians (Nimba toad), and even some insects (aphids, tsetse flies, Pacific beetle cockroaches). These animals develop inside the mother, receiving sustenance, and are born as miniature versions of adults, unlike egg-layers.

Are all animals born alive from the mother's body?

Many reptiles and the vast majority of invertebrates, most fish, amphibians and all birds are oviparous, that is, they lay eggs with little or no embryonic development taking place within the mother.

What animal gives birth alive?

Animals giving birth to live young (viviparous) include most mammals (dogs, cats, humans, whales), many sharks (Leopard sharks, hammerheads), some snakes, lizards, and even some fish (guppies) and insects (aphids), showing this strategy evolved many times, though the most famous are placental mammals (like us) and marsupials.
 

Which animal is pregnant for 4 years?

The animal with a pregnancy lasting up to four years is the Alpine Salamander (specifically the black or golden variety), found in the European Alps; its gestation period varies with altitude, sometimes reaching 4 years at high elevations, making it the longest in the animal kingdom, longer even than elephants or whales. These salamanders give birth to fully developed live young, who sustain themselves by eating unfertilized eggs and the mother's uterine lining before birth, say Discover Magazine and A-Z Animals.
 

Which animal eats its mother as soon as it is born?

Crab Spiders

Once they hatch, she has no way of feeding them with trophic eggs or any other resource. As a result, the spiderlings begin consuming their mother soon after birth. This behaviour is biologically programmed and ensures the young receive the nutrition they need without any delay.

Which animal is born pregnant?

The animal famously born pregnant is the aphid, a tiny insect that reproduces rapidly through a process called parthenogenesis, where a daughter, still developing inside her mother, already has eggs inside her, leading to "telescoping generations" where babies are born pregnant with their own offspring. Other creatures, like some sharks, lizards, and even a unique type of frog (Suriname toad), have fascinating reproductive strategies, but aphids are the classic example of being born pregnant.
 

Would a lion take care of a human baby?

In rare stories or legends, lions have been said to protect or show restraint toward human children, but these are exceptional cases and not the norm for wild behavior.

What animal is pregnant the longest?

The Alpine salamander holds the record for the longest pregnancy in the animal kingdom, gestation lasting up to four years, longer than elephants or whales. Elephants have the longest gestation for mammals, around 22 months, while frilled sharks can gestate for over three years, and sperm whales for 14-16 months. 

How long are snakes pregnant?

Snake pregnancy (gestation) varies wildly by species, from a few weeks for some egg-layers to several months for live-bearers like boas (5-8 months), with some venomous snakes like copperheads carrying young for up to 9 months, as they either lay eggs (oviparous) or give birth to live young (viviparous) after internal development. The period from mating to egg-laying can also differ due to sperm storage and follicle development.
 

How long is a lion pregnant?

A lion's gestation period is about 110 to 120 days (roughly 3.5 to 4 months), during which a lioness typically carries one to four cubs, sometimes more, giving birth in a secluded den and keeping them hidden from the pride for several weeks before introducing them.
 

Which animal has male pregnancy?

The male animals that get pregnant and give birth are seahorses, seadragons, and pipefish, members of the family Syngnathidae, where the female deposits eggs into the male's brood pouch or onto his body, and he fertilizes, incubates, and gives birth to the young. This unique reproductive strategy allows females to produce more eggs while the male carries the current brood, increasing species survival chances.
 

Can snakes give live birth?

Yes, many snakes give live birth, a process called viviparity or ovoviviparity, where young develop inside the mother and emerge as live, fully formed snakes rather than hatching from eggs outside the body, common in vipers (like rattlesnakes, copperheads) and boas, helping them thrive in colder or aquatic environments. While most snakes (about 70%) lay eggs, the remaining 30% give live birth, a beneficial adaptation for protection and stable incubation. 

Which animal gives birth by mouth?

The animal most famously known for giving birth through its mouth is the extinct Gastric-Brooding Frog, where the female swallowed eggs that developed in her stomach before she regurgitated fully formed froglets, but several fish and amphibians (like Darwin's Frog, Seahorses, Cichlids) exhibit mouthbrooding, carrying eggs or young in their mouths or pouches for protection until birth. 

Which animal is pregnant by itself?

Yes, some animals can impregnate themselves through asexual reproduction, primarily via parthenogenesis (virgin birth) or, in the case of the mangrove killifish, self-fertilization as a hermaphrodite, allowing females to create offspring from their own DNA without a male, common in reptiles (lizards, snakes, dragons), sharks, birds, and fish.
 

Could a gorilla and a human have a baby?

No, a human and a gorilla cannot have a baby because they have different numbers of chromosomes (humans have 46, gorillas have 48), which prevents successful fertilization and development, making any hybrid offspring genetically impossible and nonviable due to fundamental biological incompatibilities. Even if fertilization somehow occurred, the differing genetics and vastly different physiology, gestation, and immune responses would prevent a successful pregnancy and birth, notes a Reddit post on the r/askscience subreddit. 

Why can't humans lay eggs?

Humans don't lay eggs because our ancestors evolved the mammalian trait of live birth, which provides better protection and continuous nourishment for developing young through a placenta, allowing for more complex brains and longer development, a shift from ancestral egg-laying to internal gestation favored by evolution for survival, rather than returning to eggs.
 

Is there an animal that is pregnant for 3 years?

Black alpine salamanders are amphibians that live in the Central and Eastern Alps and give birth to live young. Their pregnancies can last from two to three years, longer than elephant gestation periods, depending on the altitude at which the salamanders live. They typically bear two fully developed young.

What repels snakes immediately?

Research also shows that cinnamon oil, clove oil, and eugenol are effective snake repellents. Snakes will retreat when sprayed directly with these oils and will exit cargo or other confined spaces when these oils are introduced to the area.

Do snakes knot during mating?

Yes, snakes often "knot" or intertwine during mating, forming a temporary structure where the male wraps his tail around the female's to align their cloacas for sperm transfer, a behavior sometimes called "locking," especially common in species like garter snakes, anacondas, and pythons, sometimes in large "mating balls" with multiple males. 

What animal is constantly pregnant?

The swamp wallaby is the only mammal that is permanently pregnant throughout its life according to new research about the reproductive habits of marsupials. Unlike humans, kangaroos and wallabies have two uteri.

Do elephants menstruate?

No, elephants do not menstruate in the way humans do; instead, most female mammals, including elephants, reabsorb their uterine lining if pregnancy doesn't occur, though elephants have complex estrous cycles with hormone shifts, not regular bleeding periods like humans, apes, and some bats. Menstruation (shedding of the uterine lining) is rare in mammals, limited to a few species like primates, bats, the elephant shrew, and spiny mouse, with elephants not being among them.
 

Which animal has the shortest pregnancy?

The animal with the shortest pregnancy is often cited as the Virginia opossum, with a gestation period of about 12-13 days, though some marsupials like the stripe-faced dunnart (11 days) and short-nosed bandicoot (12 days) also have incredibly short pregnancies, giving birth to tiny, underdeveloped young that mature in a pouch. 

Has a human ever mated with an animal?

No, a human has never successfully mated with an animal to produce viable offspring, as genetic differences, especially chromosome count (humans have 46, apes 48), make true biological hybrids impossible, though historical scientific attempts failed and myths persist. While some scientists tried to create human-chimp hybrids (humanzees) in the 1920s, they failed to achieve pregnancy, and modern lab efforts focus on chimeras (mixing cells in embryos) for organ research, not reproduction. 

Do lions engage in homosexuality?

Yes, lions, both male and female, engage in same-sex behavior, including affectionate bonding and mounting, though it's debated whether this is purely sexual or serves social functions like strengthening male coalitions, with estimates suggesting male-male mounting occurs in about 8% of cases. Male pairs often form strong "bromances" for territorial defense, while female pairings are common in captivity, sometimes linked to high testosterone or social dynamics, rather than exclusive homosexual orientation.
 

What is a lion's worst enemy?

A lion's worst enemy is arguably humans, due to habitat loss and hunting, but their fiercest natural rival is the spotted hyena, with packs capable of killing cubs or even weakened adults, while other threats include buffalo, elephants, and crocodiles, especially near water.
