This varies widely depending upon the species and the individual. I'll give three examples: humans, cows and horses.
From the water breaking to the placenta being discharged, some human females can take as little as 2 hours while other females are in labor for 2 days.
In cattle, from the water breaking to the placenta being discharged, some cows can clear the calf and placenta in 3 hours, while other cows may retain the placenta for 4 days.
In horses, from the water breaking to the placenta being discharged, a mare needs to get everything done within about 6 hours or she is in a life-threatening medical emergency.
the leopards are to small and very intelligent
Yes, animals will give birth to their young even if there is a chance of dying. These are some risks that animals will take to further their population.
No, not all animals give birth to live babies. Some animals, like reptiles and birds, lay eggs and the babies hatch from them. This method of reproduction is called oviparous.
All fish lay eggs. There are some water animals that are mammals like the whale and porpoise. They give birth.
Yes, a whale is a mammal and gives birth do live babies.
All animals give birth alive: it would be difficult to give birth when dead, at least using the commonly understood meaning of "give birth". Of course, some creatures (e.g. caterpillars used as hosts by parasitic wasps that lay their eggs inside the live animal) are dead (or die) when the wasp larvae emerge, but that's not really "giving birth".
Oviparous animals lay eggs that hatch outside of the mother's body, while viviparous animals give birth to live young that develop inside the mother's body. Oviparous animals include birds, reptiles, and most fish, while viviparous animals include mammals and some reptiles.
All animals are born alive but some lay eggs while others give live birth. Animals that give live birth include all mammals except the monotremes, a few species of fish, a few species of snake and even a few species of insect.
Mammals are some of the animals that give birth to live young ones. Mammals are warm blooded and mostly live on land.
There are no whales that give birth to dolphins. Dolphins give birth to dolphins; whales give birth to whales.
Most mammals the exceptions being the platypus and the echidna.Also there are certain species of almost every group that has some member performing live births. Some that I know of are: spiny dogfish, aphids, velvet worms, red slider snake, Madagascar Tree Frog...mammals like us. But not Birds, some reptiles, and others!Mammals.
Viviparous animals give birth to live young from within the body rather than laying eggs. Example sentence : Nearly all mammals and some reptiles are viviparous animals.
