An okapi gives birth in a normal way to a single offspring at a time. The gestation period is up to 16 months after which it will find a dense vegetation area to give birth.
It is the average interval of time between the birth of parents and the birth of their offspring,
Sheep and goat are 2 examples of farm animals that give birth to more than 1 baby at a time
An eleven multiple birth is referred to as an "undecuplet." This term is used to describe a situation where a woman gives birth to eleven offspring at one time. Such occurrences are extremely rare and typically involve significant medical challenges for both the mother and the babies.
The gestation period of the animal is the time it takes between conception and giving birth. The length of time this takes can have great variety between the species but is usually associated with the size of the animal.
Marsupials are mammals with a pouch. A female marsupial gives birth to a very tiny baby, which climbs into a pouch on its mother's belly. Then the baby nurses and continues to grow until it's large enough it doesn't need the pouch for protection.
Life span is one life time. Life cycle is from the animal to its offspring to their offspring etc. Butterflies, for example: egg -> caterpillar -> chrysalis -> butterfly -> egg etc
Taking care of offspring is a time and energy consuming undertaking. If an animal produces many offspring there is little need to care for them all.
The carrying of live young inside a female animal that gives live birth is called gestation. The length of the time spent in the gestation of one baby or one litter of young is called the gestation period. The time that a baby spends inside its mother (if its mother gives live birth) is called the gestational age.
