What marine animal has the longest gestation period?

The Sperm Whale (535 days)

With sizes exceeding 60 feet in length and an average weight of 63 tons, the sperm whale is the largest of all toothed whales. The sperm whale also has the longest gestation period of all marine mammals amounting to 525 days after which the female gives birth to a 13-foot newborn calf.

Why gestation period is different in different animals?

Generally, there are two main factors that contribute to the length of the gestation period: Animal size / mass – larger animals tend to have longer gestation periods (as they tend to produce larger offspring) The level of development at birth – more developed infants will typically require a longer gestation period.

Do animals with longer life expectancies have longer gestation periods?

'Animals with longer life expectancies have longer gestation periods.

What animal is only pregnant for 3 months?

As marsupials, opossums give birth to helpless young which they carry inside their pouch for two to three months.

What animal is pregnant for 9?

Elephants have the longest gestation period of all mammals. These gentle giants' pregnancies last for more than a year and a half.

How long are sharks pregnant?

Nursery time

The pups are born after 9-12 months gestation and there can be up to 30 in a litter, although the average is 17. Once delivered, they're on their own, learning to hunt in the shallows for three years or so, before braving the wider ocean.

What determines gestation period in animals?

For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 months).

What is ks2 gestation?

Gestation is the period of development where some animals carry their babies inside their bodies before they give birth.

What was the longest pregnancy?

1. The longest recorded pregnancy was 375 days. According to a 1945 entry in Time Magazine, a woman named Beulah Hunter gave birth in Los Angeles nearly 100 days after the average 280-day pregnancy.

Is there a relationship between the gestation period of an animal and its average lifespan?

An increase in lifespan is associated with an increase in pregnancy length. In other words, animals that live longer tend to have longer pregnancies. The form of the relationship is linear. The relationship is moderately strong.

Why are elephants pregnant for so long?

The scientists hypothesize that the long gestation period allows for full brain development of elephants, which are born with complex cognitive skills and are immediately able to sense how to survive in their environment and interact with the herd.
