What animal gets pregnant the fastest?

The length of gestation varies from species to species. The shortest known gestation is that of the Virginian opossum, about 12 days, and the longest that of the Indian elephant, about 22 months. In the course of evolution the duration of gestation has become adapted to the needs of the species.

Which animal has 25,000 teeth?

What is the shortest pregnancy in humans?

James Elgin Gill was born in Ottawa, Ontario, on May 20, 1987, around 128 days early or 21 weeks gestation. He set a record when he was born for the world's most premature baby. 20 James was born so early that he was expected to die at birth or—if he survived—to have multiple and severe handicaps.

Roughgarden posits that while animals come in only two sexes, many species have more than two genders. How can this be? Sex refers to the size of the gametes, and, quibbling exceptions aside, sexually reproducing species have only two types of gamete, big and small (eggs and sperm).

Can sharks change gender?

Other scientists believe that the big sharks, like some other species, change sex when they reach a certain size: males become females. The switch may ensure survival by allowing the largest, most experienced sharks to give birth to young.

What animal has the dad give birth?

Seahorse fathers break all the rules—they're the onces who get pregnant and give birth.
