How do hyenas give birth?
Female hyenas have three times more testosterone than males, which results in a peculiar and risky labor process. Female hyenas give birth through their clitoris, also called a pseudo-penis. The birth canal of a hyena is only about one inch across, and consequently, many hyena babies do not survive.
How do seahorses have babies?
After an elaborate courtship “dance,” females deposit their eggs into a male’s brood pouch, where he fertilizes them. As the embryos grow, the male’s abdomen becomes distended, just as in a human pregnancy. When he is ready to give birth, the abdomen opens, and contractions expel the juvenile seahorses.
Who has the shortest pregnancy?
the Virginian opossum
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.

How do you light a Surinam toad aquarium?
As with most amphibians, the most essential part of lighting the Surinam toad’s aquarium is that you provide a day and night cycle. You can easily rig a basic fluorescent aquarium tube to a timer to ensure that the toads have 12 hours of light and 12 hours of darkness every day. Most frogs, and aquatic ones in particular, have very sensitive skin.
