6. Giraffes give birth standing and the baby when it comes out of the womb falls from a height of 5-7 feet from the ground. This serves two purposes. The first one being if a giraffe sits and delivers the baby, chances are that the baby giraffe gets crushed. The second reason is that it helps in cutting the umbilical cord. Though somewhat risky, most baby giraffes manage to make it to the ground.

7. Spiders can actually choose a sperm for fertilization. When a spider mates, the semen of the male spider doesn’t get into the uterus but it goes to a sac like structure where the semen is stored. Because of this, one female spider can mate with a lot of male spiders and leisurely choose the sperm for fertilization. The rest of the semen is simply dumped out. This practice is called “sperm dumping”.

8. Spiders are not the only creatures to use sperm dumping technique but animals like zebra, duck etc. use varied forms of sperm dumping.

9. Mother octopuses die after giving birth to the young ones. During the gestation period, they neither move nor eat, they simply guard their eggs.
