1001 strange reproduction patterns of animals

The animal world always contains interesting things, challenging human understanding. Let's review some animals that have a very strange reproduction process to see the abundance of nature.

Animals that give birth in a strange way

1. Elephant

The gestation period of the elephant is up to 23 months, the longest of all the terrestrial animals. More specifically, a newly born baby elephant weighs about 120kg.

2. Frilled shark

The difference in this eel-shaped shark is the very slow development of the embryo, which is only about 1.4cm per month. With such a speed of 'crawling', pregnancy in the sharks lasts for 3.5 years.

3. The opossum marsupial

14 days is a relatively easy gestation period for opossum marsupials. In addition, the calf will be nourished within the mother's bag for 2 to 3 months.

4. Seahorses

If there is a title for 'special fathers' then the male seahorse will surely win. Seahorses give birth in a strange way: males play a role in pregnancy and hatching eggs. The female lays eggs in the bag in front of the male belly. The egg is then fertilized. When baby seahorses hatch, they remain in the incubator and swim outside as adults.

5. Dog

24 - that is the number of puppies born in a litter at the most so far. The Guinness Book of Records recognizes that achievement of a British mother named Tia in 2004. After this spectacular "crossing", 20 children survived.

6. Guinea pig

Being the champion in breeding, hamsters are able to get pregnant very early, when only 4 weeks old and take 2 to 15 hours after birth can regain all their energy.

7. Octopus

Octopus is an egg-laying species. They have a very strange reproduction process. When sexual intercourse, males use tassels (often called 'copiers') to bring sperm into females. Female octopus can hold sperm in humans until eggs are ready to fertilize (an average of 200,000 eggs). The mother will then protect and supply oxygen to the eggs by blowing water over.

8. Dolphins

Near the birth date, the mother's dolphin body increased by 50% compared to normal. The gestation period of dolphins is usually long, about 1 year.

9. Tatu

Like some other mammals such as bears and badgers, tatu has the ability to delay and keep an embryo in a state of "dormancy", which is inactive until it is conducive to pregnancy. Although the gestation period only takes about 4 months, but because of the delay, it should take 8 months after mating, the new calves are born.

10. Chimp

Chimpanzees are the closest relative of humans among animals, so it is no surprise that they have a breeding process quite similar to humans, from mating and pregnancy to childbirth.

11. Fish eat raw meat hatching eggs in the mouth

This fish lives in the waters off Malaysia. After the egg is fertilized, the male will suck the eggs into his mouth to protect the unborn children from the enemy. Males take part in oral incubation for weeks. During the incubation period, the male fish must even fast completely until the eggs hatch into fry.

Although male fish do not eat during incubation, some scientific studies have found that up to 30% of eggs float into the male's abdomen. This is why this fish is called carnivorous fish.

12. The male male Darwin gave birth to a baby by mouth

This frog still lays eggs as normal, the male will then swallow their eggs into the abdomen, incubate the eggs in the stomach for at least 6 weeks, the eggs will hatch into tadpoles. After that, the male will vomit them through his mouth. When the frog swallows eggs into its stomach, its stomach will temporarily stop secreting acid so that the eggs are not destroyed like food. The time of hatching them does not go out to feed.

Surinam Toad eggs hatched and gave birth to their babies

This toad is also known as the beehive toad, which lives mainly in the water in the South American region, with small holes like honeycomb holes on the back.

By mating season, eggs will be fertilized outside and then spread to the back of fertilized eggs. Eggs will get into the honeycomb holes. Here the eggs develop into tadpoles, when the toad-shed tadpoles will come out of their mothers' backs.

14. Hammerhead sharks reproduce monotonously

Female hammer sharks can reproduce without male fish. A female shark is very difficult to find a male because in the vast ocean their numbers are decreasing so the reproductive phenomenon is likely to occur much.

15. Egg platypus

The shape of the platypus is very special, its mouth is like a duck's mouth, its tail is like a fish's tail and its legs are like frog legs. What amazes people is that platypus are mammals but they lay eggs instead of laying off babies.

Once a platypus can produce 1- 3 eggs. Eggs over 10 days of incubation will open. Child of newly hatched platypus 2.5 cm long. The female has no breast, the milk from the abdomen flows out. When you give your baby milk, the ducklings will lie on their stomachs to the sky. The platypus climbs up on its mother to lick the food, which is a different point of platypus.
