Top 10 unusual ways of animal reproduction


Our world is truly unique, like every individual of his creation. Observing animal behavior, scientists are not tired to be surprised to unusual habits. Someone who cares about the offspring is better than modern people. Others feed on distinctive methods, travelling on other types of animals. Others show sexual tendencies.

On the subject of mating of animals released many different scientific films and videos. About the female praying mantis, otkazyvayus head to his partner during coitus, we heard time and again, and I want something new, so to say "fresh facts".

We present you the latest collection of fauna that reproduce the unique, and sometimes shocking way.

10. Slug

These slippery spineless creation by nature are hermaphrodites, that is, combine in one body of the female and the male reproductive system. But for laying eggs, it is still necessary cross-fertilization, so members of the species by smell are looking for a mate, realize short "mating dance" and exchange sperm. After that, the female body start the process, so each of the participants of mating can lay eggs – an average of 2-3 dozen. Sexual activity of these animals is striking – after a month of life after active "gain fat" young slug is ready to breed.

9. Rhinoderma Darwin

Mating in frogs occurs in the standard way, but the process of "birth" with unique features. Fertilized eggs swallowed by the male rhinoderma and contains a voice (sound) the bag that makes life difficult for the amphibians do and the process of supply. Dad carries the eggs to complete maturation and hatching of tadpoles, which prevents their premature loss eating predatory animals. The grown young animals, the male releases out. That's such an unusual concern and sacrifice on the part of the father.

8. Cuttlefish

This colorful mollusk is long known for its ability to masquerade as the environment. At the same time to cycle through colors it can in a split second that allows you to quickly hide from enemies and, of course, to win the vending lady. This skill is required, because males in nature are much more (sometimes the number exceeds 10 times), forcing the latter to fight for the right to mate. And in this battle, interestingly, often wins, "intelligence", not Brawn. That is more weak and small cuttlefish can get the "lady", only correctly applying the skill of disguise. And becomes the male...female! While this is clearly hides the additional tentacle to distribute the sperm, and simulates the presence of a special pouch for carrying eggs. "Transvestite" quickly blends in and flows freely to the female.

7. Chickens

It would seem that poultry little to surprise us – already investigated numerous times. But really no one wonder how chickens reproduce. It turns out that if in the pen for a long time no cock, females can rebuild their reproductive system and reproduce independently in the usual way. Of course, this situation is rare, but is the place to be.

6. Deep-sea anglerfish

Monkfish always gets into different tank Tops as one of the most horrific or unusual fish. But different he has managed in the method of reproduction. It turns out that the anglers are adherents of "sadomasochism". After reaching sexual maturity the male with all the passion bites in a female body, which, incidentally, can be several times larger. Eventually there is a coalescence of bodily membranes and circulatory system, and the male, in fact, plays the role of a reservoir for semen, fed by the females. It doesn't already own fins and even the eyes. But that's not all. The female sadist is able thus to destroy and to carry up to six males. Yes, and regulates the time when the eggs must be fertilized from the "sperm Bank".

5. Tiger sharks

Beautiful and terrible sharks, like many other marine animals (not fish), the practice of live birth. It's not the eggs, larvae, and even young fish, and complete a small copy of an adult shark. Bloodlust marine predator appears from the first months of life, because the threat the cubs immediately rush packs to use own sisters and brothers. In the end, in a vicious battle and only the strongest survive and healthy.

4. The octopus-YouTube

This sea dweller is also a regular at various Tops and reviews. Today we will tell you more about the sad moments of his sex life. Males of this species are forced to suffer from sexual hunger, because nature gave them a very unusual type of penis. After self-sperm production reproductive organ separated from the body and goes to free swimming, in the hope of finding ready to breed female. Here's a floating "sperm Bank", which may stumble in the depths of the sea, any wishing to have offspring. The male could only sadly watch as his ex part of the body alone mate with a partner. But that's not all. Penis, it turns out, eventually grows back, preparing the male to the new act at a distance.

3. Seahorse

Playful and lovely creatures inspire scientists for various studies. The males of this species are not particularly lucky in his personal life, because they have it all wrong. At the beginning everything seems like others have had several long visits, intimate dance with linked tails and graceful movements. Then the Mature female of the implant in the body of the male eggs that unite with sperm and begin to ripen in a special bag. That is "pregnant" turns out it is the horse male. Grief the father must bear on yourself up to two hundred small copies! After "birth" the male is leaving the offspring, giving them his own way in life.

2. Kangaroo

About the unusual reproduction of kangaroos know even small children. Marsupial surprises with its "open" to pregnancy, because the embryo can be seen without special ultrasound machines and other devices. Preterm baby after birth the female body alone crawls into the bag, where it awaits a nutritious mother's milk. There are formed the organs of the kangaroo and his limbs. It's funny to watch a grown and independent child kangaroo is still sitting comfortably in the sagging bag, an unhappy mother and meets a world – well pure parasitism!

1. Histoplasma lizard

The females of these reptiles are so independent that the males to them for mating is not necessary. The process of reproduction they have is called parthenogenesis, that is, occurs without fertilization of the egg. The lizard is essentially a hybrid mixture of offspring from 2 different species: the Western and the Arizona striped christodolou. Such hybridization leads to unhealthy offspring males and degeneration. By the way, the lizard is able to set aside over the summer to 4 unfertilized eggs, from which in a few months hatch into young females.

The nature of the fauna is incomprehensible and again and again surprises the world community of scientists. And we can only wonder what tricks and animals ready for play own.
