body disappears, only leaves the semen and merges into the female body , after mating, "evolves" into hermaphrodite, reproductive organs become two sets of .
Can you imagine what " invert " has become like in order to reproduce in the animal world?
Many animals don’t have to ask for a partner for a long time, and can complete this major life event by yourself .
Who are these "mating gods"? How did they mate with themselves? Does nature allow them to "do things randomly" like this?
NO.1 "Carnival Party" sea slug
sea slug also known as sea rabbit . Although it has two sets of genitals, it is connected by an egg-sperm groove in the middle. But it cannot mate with itself, and must find its kind to complete this "great mission" together. Sea slugs like to revel in a carnival. Every year, a lively "reproductive feast" is held, and groups of sea slugs will gather in the agreed place.
The annual mating season is here, and the sea slugs will form a team on their own to form a super big circle. The two sets of reproductive organs in each have to be used in . No. 1 uses their male genitals to pierce into the female organ of No. 2, and immediately enters the male organ of No. 3. After following a long list of
, the last one mates with the first one. A long circle, connected from beginning to end, the scene is very spectacular, is like a carnival "mating feast" .
Interestingly, during mating, some sea slugs that are impatient and want to end as soon as possible will suddenly lose patience, and bites off the reproductive organs of the same type of mating . But this damage value is almost 0, because these will regenerate quickly. After mating, the other party does not need to take action. sea slugs will discard their genitals like garbage.
The eggs they lay are also long cylindrical like the formation of the party. In order to prevent the small and light eggs from being washed away by the sea water, the sea slug will fix the eggs on the seabed sand and gravel with glue. It is really a matter of effort to mating!
NO.2 "Infused into females" Ankang fish
Ankang fish name sounds like auspicious, but in fact it looks extremely ugly, and you can lose your appetite at a glance. Compared to the sea slugs that like lively, Ankang fish has a skill that other creatures cannot match : after mating, the body disappears, and only a pair of male testicles remain in , which slowly melts into the female body.
When mating, the male fish will bite the female fish's body tightly and enjoy the intimate "posting" for a while. Then part of its head begins to disappear! The organs in the body, fins were also missing, and only the sperm wrapped in the testicles was still developing . After the genus entered the female fish accurately, it was completely integrated. became a part of her body forever and would rely on the female fish's nutritional system for the rest of her life.
Some people are starting to worry. If this continues, will the male Ankang fish die soon? Don't worry, it has a special skill - becoming hermaphrodite. The ethnic group will select a host female fish to receive the semen left by the male fish. As long as the female fish is still alive, it may retrieve sperm from the semen in the body at any time to reproduce.
host female fish can also receive multiple male selves at one time, at most it can reach more than ten. Therefore, every mating, is the end of the life of Ankang fish. is actually tragic!
NO.3 "Male-headed female" parasitic wasp
parasitic is also a hermaphrodite organ. The most important reproductive organ of is actually the head, and its chromosome is also very confusing . They eat plant leaves when they are larvae, and when they are nested and mated, they will eat carnivorously. They are more common parasitic insects.
In the body of parasitic isps, 's gender-determining chromosomes are always intertwined. This also determines that some parasitic bees have very casual appearance. For example, the male shell is equipped with female reproductive organs. When it mating, it will be disordered and suddenly pauses when preparing for the "last blow", as if the computer crashes.
Parasitic bees are also a typical "bird's nest" breeding method. They lay eggs on the surface of the host's body, and allows the larvae to eat nutrients on the surface of the body directly. or lay eggs in the host, allows the larvae to quietly eat the host's body tissue.
NO.4 "Self-produced and sold" flatworm
flatworm is a kind of "freak" with only mouth but no anus. Flatworms are hermaphrodites, regardless of male or female. Before mating, they often decide to mating roles by "drying one fight". Whoever wins is "Dad". The remaining ones who lose will become the "mother" and receive the winner.
When mating, the winning male genitals that will use the pointed and flat male genitals on the tail, directly pierce the other body and shoot the tadpole in. After that, he left swagger, and continued to enjoy the "worm birth" of the single nobles, looking for the next "confidant" .
The "mother" who lost to the game has to take on the responsibility of giving birth and raising larvae by themselves. This is a world where "scumbags are the ruthless".
What should I do when the companion cannot be found to mating?
Mostly, it is allelopathic mating. When you really can't find a partner, you can also complete the "reproduction matter". They will pierce their bodies with dice, and injects tadpoles into their egg cells to complete the "self-produced and self-selling" fertilization process. , however, it will become a father and mother by itself and feed a group of larvae.
NO.5 "Tear open and go straight into" wide-fin eight-handed squid
wide-fin eight-handed squid will emit a special biological cold light. They often adopt a simple and crude way when mating, and the scene is also a bit terrible.
When it comes to mating season, they will use their pointed mouths and claws, to tear a small hole near the female genitals, and then put their sperm pods into the newly torn wound . After the sperm pods circulate through the blood in the female body, they will be integrated to complete fertilization.
Their close relative Nanyang Lixhook squid, will also "dig" in the center of the female's abdomen. After the sperm pod is placed in the female's body, it will automatically secrete a special enzyme, allowing the sperm pod to melt into the body instantly.
NO.6 "Ejaculation Sperm" snail
Our most common snail is also an hermaphrodite creature. However, when snails fire tadpoles, they need their companions to cooperate with each other. They will use their genitals at the same time, repeatedly stimulate the other's reproductive channels, and will also launch an "arrow" composed of calcium salt into the other's body.
When two snails feel the stimulation from each other, they will ejaculate tadpoles at the same time, and enters the other's female genitals . What is beyond reach is that snails usually take more than 2 hours each time they mated, and some can still exceed 4 hours of their "peak period".
I have to say that although snails climb slowly, they really have perseverance in reproduction!
NO.7 "Seamless Switch" Atlantic Flat Shell
Atlantic Flat Shell lives on the coast of North America , and is also an hermaphrodite who likes to mating in groups.
Under normal circumstances, male flat shells like to swim freely at the bottom of the water. When you encounter the female flat shell you like, it will stimulate an instinctive reaction. swims over and lies on their backs and crawls forward until the tadpoles are injected into the female flat shell.
A more amazing scene happened. After mating, the male flat shell will lose its male organs and become hermaphrodite in body structure, and play the role of a female in the next mating. If the new male squid beloved at this time, it will swim above it and mating.
Therefore, Atlantic flat back is not a natural hermaphrodite, but evolved acquired.
It turns out that nature has so many strange androgynous creatures that reproduce in seemingly strange ways to maintain the survival of the family. What else do you know about the weird androgynous mating?
