1, flatworm australis
Australian flatworm, an invertebrate of Platyhelminthes, is hermaphroditic. When mating, whoever inserts his genitals first plays the role of male.
In addition, flatworms all over the world are mostly hermaphroditic, often self-fertilized, but also cross-fertilized. There are also asexual reproduction.
2. slugs
During mating, the slug secretes mucus from the tail, forms silk, sticks to the branches, and the body hangs upside down in mid-air, next to each other, and then the reproductive organs protrude from the jaw, white, translucent, banded and soft, which are basically the same length as the body, and the top of the organs are connected, and then spirally wound, but not twisted straight together, but have a "flattening" effect, so it looks like it at last.
3, eel
Monopterus albus belongs to Fishes, Syngnathidae, Syngnathidae, Monopterus albus; Ordinary freshwater edible fish, without scales, can erect the first half of the body in shallow water, breathe through the mouth to the surface of the water, and store air in the mouth and throat, so it appears that the throat is swollen.
Widely distributed in southeast Asia, it is found everywhere except the northwest plateau, inhabiting ponds, rivers, rice fields and other places, often lurking in mud holes or crevices, and foraging at night.
Monopterus albus is not a hermaphrodite creature, and its reproductive situation is special. It is female when it is young, and then it turns into male after one reproduction. This phenomenon of female-male transformation is called sexual reversal.
4. Parasitic bees
Small parasitic bees are usually called "hermaphroditic", that is, the male and female chromosomes in their bodies are mixed together in disorder. Their behavior undoubtedly shows that their most important sexual organ is the "brain".
However, some parasitic bees have a male brain and a female body-this is the "hermaphrodite", and then their mating behavior will be disordered: it will sting the female bee and try to mate with the moth larvae. It will even fool around the female bee without mating with it; Or suddenly stop at the beginning of mating, as if remembering something important.
5. Sea bass
Sea bass is a kind of delicious fish, and it has also undergone a complete denaturation process-from mature female to mature male. This denaturation process is usually carried out when the sea bass is 5 years old. There is a subspecies of sea bass called "banded sand fish", which is abundant in Florida waters. This kind of fish can self-fertilize.
