It is unlikely that a new kind of young milk was given milk, researchers said on Friday. It has sugar, fatty tissue and about four times more protein than cow's milk.
Although lactation and care is usually associated with mammals, some other animals – like these jumping spiders – do the same.
A new study released on Friday in Science, reveals invertebrates, Toxeus magnus also produces milk for feeding young people.
Researchers at the Chinese Academy of Sciences made a discovery while tracking the observation of Toxeus magnus – an antigens who had jumped.
Spiders are usually lonely, but scientists have noticed that the group was thrown into the nest. This includes groups of one adult woman and several young people.
Researchers have also noticed that baby spit has grown steadily even though they have never left their nest. There was nothing suggesting that their mothers bring food.During recording of the growing spider size of one night, Principal Investigator Zhanqi Chen noticed some spiderlings attached to his mother's body.
"I had many hypotheses, but this was not involved," Chen said Scientist, "At that moment I was so excited, I could not sleep."
It seemed to him that the spiderlings were holding the mother's breast – just like the mammals.
The group learned that mothers secreted the dairy substance from their epigastric strains, the abdominal ears from which they lay eggs.
Researchers have argued that if the loose definition of milk is a nutrient that is nutritious, then it is considered milk.
Researchers have managed to get a spider, under a microscope, to drain a few drops of milk "after light finger pressure on the abdomen," Chen said.The secretion "really looked like mammalian milk," co-author of study Rui-Chang Quan said.
They analyzed the fluid and discovered that they had sugar, fatty tissue and about four times more protein than cow's milk.
Scientists have previously learned that some non-mammal beings also make milk to feed their youth.
Helmets, for example, feed their developed embryos with milk protein rich in fluid.

It is known that other non-mammals feed their young substances that their bodies produce. Balls and pigeons, for example, produce "milk for crops" which parents are re-growing for their youth.
Here's what they've learned yet.
Without access to mother's milk, Tooseus magnus spiderlings dies in the first 10 days of life.
During the first three weeks after leaving their eggs, raisins were fed exclusively on mother's milk.
Many continued to consume milk after leaving the nest. According to Chen, this prolonged period of lactation is more similar to the process commonly observed in mammals than in cockroaches (who only use their embryo feeding milk).
Researchers have a few remaining questions that they hope to face in future experiments.
They want to investigate if spiders, like mammals, produce milk in dairy glands.
Of the 50,000 species of spiders, it is likely that Toxeus magnus is not the only one that produces milk for the feeding of young people.
