Biologically, its proven that mammals give milk to feed their young babies, but with the recent study of the scientist discovered that other than mammals, the spider can also produce milk and feed its young ones. The mother spider nearly feeds their offspring for 40 days.

The previous studies on spider say, “Spiders don’t eat anything until they grow in size these but these spiders grow in size very faster. They grow half to their adult size during the first 20 days itself.”


Zhanqi Chen at the Chinese Academy of Science said, “We couldn’t figure out how they just keep growing without food until one night, I saw a baby spider clinging onto its mom’s belly.”

Eventually, researcher Zhanqi Chen analyzed something very surprising. The young spiderlings crowding around the mother’s abdomen, drinking a white fluid coming from the reproductive organ used to produce eggs.

To check whether drinking this “milk” truly affected the survival of the little spiders, Chen along his collaborators ran a number of tests. They put white-out paints across the area of the mother spiders’ abdomens where the milk flowed from, blocking its secretion. and surprisingly all the baby spiders stopped developing, suggesting total dependence on the milk supply in their early days, the researchers have written in their papers. In follow up studies, the scientists found that the milk was essential for the first 20 days of life only and afterward the young spiders started to fend for themselves. But they still drank the milk every so often and the continued maternal care greatly boosted their ability to survive and live.

Reported by the New Scientist, “I had this radical idea that maybe spider moms feed their babies with something they produced.” While comparing the milk with cow milk, that is drunk by human beings apart from its young ones, spider milk seems to be having the same use as mammalian milk that is nourishment of the young ones.
