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.”

This pretty spider is Toxeus magnus from the famous family of jumping spiders Salticidae. Besides being similar to an ant, this week these little spiders became famous, since a very interesting paper has been published in Science journal. In this paper our colleague Zhanqi Chen tells us how females of this species feed their offsprings, and it was quite surprising for us that it produces milk to feed them! Yes! This is what mammals do, right? But now we know spiders also secrete milk! The milk of spiders and its proteins also opens a new biotechnological window for researchers to explore! …… …… Esta linda aranha é Toxeus magnus, da família das aranhas saltadoras Salticidae (conhecidas como papa-moscas aqui no Brasil). Além de ser parecida com uma formiga, esta semana essa linda aranha ficou famosa nos jornais, revistas e redes sociais, pois uma publicação na revista científica Science, de autoria do nosso colega Zhanqi Chen, mudou bastante a forma como nós olharemos para a biologia e evolução de aranhas daqui pra frente. Neste trabalho ele demonstrou que Toxeus magnus amamentam seus filhotes com um leite produzido pelas fêmeas. É isso mesmo que você leu. Mas não eram os mamíferos que produziam leite para alimentar filhotes? Sim! Mas agora sabemos que aranhas também! O leite da aranha e suas proteínas também abrem uma nova e importante janela para as pesquisas biotecnológicas. #womaninstem #womeninscience #womeninstem #womaninscience #spider #spiders #arachnids #science #invertebrates #zoology #biotechnology #spidermilk #spiderbehavior #naturalhistory #biology #salticidae #jumpingspider #papamoscas #zoologia #aranhas #aranha #aracnídeos #arachnida #araneae #mulhernaciencia #mulheresnaciencia #mulhernaciência #mulheresnaciência #leitedearanha #aranhassaltadoras
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.

Spiders! They're just like us…⠀⠀⠀⠀⠀⠀⠀⠀⠀ .⠀⠀⠀⠀⠀⠀⠀⠀⠀ Well, ok, not really, but mammal-like milk provisioning and parental care have just been discovered in a certain type of spider!⠀⠀⠀⠀⠀⠀⠀⠀⠀ .⠀⠀⠀⠀⠀⠀⠀⠀⠀ In other words, Spider Milk Is Real and Their Babies Love It! Check out the articles today in Gizmodo, National Geographic and Science Magazine.⠀⠀⠀⠀⠀⠀⠀⠀⠀ .⠀⠀⠀⠀⠀⠀⠀⠀⠀ .⠀⠀⠀⠀⠀⠀⠀⠀⠀ .⠀⠀⠀⠀⠀⠀⠀⠀⠀ #breastfeedinstyle #spidermilk #science #lovecommamama
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.
