Spider milk

Today I learned that there are spiders that produce “milk”. While “milking spiders” is usually talking about collecting poison to create anti-dotes, this milk from spiders is used to raise their children, “spiderlings”, from offspring to a “mature” age. The little spiders lap up those little “milk” droplets from the underside of the spider mother. There is the theory those milk droplets may have evolved from “unfertilised eggs”.

I came across that during an casual talk1 with someone mentioning spider milk and I was curious and came across this article by the independent, which leads to this research paper.
