Fancy a cup of milk? Baby spiders suckle ‘spider milk’ from their mothers
The fluid contains nearly four times the amount of protein found in cow’s milk, and appears to be sufficient to nourish the spiderlings until they reach maturity. In their study, published in Science, the team observed as the mother left drops of the milk around the nests for their offspring to find, before they graduated to directly sucking from her body. Although nursing was not critical to the spiderlings' survival after becoming independent, access to their mother's milk improved their overall health and adult survival.
