Some kind of Orb-weaver spider I think.

🕷️ A jumping spider that nurses its young with milk — 4x the protein of cow's milk
Female Toxeus magnus spiders secrete a milk-like fluid from their egg-laying opening for nearly 40 days after hatching. Newborns drink nothing else for the first 20 days and die within 11 days if the mother's milk supply is blocked.
Even after spiderlings learn to hunt at day 20, they keep nursing alongside their own kills for another three weeks. Daughters are allowed to return to the nest after reaching adulthood, but adult sons are attacked if they try.
This subverts the long-held assumption that lactation and extended milk-provisioning are exclusive to mammals.
