Jumping Spiders Nurse Offspring Nearly to Adulthood American Association for the Advancement of Science (AAAS)

Like nursing baby mammals, some jumping spiders spend their earliest days feeding on a nutritious "spider milk," secreted by their mothers. What's more, spider mothers continue to care for and feed their young offspring the milk-like fluid - which contains nearly four times the protein of cow's milk -long after they're able to forage for food on their own.
