Via one of our favorite video blogs, The Kids Should See This, check out this incredible video of an echidna—also known as a spiny anteater—hatching from an egg. Echidnas live in Australia and on the island of New Guinea, and they are some of the only egg laying mammals in existence, along with the fantastically weird platypus.
Australia’s Commonwealth Scientific and Industrial Research Organization, or CSIRO, made this video in 1974. On the organization's YouTube page, there are many more examples of wonderfully weird old example of animal videos, including vintage favorites like the echidna hatching or a 1965 educational video about the birth of a red kangaroo. (That last one shows the actual birth of a live kangaroo and is not for the faint of heart.)
