I'm not going to spew bullshit here that I know much about the many different tribal groups that inhabit the top end of Australia, the place where I live, but I'm lucky enough to have had a few brief tastes of the aboriginal culture and those experiences exposed the beauty of the people and their profound relationship with their environment.
Walking through thick mangroves with a long metal wire looking for mud crabs is about the extent of my practical knowledge of traditional hunting, but I am well aware of the presence of the long, flaccid globs of snot that are referred to as mangrove worms.
I have no idea of their nutritional value, but I'm guessing, being a mollusc, they're probably fairly high in zinc, copper, vitamin D, selenium and iron. Why else you would put them in your mouth on purpose, I have no idea.
My bullshit out of the way, if you're looking for something other than cute cats to make you smile today, watch this and then look for the other videos online.
