One of the strangest meal-times in the animal kingdom has been caught on film by a BBC crew. The team recorded footage of a female worm-like amphibian, called a caecilian, allowing her young to peel off and eat her skin. Scientists have only recently discovered this bizarre parental behaviour. The female caecilian's skin becomes thicker and more nutrient-rich when she bears offspring. And the young have specialised teeth for tearing and removing it. The crew was able to catch this b

First Lungless Frog Found The first recorded species of frog that breathes without lungs has been found in a clear, cold-water stream on the island of Borneo in Indonesia.

I learned at a tender age not to take candy from strangers. Why would I take a drink from a stranger? Especially considering how numerous people I've met in this city have had experience with doped drinks? So if you meet a girl you've never seen before at a bar and think she's the cat's pyjamas, don't go buy a drink and bring it to her. Don't insist she drink it. If you really want to get her a drink, order it in front of her when she's at the bar, where she can see nothing was slipped into it.
