Just turn your back, Mom

A female in a species of legless amphibians called caecilians nourishes her youngsters by letting them eat the skin off her back, says an international research team.

Caecilians, which look like worms or snakes, burrow through the soil in the tropics. Some species lay eggs, and quirks of several of these species got Mark Wilkinson of the Natural History Museum in London and other researchers wondering whether these moms fed their young. The hatchlings had scraperlike teeth, for example, and they hung around their mother for their first weeks of life.

Now studying the egg-laying African species Boulengerula taitanus, Wilkinson and his colleagues have found the missing baby food. They dug up and observed 21 nesting females and their broods.
