Although the Uros Indians of the floating islands have intermarried with Aymara Indians and no pure-blooded Uros exist, many of the inhabitants of the islands still practice the old traditions of fishing, trapping birds and living on the lake plants. The totora reeds which grow abundantly in the shallows of Lake Titicaca are used for their boats, houses and to build the very islands on which they live. The result is a strange springy surface which requires care when walking - it's easy to put your foot straight through! This strange way of life began over 500 years ago when the Uros built the islands in an effort to isolate themselves from the Collas and the Incas.
The Legend say that the Uro Indians had black blood that helped them survive the frigid nights on the water and safeguarded them from drowning.
the Uros islands, are a group of 42 or so made of floating reeds (totora, a reed that abounds in the shallows of the lake). These islands have become a major tourist attraction for Peru, drawing excursions from the lakeside city of Puno. Their original purpose was defensive, and they could be moved if a threat arose. Many of the islands contain watchtowers largely constructed of reeds.
