Dragon's Blood trees, known locally as Dam al-Akhawain, or blood of the two brothers, are seen on Socotra island March 27, 2008. Prized for its red medicinal sap, the Dragon's Blood is the most striking of 900 plant species on the Socotra islands in the Arabian Sea, 380 km (238 miles) south of mainland Yemen and 80 km west of the Horn of Africa. Socotra islands, which harbour many unique species of birds and plants, may gain UNESCO recognition in July as a world natural heritage site. Picture taken on March 27, 2008.
