Ecology
Caspian seals (Pusa caspica) and a number of different marine birds are common on the shores of this long island. Gazelles (jeirans) are also to be found on Ogurja Island. The gazelles are not endemic to the island, but were settled there as part of a natural reserve project during Soviet times when Turkmenistan was part of the USSR. Ogurja Ada is now part of the Hazar Nature Reserve of Turkmenistan.
