In the Sea of Japan there is a vast, but shallow, Peter the Great Bay. It is located on the border of two natural zones: temperate and subtropical. This explains the incredible diversity of living creatures living in its waters.
In 1978 To preserve the natural resources of the Peter the Great Gulf, the Far Eastern Marine Reserve was created. It consists of four sections, each of which is unique in its own way.
The largest is the Eastern section. It includes the Rimsky-Korsakov Archipelago. Big Pelis Island is the largest of the islands in the archipelago. Here from late autumn to the end of spring you can meet the spotted seal - larga.
The southern section of the reserve is located fifty kilometers from Bolshoi Pelis Island.
There is only one island here - Furugelm Island.
This is the southernmost island not only of Primorye, but also of Russia. Furugelma Island is home to the world's largest colony of black-tailed gulls. There are about fifty thousand of them here.
