The Ministry of Natural Resources of the Russian republic of Dagestan has reported that 2,500 dead seals have been found on the shores of the Caspian Sea.
«The carcasses are in different places,» the Ministry has explained in a message posted on Telegram. The highest concentration is in the Yuzbash area and between the mouths of the Sulak and Shurinka rivers.
The bodies are already being examined to determine the cause of death by studying pathological material, the Russian news agency Interfax reports.
On Saturday, 650-700 dead seals were found in the Kirovsky district of Makhachkala, Dagestan, between a fuel depot and the mouth of the Sulak River.
So far, examination of the seals’ internal organs does not support hypotheses pointing to heavy metal or pesticide poisoning.
