Authorities previously reported the death of nearly 300 endangered seals on Dagestan's Caspian shore in December 2020.
"These are the dead animals that we saw, photographed and whose GPS coordinates we noted," Viktor Nikiforov of the Moscow Marine Mammals research centre told the AFP news agency on Thursday.
Images shared with the AFP showed several seal carcasses washed up on the beach.
The deaths may have been caused by "industrial pollution, fishing or poaching when seals get caught in the nets", Nikiforov said.
