The director of the Persian Gulf Martyrs Lake Recreation and Tourism Complex (Chitgar) has claimed that it was completely clear that there was no crocodile in Chitgar Lake and that the creature seen was a fish duck.
Razavikia further stated: The place of the claws around the lake was also related to some dogs. So the search for a crocodile in the lake is over. Lake aquatic species are being reconsidered and fish and organisms that are dangerous and harmful to the lake ecology are also being transported.
