KRASNODAR, December 23. /TASS/. Environmentalists have discovered eight more dead dolphins along the Krasnodar Region's coastline following an oil spill caused by a tanker crash, Director of the Scientific-Ecological Center for Dolphin Rescue called Delpha Tatyana Beley told TASS.

"Four [dead dolphins were found on the beach] in Aleksino, three more [on the beach] Volochaevsky and one on the Sudzhuk Spit. These are the minimum numbers," the agency source said. She specified that these were new cases of dolphin deaths after the accident in Novorossiysk.
