An adult humpback whale measuring between 10 and 12 metres (33 and 39 feet) in length has been spotted near Slovenia's Adriatic coast, a Slovenian Internet news site reported Monday.
"It is a humpback whale, a species that rarely enters the Adriatic Sea and has only been spotted six or seven times in the Mediterranean," Slovenian marine mammal researcher Tilen Genov told the news website 24ur. "This is a very rare event," he added.
The animal, an adult "Megaptera novaeangliae," may have been stranded in the Adriatic Sea due to illness or after following a school of fish, Genov said.
The whale was spotted for the first time by a Slovenian diver on Saturday and then again on Monday in the area between the port of Koper and the coastal town of Izola.
