The Pelagos Cetacean Research Institute captured amazing footage of sperm whales in the Ionian Sea.
These images are recorded for the first time in the Mediterranean Basin.
Pelagos has been studying these whales across the Greek Trench – from Kefalonia to southern Crete and Rhodes- for the last 25 years and knows most of them one by one.
Mediterranean sperm whales, which can reach 20 meters in length in the oceans and 15-16 meters in the Mediterranean Sea, have been on the endangered species list since 2006.
Only about 200 live throughout the Eastern Mediterranean.
Most of them live along the Greek trench which has been recognised as an Important Marine Mammal Area – an area of global importance for cetaceans.
