Summer social distribution of sperm whales ( Physeter macrocephalus ) in the Mediterranean Sea
Sperm whale social distribution was investigated in the Mediterranean Sea, using data collected during summer surveys from 1997 to 2002. Variations in the size of sperm whale schools/underwater aggregations were assessed using both visual and acoustic data. Individual body lengths were estimated aco...
