Apr 10, 2018 by News Staff

In a groundbreaking genetic kinship study, a research team led by the Florida Atlantic University’s Harbor Branch Oceanographic Institute is the first to reveal that just like human societies, beluga whales (Delphinapterus leucas) appear to value culture and their ancestral roots and family ties. The researchers have demonstrated that related whales returned to the same locations year after year, and decade after decade. Not only do these whales...
