EAAM members invest significant resources in funding or conducting important scientific research. EAAM members also cooperate with outside researchers, providing free access to their facilities and animals for well-designed studies. Much of the research underway today is possible only in the controlled environment of zoological parks. Knowledge gained from scientific study of marine mammals in human care directly contributes to the knowledge and conservation of marine mammals in the wild. For example, baseline data obtained from testing at EAAM parks helps with the diagnosis and rehabilitation of stranded animals, saving lives. Studies on auditory capabilities and vocalisation patterns and learning can help to better understand how cetaceans communicate in the wild. EAAM members also fund and/or participate in projects aimed at species and/or habitat conservation.
