Marine Mammal Behavioral Study
One of my future goals is to deepen my knowledge on pinnipeds and their behaviors. I have had the incredible opportunity of taking Marine Mammals of the Salish Sea at Friday Harbor Labs where I got to observe pinnipeds in their natural habitat. Additionally, upcoming summer I will be interning at New England Aquarium where I will be working with 2 different species of pinnipeds. This made me wonder what are captive pinnipeds most common behaviors and how does pinniped behavior in captivity differ from pinniped activity in the wild?
With this question, I made a potential research project I will complete this summer to analyze the behavioral differences between captive and wild pinnipeds. I will begin by studying the captive seals and sea lions for a week during my internship via ethogram to understand their behaviors. I will then analyze and summarize my field notes on pinnipeds from my Marine Mammals of the Salish Sea class. Lastly, I will compare and contrast the behavioral findings in my intern presentation at New England Aquarium.
Steller sea lions I saw hauled out on Spiden Island, WA in spring 2026.
Harbor seal I saw off of Friday Harbor Labs campus, spring 2026.
I would expect there to be large differences between the behaviors of captive versus wild pinnipeds, specifically in feeding behaviors and reactions to human interactions. I think that the captive pinnipeds would be much more docile in terms of feeding and when faced with human interaction. They are hand fed by humans, leading them to not exhibiting as strong of hunting behavior as a wild pinniped. Additionally, aquariums are for the public so the seal in captivity interacts with both the marine mammal trainers and the general public every single day making them much less scared of humans than wild pinnipeds, causing them to have a major difference in behavioral reactions to human interactions.
After I get the results of this study I would like to further my work with this project and dive deeper into the ethics of captive animals. All of the pinnipeds at New England Aquarium are rescues but many institutions do not have rescue animals. I was inspired by Peter Singer and Temple Grandin's work in animal ethics and I would love to dive deeper into the ethics of captive animals after comparing the behavioral differences between them and the wild populations.
