What is a Marine Mammalogist?

Marine mammalogists are specialized scientists devoted to the study of marine mammals, encompassing whales, dolphins, porpoises, seals, sea lions, manatees, and walruses. They conduct research spanning the biological, behavioral, ecological, conservation, and management aspects of these animals.

Marine mammals often serve as flagship species, meaning their conservation can help protect entire marine environments and biodiversity. The work of marine mammalogists, therefore, is vital for the preservation of marine ecosystems and the sustainable use of marine resources.

Duties and Responsibilities
Marine mammalogists engage in a variety of activities, which commonly include:

  • Field Research – conducting field studies to observe marine mammals in their natural habitats, often involving methods like boat surveys, aerial surveys, tagging, and tracking
  • Data Collection – gathering data on marine mammal behavior, distribution, population dynamics, and health through field observations, photo-identification, acoustic monitoring, and sample collection
  • Laboratory Analysis – analyzing biological samples such as tissue, blood, and feces to assess the health, genetics, and diet of marine mammals, as well as conducting experiments to investigate specific research questions
  • Data Interpretation – interpreting collected data using statistical and analytical techniques to draw conclusions about marine mammal populations, behaviors, and ecological relationships
  • Taxonomy and Systematics – focusing on the classification, evolutionary relationships, and naming of marine mammal species
  • Conservation Efforts – contributing to conservation initiatives by identifying threats to marine mammal populations, developing conservation plans, advocating for protective measures, and collaborating with stakeholders to implement conservation strategies
  • Education and Outreach – sharing research findings with the scientific community, policymakers, and the public through publications, presentations, and outreach activities to raise awareness about marine mammal conservation issues
  • Policy Development – advising government agencies and organizations on policies and regulations related to marine mammal protection and management based on scientific evidence and research findings

Types of Marine Mammalogists
Now that we have a sense of the potential scope of the marine mammalogist’s work, let’s look at some different types of marine mammalogists, each specializing in various aspects of marine mammal research and conservation:

  • Behavioral Ecologists focus on understanding the behavior of marine mammals, including foraging, feeding, breeding, communication, and social interactions.
  • Population Biologists study the demographics and dynamics of marine mammal populations, including abundance, distribution, reproduction rates, and factors influencing population growth or decline.
  • Physiologists investigate the physiological adaptations of marine mammals to their environment, such as diving physiology, thermoregulation, and sensory systems.
  • Conservation Biologists work to conserve marine mammal species and their habitats by assessing threats (habitat degradation, pollution, climate change, and human activities such as fishing and shipping), developing conservation strategies, and monitoring population trends.
  • Molecular Biologists use genetic techniques to study the population structure, genetic diversity, and evolutionary history of marine mammal species.
  • Acousticians specialize in studying the acoustic behavior of marine mammals, including hearing abilities, vocalizations, echolocation, and the impact of anthropogenic (originating in human activity) noise on marine mammal communication.
  • Veterinarians provide medical care and conducts research on the health, diseases, medical care, and rehabilitation of marine mammals, often working in conjunction with wildlife rehabilitation centers or aquariums.
  • Policy Analysts analyze and develop policies and regulations related to marine mammal conservation and management, often working for government agencies or non-profit organizations.

It’s important to note that many marine mammalogists may have expertise in and work across multiple areas. Collaboration between different types of marine mammologists is often essential for comprehensive research and conservation efforts.

What is the workplace of a Marine Mammalogist like?

Marine mammalogists can be employed by a variety of organizations, including:

  • Academic Institutions – Universities and research institutes often employ marine mammalogists as faculty members, postdoctoral researchers, or research scientists. They conduct research, teach courses, and supervise graduate students studying marine mammalogy.
  • Government Agencies – Agencies such as the National Oceanic and Atmospheric Administration (NOAA), the US Fish and Wildlife Service (USFWS), and equivalent agencies in other countries employ marine mammalogists to conduct research, monitor populations, develop policies, and manage marine mammal conservation and protection efforts.
  • Non-Profit Organizations – Environmental organizations, conservation NGOs, and wildlife advocacy groups may employ marine mammalogists to conduct research, lead conservation projects, and advocate for policies to protect marine mammals and their habitats.
  • Zoos and Aquariums – Zoos and aquariums with marine mammal exhibits often employ marine mammalogists as curators, animal care specialists, researchers, and educators to manage captive populations, conduct research, and educate the public about marine mammals.
  • Consulting Firms – Environmental consulting firms may hire marine mammalogists to conduct impact assessments, monitor marine mammal populations during development projects, and provide expertise on regulatory compliance related to marine mammal protection laws.
  • Industry – Some marine mammalogists work in industries such as ecotourism, fisheries, oil and gas, renewable energy, and shipping, where they may be involved in assessing and mitigating the impacts of human activities on marine mammal populations.

Based on the nature of their work and focus, marine mammalogists may transition between different settings. Much of their time is likely to be spent in the field, specifically in diverse marine environments such as coastal regions, open oceans, polar regions, or remote islands. Fieldwork may involve boat surveys, beach surveys, aerial surveys, or underwater observations to study marine mammal populations, behavior, and habitats.

In addition, marine mammalogists may find themselves in research laboratories with specialized equipment for analyzing biological samples, conducting experiments, and processing data. They may use tools such as microscopes, genetic sequencers, acoustic recorders, and computer software for data analysis and modeling.

Other potential work settings include offices, classrooms, lecture halls, meeting spaces, and conference settings. It is common for marine mammologists to collaborate with colleagues in interdisciplinary teams.
