Ask most people what it’s like to work with whales, dolphins, or seals, and they’ll picture an aquarium trainer. That’s one path, but marine mammal careers reach much further, into research, veterinary care, rehabilitation, offshore monitoring, and conservation. Each one requires a different mix of education and experience, so the role you’re aiming for shapes the degree you choose and how you build your background.
Whichever role you aim for, the science behind these careers offers steady opportunity. The U.S. Bureau of Labor Statistics (BLS) projects that employment of zoologists and wildlife biologists, the occupation that includes marine mammal scientists, will grow 4% from 2025 to 2035, with about 1,400 openings annually.
Reaching those roles usually starts with a bachelor’s degree in marine biology or a related science, and some programs include coursework focused specifically on these animals, such as the Bachelor of Science in Marine Biology and Sustainable Aquaculture at Unity Environmental University, which offers a course in marine mammal and seabird biology.
What It Means to Work With Marine Mammals
Working with marine mammals means working with some of the ocean’s most protected animals, from whales, dolphins, and porpoises to seals, sea lions, manatees, and sea otters. According to NOAA Fisheries, all marine mammals are protected under the Marine Mammal Protection Act. That’s why so many marine mammal careers involve permits, population monitoring, stranding response, and coordination with federal agencies, alongside the research and animal care most people picture.
At the center of the scientific side is the marine mammalogist, a biologist who specializes in these animals. You’ll also see the titles marine mammal scientist and marine mammal biologist, which generally describe the same work: studying behavior, populations, health, and how human activity affects these species.
Because the field blends biology with data analysis, animal care, and regulation, it suits people with different strengths, from analytical researchers to those who prefer working directly with animals or the public.
What Jobs Can You Get Working With Marine Mammals, and What Do They Pay?
Not every marine mammal job puts you face-to-face with the animals every day. Some roles center on direct care, while others focus on data, health, or regulatory compliance, and many professionals move between them as their careers grow. Here are the roles you’re most likely to come across:
| Role | What the Work Looks Like |
| Marine mammalogist or marine mammal biologist | Studies behavior, populations, and health through fieldwork, tracking, and data analysis |
| Marine mammal trainer | Cares for and trains animals at aquariums and zoos, often leading public education programs |
| Marine mammal veterinarian | Diagnoses and treats illness and injury in captive and stranded animals |
| Rehabilitation specialist | Rescues and cares for sick, injured, or stranded animals until they can be released |
| Marine mammal observer | Monitors for animals during offshore construction, seismic surveys, and shipping activity |
Pay varies just as much from one role to the next. BLS doesn’t track marine mammal roles separately, but related occupations offer a useful guide. For marine mammalogist salary data, the closest category, zoologists and wildlife biologists, earned a median of $76,780 in May 2025. Animal trainers, the category that includes dolphin trainers, earned a median of $39,990, and veterinarians earned a median of $130,100 in the same period.
What Degree Do You Need for a Marine Mammal Career?
Most marine mammal careers begin with a science degree, but the specific major is more flexible than many people expect. According to the BLS, zoologists and wildlife biologists, the occupation that includes marine mammal scientists, typically need a bachelor’s degree to enter the field. Students often major in zoology, wildlife biology, biology, or a related science, and coursework usually combines lab and field work with math and statistics.
Few schools offer a standalone marine mammalogy degree, so most people start with a broader science program and narrow their focus over time through electives, research projects, and field experience. If you’re comparing marine mammal degree options, look for programs that include courses on these species, since that coursework gives you a head start on the specialization employers look for.
As your career develops, education levels tend to line up with roles like this:
- Bachelor’s degree: A bachelor’s degree is the usual entry point for trainer, technician, observer, and research assistant roles. Common majors include biology, marine biology, and zoology, with psychology and animal behavior especially well suited to marine mammal training work
- Master’s degree: Opens doors to specialized research, consulting, and government agency positions. It also lets you focus on a specific area, such as acoustics, population ecology, or animal health, which can make you more competitive for permanent roles.
- Doctoral degree: Typically required to lead independent research or teach at the university level, and the standard for veterinarians, who need a Doctor of Veterinary Medicine (DVM).
For anyone planning how to become a marine mammalogist, the most common route is a science bachelor’s followed by graduate study, with field experience built along the way.
The Skills and Experience That Set Marine Mammal Candidates Apart
In a field this competitive, the experience you bring often carries as much weight as your degree. Employers want proof that you can handle the work, and these are the areas where that proof usually comes from.
Internships and volunteer work at aquariums, research centers, and rehabilitation facilities are among the most common ways into the field. Marine mammal internships give you direct experience in research and animal care, and volunteering with a stranding response network or rehabilitation center often leads to paid jobs in marine mammal rehabilitation.
Data and technical skills help you contribute to research teams from the start. Statistics, geographic information systems (GIS), and tools such as passive acoustic monitoring, which tracks animals by the sounds they make, are increasingly part of everyday work in this field.
Specialized training and certifications can set you apart for field roles. Scientific diving and boat handling are valuable in research settings, and marine mammal observer positions usually require specialized observer training before you can work on offshore projects.
Communication skills matter in nearly every role, since research reports, grant applications, and education programs all depend on clear writing and public speaking.
The earlier you start building this record, the stronger your applications become. Taking on a volunteer role or assisting with a research project while you’re still earning your degree shows employers you’re committed to the field, not just interested in it.
Where Do Marine Mammal Professionals Work?
Government agencies are the largest employer in this field by a wide margin. According to the BLS, 66% of zoologists and wildlife biologists work for government, followed by consulting firms (10%) and nonprofit organizations (7%). Each type of employer offers a different kind of career experience:
- Federal and state agencies: Positions tend to be more stable and long-term, and the work is closely tied to legal protections and management decisions. Federal openings are posted on USAJOBS, where hiring follows a structured application process.
- Consulting firms: Work is project-based and often involves travel or extended time offshore, with assignments that change as each project wraps up.
- Nonprofit organizations: Teams are usually smaller and mission-focused, and positions often depend on grants and donations so that roles can be broad and varied.
- Aquariums and zoos: These settings are public-facing, and schedules often include weekends and holidays, since animals need care every day.
- Universities and research institutes: Work typically follows grant-funded projects and academic timelines, and these roles often connect to graduate study.
Many early-career positions in this field are seasonal or project-based, which makes them a practical way to build experience across different employers and settings. Staying open to relocating and developing skills that carry over into broader marine biology careers can broaden your options as your career grows.
