The ocean is home to nearly 95 percent of all life and as ocean ecosystems face increasing threats from climate change, pollution, coral bleaching, and biodiversity loss, marine science professionals are more important than ever.
Marine biology internships help students apply classroom knowledge to our real-world environments. Interns gain practical experience in:
These experiences help strengthen graduate school applications and improve employability within marine science, ecology, conservation, and environmental research careers.
Internships abroad also help improve soft skills which employers value just as much as technical abilities, studies or formation, because they determine how well a candidate will integrate into a team and handle challenges at work.
Employability skills make a real difference and help create a unique profile that aligns perfectly with the company's needs.

Work in biodiverse environments across the globe while contributing to UN SDG #14: Life Below Water.
Depending on the destination, interns may work in:
Gain direct experience working with marine researchers and conservation professionals, that can support future job opportunities and references.
The oceans' ability to adapt to change, and their resilience, are threatened by human activities (pollution, plastic waste, overfishing, and climate change due to human activities).
Coral reef bleaching (due to increased ocean temperature) and marine biodiversity decline are some of the consequences of human activities.
Efforts are being made to reduce and prevent drivers of marine biodiversity loss.
For students and recent graduates, marine biology internships in 2026 offer the opportunity to do more than observe — you actively contribute to research and conservation solutions.
When taking part in these internships, your work also supports the United Nations Sustainable Development Goal #14: Life Below Water. This goal focuses on conserving and sustainably using the oceans and marine resources.
Most marine biology internships are open to:
Typical requirements include:
Some programs may require or recommend scuba diving certification.Â
Marine biology internships are ideal for undergraduates who want to turn theory into practice.
Students gain the opportunity to:
These internships often help students decide whether to pursue postgraduate studies or specialized marine science careers.
I was able to acquire new knowledge in the field of marine biology and conservation (a field in which I'd like to work in the future), which may make the difference in my future job applications. (Clara). Read the full testimonial.
For recent graduates, internships act as a bridge between university and professional marine science careers.
Participants can:
I was able to achieve several goals, including obtaining my diving diplomas, improving my diving skills, and discovering the exciting field of marine biology in a relaxed atmosphere. (Laura). Read the full testimonial.
These programs offer hands-on experience in protecting marine ecosystems, with interns supporting research, conservation, and advocacy for marine life. Participants help reduce human impact while assisting with data collection, environmental monitoring, tagging, and conservation education.
Activities may include:
Focus on caring for injured or endangered marine animals.
Interns may assist with:
These internships are ideal for students interested in scientific careers.Â
Interns may:
Marine biology internships are available in coastal and island regions around the world, often in biodiversity-rich ecosystems.Â
Costa Rica – Known for coastal biodiversity and sea turtle conservation
Australia – Coral reef monitoring and restoration programs
South Africa – Shark, whale, and marine megafauna research
Spain (Canary Islands) – Dolphin protection and Mediterranean marine ecosystems
Mozambique – Underwater research linked to sustainable marine tourism
Each destination offers different ecosystems, allowing interns to gain exposure to a wide range of marine environments.
Marine biology internships can vary in length depending on program structure and academic goals.
Common durations include:
The longer the program, the deeper involvement in research and technical training.
