What Will You Learn?

Whether you’re drawn to the smallest plankton or the largest marine mammals, this course on marine biology will help you understand how marine life interacts with its environment, the impact of human activity, and the importance of conservation efforts.

Understand the Foundations of Marine Biology

You’ll begin by exploring the origins of the ocean and how Earth’s waters formed, as well as the unique physical and chemical properties that make marine ecosystems possible. This accredited marine biology course also introduces the diverse range of life in our seas, from microscopic organisms that produce much of our planet’s oxygen to complex vertebrates such as fish (ichthyology), seabirds, reptiles (herpetology), and marine mammals.

Explore Life Beneath the Surface

Through self-paced lessons, you’ll discover:

  • The structure and function of marine ecosystems.

  • How populations and communities interact in the ocean.

  • Food webs and their influence on global productivity.

  • Adaptations that allow marine life to thrive in challenging environments.

By the end, you’ll be familiar with the vast biodiversity of the oceans and the roles each species plays in maintaining healthy marine systems.

Investigate Human Impact and Conservation

This marine biology certification course also looks at the relationship between humans and the ocean, including overfishing, invasive species, and pollution. You’ll explore how climate change is altering marine habitats and what is being done to conserve these ecosystems for the future.

Upon completion of the course, you'll receive a diploma certificate in marine biology that you can use to showcase your achievement, support further learning, or add to your CV as evidence of your Continuing Professional Development (CPD).
