Marine Biology

This course is about life in the oceans, from the sunlit surface to the inky depths, from microscopic phytoplankton to the great blue whale. The ocean is among the world’s most inhospitable environments for scientific research, which is why we know as much about the surface of the moon as we do the bottom of the sea. This course uncovers the evolutionary history of marine organisms, adaptations to life in water, the behavior and functional morphology of sea animals, interactions between species, and current threats. Throughout the course, we meet scientists who are developing ingenious solutions for overcoming challenges and are making remarkable discoveries. By evaluating these cases and analyzing real scientific data, we come to understand some of the ways that life has adapted to diverse ocean habitats, how it interacts with the physical environment and with other organisms, and why it matters to us.

The course was excellent and well structured. Only issue is that charging $49 for a certificate is really unprofessional. This is not a university degree program.

I think this was a very informative course. I learned a lot of new things that i wasen't fully aware of and i am now a lot more interested in learning more.

Wonderful course! Truly gave me a foundational knowledge of many topics pertinent to the field of Marine Biology. Beyond that, it was also enjoyable and engaging.

A fascinating, sometimes beautiful, sometimes disturbing summary of ocean life, resources, and threats from pollution and overfishing.

The subject I studied has been invaluable. To be honest, I have learned more about marine ecosystems than I ever have before.

A brief but very educational course. I'm very glad I took it. I hope I get more courses on this topic here though. Hopefully credited ones.

I studied a bachelor degree in marine science back home in Spain. I took this course just to refresh some aspects and terms. Such a great content!

It was good, it had a lot of information but it's kinda hard to understand and it would be a lot better if they added more videos and things other than text.

Gave me vast insights about the Oceans and Marine Life and really a good course if one is interested in Conservation Biology and Sustainability.
