Marine biologists are scientists who dedicate their careers to studying ocean life and aquatic ecosystems. It's a career that combines adventure with serious scientific research.
Since marine biology covers such a vast area, most researchers choose to specialise in particular aspects. You might focus on coral reefs, deep-sea creatures, or marine conservation, depending on what fascinates you most.
Did you know? Marine biologists don't just study fish - they research everything from microscopic plankton to giant squids!

Marine biologists wear many different hats in their work. They conduct experiments both in laboratories and out in the field, often spending time on research vessels or diving underwater.
A huge part of the job involves rescuing and caring for sick or injured marine animals. This means you might find yourself rehabilitating dolphins, treating diseased coral, or helping oil-spill victims recover.
Monitoring animal behaviours is another crucial responsibility. Scientists track migration patterns, study feeding habits, and observe how marine life responds to environmental changes. After releasing rescued animals back into the wild, they continue monitoring to ensure successful reintegration.
Real impact: Your research could help save endangered species or discover new treatments for human diseases!

Becoming a marine biologist requires a diverse skill set that combines scientific knowledge with practical abilities. Strong swimming skills and scuba diving certification are often essential, since you'll spend considerable time in and around water.
You'll need excellent technology and coding skills to analyse data, use sophisticated research equipment, and create computer models. Modern marine biology relies heavily on advanced technology for everything from tracking marine animals to studying ocean chemistry.
Analytical and problem-solving skills are crucial for interpreting research results and designing experiments. You'll also need strong communication skills to share your findings with other scientists, write research papers, and sometimes educate the public.
Attention to detail and determination will serve you well during long research projects. Since most marine biology work involves collaboration, strong teamwork skills are absolutely vital for success.
Top tip: Start developing these skills now - join your school's science club or volunteer at local aquariums!

Marine biology encompasses the study of all life forms that inhabit oceans, seas, and other aquatic environments. This isn't limited to saltwater - marine biologists also study organisms in lakes, ponds, and areas where freshwater and saltwater mix.
The diversity of subjects is absolutely mind-blowing. You could spend your career studying microscopic bacteria that form the base of ocean food chains, or focus on massive whales that migrate thousands of miles each year.
Marine biologists make groundbreaking discoveries about ocean ecosystems, from understanding how coral reefs function to uncovering the secrets of deep-sea creatures that live in complete darkness.
Exciting fact: Scientists estimate we've only explored about 5% of our oceans - there's so much left to discover!

As our global population grows, we're increasingly turning to oceans to sustain our basic needs. The sea provides food, drinking water, energy sources, and even helps with waste disposal and transportation.
Advances in technology are constantly improving our ability to harness ocean resources responsibly. From offshore wind farms to sustainable fishing practices, marine biologists play a crucial role in developing these innovations.
It's up to current and future generations to build upon existing ocean knowledge. Marine biologists are at the forefront of reaching the full potential of our oceans and coastal areas, ensuring we can benefit from marine resources whilst protecting these vital ecosystems.
The work you do as a marine biologist could literally help save the planet - and that's not an exaggeration!
Your future: Today's marine biology students will be tomorrow's ocean conservation heroes!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
