Introduction to Coral Ecology
Understand the reef beyond what you see underwater.
A beginner-friendly intro to coral reefs: what they are, why they matter, what threat they face, what are the main type, and how you can help protect them.
Sea Turtle Ecology
Go beyond loving sea turtles. Understand them.
Understand the ecological importance of sea turtles, the threats they are facing, the existing conservation efforts, and how to help protect them.
Learn it. Then see it underwater.
Take your Coral Ecology course into the reef.
What if learning about coral ecology didn't stop when the lesson ended?
Join me in Utila for an optional in-water session (snorkeling or diving) where we apply what you've learned directly on the reef.
In the water, you'll practice things like:
✓ Recognizing stony vs soft corals
✓ Identifying stony coral types
✓ Observing signs of healthy, stressed and degraded reefs
✓ Connecting ecological concepts to what you see around you
This real life session helps you integrate what you learned, gain confidence underwater, and connect even more with the reef you are helping to protect.
Learn with someone who lives and breathes the ocean.
I'm Mariam, a marine biologist and dive instructor based in Utila, Honduras.
I created Reef Matters to make marine ecology accessible to anyone who wants to understand the ocean better — whether you're a diver, snorkeler, ocean lover or simply curious.
Because the more we understand the ecosystems around us, the more connected we become to protecting them.

What students say
"I had the wonderful opportunity to take Reef Matters in person class. It was such an eye opening experience from a scientific and conservation perspective. My diving and snorkeling adventures have completely changed and become even more enriching. Mariam’s scientific background, passion, and wonderful personality made the class a delightful and insightful experience. I highly recommend taking the class in person in Utila or online if you are elsewhere. It’s a must do!"Thank you!! "
"I recently completed Introduction to Coral Ecology course, and I can honestly say it was an incredibly impactful experience. The course offers a thoughtful and engaging look at coral reefs — not just their beauty, but their complexity, fragility, and global importance.Mariam is a truly knowledgeable instructor who brings both scientific depth and genuine passion to her teaching. She has a wonderful way of explaining intricate ecological relationships in a way that feels clear, accessible, and inspiring.What stood out most to me was the use of creative learning strategies throughout the course. Rather than simply presenting information, Mariam encourages you to think critically, reflect, and truly connect with the material. By the end, I genuinely felt like I was seeing reefs through a different lens — with more understanding, more urgency, and also more hope.
I would highly recommend this course to anyone who cares about the ocean and wants to deepen their knowledge in a meaningful, motivating way.

"In just 3 hours, I gained a better understanding of Coral ecology and why coral matters. Mariam is very knowledgeable and the class was well organized, concise and provided specific tips that can be used to protect the reef. There were many opportunities to ask questions and I left the class with ideas that I can implement right away. Mariam provides a good balance between presentation, practical exercises and discussion and the workbook is a great resource. It’s great value for the time invested."
