Shark Ecology course

Learn to better understand sharks — and see the underwater world with new eyes. In this course, you will discover how sharks live, why they are so important to the ecosystem, and how to approach them calmly and respectfully, should you ever be lucky enough to encounter one.

Sharks are among the most fascinating and at the same time most misunderstood animals in the ocean. With the SSI Shark Ecology Specialty program, you will not only get to know these impressive animals better, but also learn to approach them with more understanding and respect. Portrayals in films and media have long played a role in this, while the chance of an incident in reality is extremely small — comparable to other everyday fears, such as those of spiders or snakes. Fear of sharks is therefore understandable, but often disproportionate to the actual risk. For divers, sharks are not a threat, but rather a rare and special sight.

This course focuses on the ecological role of sharks worldwide, with, where possible, a translation to the situation in the Caribbean and around Curaçao. You will learn to recognize and identify different shark species, and gain insight into their behavior, senses, and way of moving through the water. In addition, you will delve into the role of sharks as top predators within the marine ecosystem. You will learn why healthy shark populations are essential for the balance of coral reefs and how their presence contributes to a healthy ocean system.

We also address the threats sharks face worldwide, such as overfishing, finning, and habitat loss. You will learn what impact this has on the ecosystem — and what you as a diver can do to contribute to protection and awareness. An important part of the course is understanding and interpreting shark behavior. This way, you learn how to better assess situations underwater and how to interact with sharks in a calm, respectful manner, should you ever encounter them while diving.

It is good to know that the chance of encountering a shark while diving in Curaçao is extremely small. Our instructors and guides see a shark only a few times a year on average, spread over hundreds of dives around the entire island. The species that are occasionally observed are usually harmless and calm, such as nurse sharks or occasionally a reef shark in the distance. Hammerhead sharks and even a tiger shark have also been seen once.

The relatively low chance of seeing sharks around Curaçao has several causes. In the past, sharks in the Caribbean have been intensively fished, so populations are recovering only slowly. In addition, the amount of large prey fish around the island is limited. Geography also plays an important role: Curaçao has a narrow reef zone where the reef quickly transitions into deep open water. Many sharks move precisely in that deeper, pelagic area and therefore often remain out of reach of recreational dives. So sharks are sometimes present, but usually just out of sight — and that makes an encounter here all the more special. Because we encounter sharks here so rarely, we do not have good photos of our own. That is why we use AI-generated illustrations on this page.

Upon completion, you will receive the SSI Shark Ecology Specialty certification, which counts towards the free SSI recognition certifications Specialty Diver, Advanced Specialty Diver, and Master Diver. As with all our ecology programs, we donate 20% of the course fee to a charity supported by our dive school. For this course, you can choose between BRANCH Coral Foundation or Sea Turtle Conservation Curaçao or another local organization committed to shark protection and marine conservation. By participating in this course, you are directly contributing to a healthier ocean.
