Biological Diving

Do you ever wonder if there is more to what you see underwater? Why reefs are so colourful or how fish interact with one another? Or do you find yourself getting a little bored with just the average guided dive?

Black Rock Dive Centre offer a selection of biological guided dives to answer some of these questions and provide you with a new aspect that you may not have thought of before. You can choose between 5 different topics, Reef Structure, Conservation, Evolution, Behavior and Fish and Coral ID. Each guided dive is aimed specifically at the reefs of Dahab and the Red Sea with information and examples that you can take onto later dives throughout your holiday.

Reef Structure focusses on the different parts of the reef and why they are so important. It looks at the basic structure of coral and gives you a look at the range of diversity on the reef. This course is suited towards divers that have an interest in how coral reefs run and the different dynamics that hold it together as such a complex and interesting ecosystem.

Conservation dives will look at the damage that is being done to coral around the world and then the threats facing Dahab and the Red Sea reefs especially. You will learn to identify different coral diseases and be able to tell the difference between human and biological damage to the reef. You will also look at how individuals can help conserve the reef on a daily basis.

Have you ever wondered how the ecosystem came to be in the very first place? How so many species of fish evolved or why there are so many different colours and patterns underwater? The Evolution biological guided dive looks at these topics and more. We look at evidence of evolution happening right now and on the dive will observe differences between species that have evolved over millions of years.

Behavior dives look at many different aspects of a fishes life cycle and will explain interactions that you see underwater.  From camouflage to mating displays, territory disputes to feeding, the behavior dive will give you a whole new side to diving that you may not have thought of before. Behavior is also crucial to understand for photographers, as in order to get that perfect shot, you need to be able to understand what your subject is doing in order to anticipate its movements.

Fish ID and Coral ID will allow you to learn many of the species that are found here in Dahab and will also teach you how to identify them. From forked tails to eye positions, the Identification dive will ensure that log book entries are far more detailed when naming all the different fish and corals!

All biological guided dives will consist of a presentation and then a dive at a site specifically chosen to best show you what you have learnt. During the dive, we will focus on what you learnt during the presentation through activities and observations underwater. If you are looking to learn more about the world you enjoy then these dives are for you. They can give you a whole new understanding of the reef ecosystem and so bring an entirely new aspect to diving.
