PADI Underwater Naturalist Course


The PADI Underwater Naturalist course lets you understand about the local underwater ecosystem, as well as the differences between terrestrial and aquatic worlds. You will learn more about underwater ecology, symbioses among underwater plants and animals, and their habitat.

It is a great feeling to be able to identify the fish, plants, and other creatures that you see underwater during your dive; however, you can make your dive even more meaningful by being able to understand the interactions between these living things.  Take the pelagic thresher sharks you see in Malapascua, Cebu as an example.  Have you ever asked why they can only be spotted early in the morning and what they are up to in that area when they are supposed to be just hunting in the deep?  They actually go to Monad Shoal in order to have some cleaning sessions with the smaller moon-wrasse and blue-wrasse.  It is also amazing that these sharks do not feed on those little fishes.
