SSI - Your Choice for Certification

Dive into the deep and explore the world’s best deep dives
Push your limits and go beyond what an average diver will ever experience - discover the mystique of deep diving. Many secretive dive sites await you in deeper water - especially exciting wrecks and dark caves but also the magic of cenotes and astonishing steep walls can be explored beyond the recreational limits. Expect to see large marine life such as the ocean sunfish but also Pacific seahorses live up to 60m (200ft) deep. Some of the most popular spots for deep diving include the Blue Hole in Belize, Gordon Rocks in Galapagos or the cenotes in Mexico.

Aquatic life under our oceans, lakes, rivers, and streams is amazing! From microscopic zooplankton to the largest animal on earth, the blue whale, underwater life comes in all possible shapes and sizes. With 71% of the earth being covered with water, it is no wonder we are so fascinated with what lies beneath the surface. In fact, scientists estimate that there are nearly 1 million different species of aquatic animals. Freshwater ecosystems are home mainly to fish, invertebrates, and reptiles, whereas the ocean contains a wide array of marine life including fish, mollusks, crustaceans, reptiles, sharks, and marine mammals like whales, dolphins, seals, and manatees.
