Discover the world’s most fascinating aquatic life

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.

The leatherback sea turtle is the largest of all the turtles on earth, both aquatic and terrestrial.

Who has never been overjoyed to see a turtle while snorkeling or diving? These friendly-looking, ancient reptiles are found worldwide in tropical and subtropical areas. Sea turtles can live for up to 100 years and are believed to have been living here on earth for millions of years. Many facts about them are astonishing but probably the most is the fact that female turtles return to the exact beach where they were born, a journey sometimes covering thousands of kilometers, to lay their eggs in shallow nests they dig in the sand with their flippers. This is an incredible achievement and an awe-inspiring thing to watch. Most locations where you can dive with sea turtles are also where you can sneak a peek at this miraculous egg-laying practice that’s as old as time itself.
