Out of a total of seven sea turtle species, five of them occur in the coastal waters of Hawaii. However, the two most common species in the Hawaiian waters are green sea turtle and hawksbill sea turtle.

Hawaiian Green turtles are vegetarian species. Thus, when it comes to eating, they predominantly feed on red, green algae as well as beds of seagrass. Actually, coastal shallow waters of Hawaii contains 400 species of algae. Therefore, green turtles seem to prefer these vegetation growing on the reefs and rocks of Hawaiian waters.

Apart from these two species, some of the other aquatic turtles like olive ridleys, loggerheads and leatherbacks also make their home to the waters of Hawaii. However, these marine turtles mostly occur in offshore, deep waters.

On the southern and western coastlines of Maui island, the sighting of sea turtles offers great delight for the snorkelers and divers. In particular, the sighting of green turtles is quite common during snorkeling in Maui. The Hawaiian people often witness sea turtles reaching up to the water surface for breathing. The beaches of Hawaii also offer a great resting platform for sea turtles as they often bask in the sun.

It is a great fun to swim with sea turtles in Maui. However, make sure that you do not harass them by coming too close to them because it is illegal in Hawaii. In case of violating the sea turtle rules, there can be a fine of $100,000 in the state of Hawaii. Besides, while swimming, stay at a distance of not less than 15 feet from marine turtles and do not spread out your arms.
