Ningaloo Marine Park Offshore, the Ningaloo Reef stretches from north to south for 260km and protects a lagoon rich in marine life. Fantastic coral formations, rare starfish, Dugongs, Whale Sharks, playful Dolphins and giant Hump- Backed Whales are some of the fascinating marine life that inhabit the waters. In season, sheltered sand beaches serve as nesting rookeries for turtles. Several historic ship wrecks can also be found in the Park. Leisure fishermen, angling for their own needs, are welcome in the Marine Park's recreation and general use zones. Special regulations apply and fishing and collecting are not permitted in the Park's eight sanctuary zones. Fish are plentiful and common species include Sweetlip, Spangled Emperor and several types of Trevally. In deeper water, Spanish Mackerel, Wahoo, Tuna and Sailfish can be caught. Some 220 species of coral and 500 species of fish have been recorded in the Park. The world's biggest fish, the Whale Shark, regularly swims in these waters. Growing up to 40,000kg and 18m long, these monsters of the deep drift slowly across ocean currents filtering water for the plankton they feed on. Marine mammals such as Dolphins, Humpback Whales and the Dugong can often be seen cavorting in or near the reef lagoon. During summer, green and Loggerhead Turtles make their way up the beaches to lay their eggs.
