herbivorous animals. The salt marsh that is found within the Cape Byron Marine Park is the marine couch (Sporobolus virginicus var. minor) and the maritime rush (Juncus krausii). Algae is also found in the marine park, and in particular sargassum, the rare red algae (Rodriguezella), and the brown algae (Ecklonia radiata). Fauna The marine life of the Cape Byron Marine Park includes many species of dolphins, sharks, rays, turtles, eels, starfish, and corals fish, seabirds and marine plants. The Brunswick River is also home to several varieties of marine life including colourful nudibranchs (sea slugs), sea snails, shrimps, crabs, corals, starfish, anemones, octopus, flatworms, sea squirts and sponges. Fish The Cape Byron Marine Park has more than 530 recorded fish species. However, there are several species which are in decline and or threatened which are protected under the Fisheries Management Act 1994. These include the Bleeker's devil fish (Paraplesiops bleekeri), estuary cod (Epinephelus coioides), threatened black cod (Epinephelus daemelii) and the giant Queensland grouper (Epinephelus lanceolatus). The spotted wobbegong (Orectolobus maculatus) and banded wobbegong (Orectolobus ornatus) have been recorded to be in decline while the great white shark (Carcharhinus carcharias) has been listed as vulnerable under the Fisheries Management Act 1994. The grey nurse shark (Carcharius taurus) has also been listed under the Fisheries Management Act 1994 (NSW DPI 1994) as an endangered species and defined by the Environment Protection and Biodiversity Act 1999 as critically endangered with fears that there are less than 500 remaining in NSW waters. Mammals The Cape Byron Marine Park is also a part-time home to the humpback whale (Megaptera novaeangliae) which uses the Cape Byron Marine Park on their migratory journey from the Southern Ocean to their tropical breeding grounds. Reptiles Three of the sea turtles that live within the Cape Byron Marine Park which are considered threatened under the Threatened Species Conservation Act 1995 are the loggerhead turtle (Caretta caretta) which is defined as endangered and the green turtle (Chelonia mydas) and the leatherback turtle (Dermochelys coriacea) which are both defined as vulnerable. These turtles are also considered threatened under the Environment Protection and Biodiversity Conservation Act 1999 along with the hawksbill turtle (Eretmochelys imbricate) and the flatback turtle (Natator depressus). Birds The Cape Bryon Marine Park plays an important role for many birds by providing habitat, breeding grounds, food source and hunting grounds, as well seasonal movements for migratory species.
