Distribution and Habitat
Inhabiting the continental shelf, the Australian blacktip shark is found from Thevenard Island in Western Australia to Sydney in New South Wales. Within its range, it co-occurs with the common blacktip shark; the ratio between C. limbatus and C. tilstoni was once thought to be 1:300, but recent genetic studies have found it to be closer to 50:50. This species has been reported from the intertidal zone to a depth of 150 m (490 ft); larger sharks tend to occur in deeper water. Though it occupies the entire water column, it is most common close to the surface or in midwater. Genetic data suggest Australian blacktip sharks across northern Australia are all members of a single population. Tagging studies have found this species mostly moves only short distances along the coastline and rarely enters offshore waters. However, some individuals have been recorded traveling longer distances, up to 1,348 km (838 mi).

Famous quotes containing the words distribution and/or habitat:
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
