Callorhinchus milii, also known as the Australian ghost shark or elephant fish, is found in the waters off southern Australia and New Zealand. It is notable for its elongated, flexible snout resembling an elephant's trunk, used to detect prey on the ocean floor. This species typically inhabits sandy or muddy seabeds and plays a crucial role in marine ecosystems by controlling benthic invertebrate populations.

Callorhinchus milii, commonly known as the Australian ghostshark or elephant fish, is native to the continental shelf waters of southern Australia and New Zealand. It is primarily found off the southern coasts of Australia, including Tasmania, as well as around both the North and South Islands of New Zealand.

Callorhinchus milii inhabits temperate marine environments, typically found at depths ranging from 20 to 200 meters. The species prefers sandy or muddy substrates on the continental shelf, often near rocky reefs or seagrass beds. The water temperature in these regions generally ranges from 10 to 20 degrees Celsius.

The Australian ghostshark occupies a demersal niche, feeding on benthic invertebrates and small fish. It uses its elongated, flexible snout to detect prey buried in the substrate. The species plays a role in controlling the population of benthic organisms and contributes to the ecological balance of its habitat. Its adaptations include a cartilaginous skeleton and a unique reproductive strategy involving egg cases deposited on the sea floor.
