"When we go out in the ocean or on the surf, we're in the shark's habitat," he adds. "That's where they live. We're enjoying their home and inevitably, it's possible for us to come into contact ...
Sand tiger sharks store air in their stomachs, using it as a form of swim bladder. Bottom-dwelling sharks, like the nurse shark, have negative buoyancy, allowing them to rest on the ocean floor. Some sharks, if inverted or stroked on the nose, enter a natural state of tonic immobility. Researchers use this condition to handle sharks safely. [40]
Sharks! consists of five life-sized fibreglass model sharks. [2] The project was inspired by The Headington Shark in Oxford. [1] The installation cost £25,000. [3] It was selected and built as the 2020 Antepavilion, fitting the year's theme of "tension of authoritarian governance of the built environment and aesthetic libertarianism".
There are four species referred to as sand tiger sharks: [2] The sand tiger shark Carcharias taurus; The Indian sand tiger shark Carcharias tricuspidatus. Very little is known about this species which, described before 1900, is probably the same as (a synonym of) the sand tiger C. taurus [2] The small-toothed sand tiger shark Odontaspis ferox.

They are often found in warm or temperate waters throughout the world's oceans, except the eastern Pacific . [ 3 ]
Sand sharks: 2 3 Sand sharks are so-called because they inhabit sandy shorelines, and are often seen trolling the ocean floor in the surf zone. They are found in warm or temperate waters throughout the world's oceans, except the eastern Pacific. [19] Sand sharks have a large second dorsal fin. They grow up to 10 feet in adult length. [20]
The Port Jackson shark is a nocturnal species which peaks in activity during the late evening hours before midnight and decreases in activity before sunrise. [2] A study showed that captive and wild individuals displayed similar movement patterns and the sharks' movements were affected by time of day, sex, and sex-specific migrational behaviour.
In the central Atlantic Ocean, the frilled shark has been caught along the region of the Mid-Atlantic Ridge, ranging from north of the Azores islands to the Rio Grande Rise, off southern Brazil, and the Vavilov Ridge, off West Africa. Frilled sharks tend to be very solitary organisms; interacting with multiple individuals of their kind is rare.
