Hurricanes can generate massive waves, so most sea creatures — including dolphins, whales, and sharks — avoid the rough surface water and swim to calmer seas. But what happens to the underwater creatures -- like sharks -- when the seas surge due to the force of a hurricane?
Which mix warm surface water with colder, saltier water below generating currents that extend up to 91 meters below the surface. Style Book. A study in 2001 in young blacktip sharks at Mote Marine Laboratory showed that the fish take evasive action when faced with an approaching hurricane.
Where they can become disorientated, and even die.

It is probably the most absurd film plot of the year: What is a thermocline? Dr Lauren Smith , a shark expert who studied the pressure sensing abilities of lemon sharks at Aberdeen University, found the fish change their behaviour in response to changes in pressure.

Fish and other ocean creatures face deadly conditions during a hurricane — sometimes the extreme weather strands them on land or far out at sea. Slow-moving fish and turtles and shellfish beds are often decimated by the rough undercurrents and rapid changes in water temperature and salinity wrought by a hurricane.
By Richard Gray , Science Correspondent. Sign Up Now. The International Shark Attack File has highlighted these trends However, when viewed alone, this decline in shark attacks may primarily be due to fewer people being in the sea during stormy weather, rather than anything to do with the sharks themselves.
More from the web. In sharks this is particularly sensitive and allows them to sense wounded or sick fish from the vibrations they produce. By Abigail Abrams September 7, 2017. OCEARCH tracks and studies sharks in hopes of creating a large enough database for scientific communities across the globe to learn new things about the creatures.
