Understanding Hurricanes and Marine Life

The video discusses the impact of hurricanes on marine life, focusing on how different species like sharks and dolphins detect and respond to storms. It explains the effects of storms on ocean water, including wave formation and sediment disturbance, which can harm marine life. The video highlights the vulnerability of coral reefs to hurricanes and the role of artificial reefs in supporting marine ecosystems. Despite challenges, artificial reefs offer hope for marine habitat conservation.

What is the primary challenge faced by underwater creatures during hurricanes?

• Lack of food

• Increased salinity

• Deficit of opposable thumbs

• Surplus of gills

How do sharks detect approaching storms?

• Using their sense of smell

• By observing other fish

• Through their lateral lines

• By sensing changes in water temperature

What unique method do dolphins use to sense storms?

• Detecting changes in water salinity

• Listening to the wind

• Following other marine animals

• Observing the sky

What happens to ocean water when a hurricane is overhead?

• It freezes

• It moves in a circular motion

• It evaporates

• It becomes warmer

Why do many marine creatures flee to deeper waters during a hurricane?

• To find more food

• To avoid predators

• To escape the circular water motion

• To enjoy cooler temperatures

What is the primary way coral spreads to new locations?

• By floating on the surface

• Through fish migration

• By human intervention

• Via coral fragments taking root

What risk does fragmented coral face after a hurricane?

• Being eaten by fish

• Being carried to land

• Becoming buried in sediment

• Drying out

What is a common material used to create artificial reefs?

• Wooden planks

• Plastic bottles

• Glass jars

• Old ships

What was the main issue with the Osborne Reef project?

• It was built in the wrong location

• It was too expensive

• The steel cables rusted

• It attracted too many fish

What is the purpose of sinking objects in strategic locations for artificial reefs?

• To block ocean currents

• To attract marine life and form new habitats

• To dispose of waste

• To create tourist attractions
