Turtle Behavior and Shark Predation

Shark Bay, located off Australia's western coast, is home to diverse marine life, including sea turtles and tiger sharks. Researchers are investigating why loggerhead turtles are more frequently preyed upon by tiger sharks compared to green turtles. Using Critter Cam technology, they discovered that loggerheads spend more time at the surface, making them vulnerable, while green turtles quickly dive back to safety. This study highlights the behavioral differences that affect turtle survival in Shark Bay.

What is the primary difference between green and loggerhead turtles mentioned in the video?

• Their diet

• Their speed and agility

• Their size

• Their color

What technology is used to study the turtles in Shark Bay?

• GPS Tracking

• Critter Cam

• Satellite Imaging

• Sonar

How is the Critter Cam attached to the loggerhead turtles?

• With a harmless epoxy and base plate

• With a harness

• With a magnetic clip

• With a suction cup

What makes tiger sharks effective hunters of large prey?

• Their camouflage

• Their size and serrated teeth

• Their speed

• Their ability to swim in shallow waters

Why are loggerhead turtles more frequently targeted by tiger sharks?

• They are smaller

• They are noisier

• They are more abundant

• They swim closer to the surface for longer periods

What behavior of green turtles helps them avoid tiger shark attacks?

• Staying close to the shore

• Swimming in groups

• Being more aggressive

• Spending minimal time at the surface

What is the main reason loggerhead turtles are more vulnerable to tiger sharks?

• Their slower speed

• Their smaller size

• Their brighter color

• Their softer shell

What is the primary advantage of the green turtle's behavior in avoiding predators?

• Their aggressive nature

• Their ability to camouflage

• Their speed and agility

• Their larger size

What does the Critter Cam footage reveal about the green turtles' behavior?

• They stay close to the shore

• They swim in circles

• They dive quickly after taking a breath

• They spend a lot of time at the surface

What is the main focus of the research conducted in Shark Bay?

• The predation of loggerhead turtles by tiger sharks

• The breeding habits of green turtles
