Sea Turtles

The video explores the fascinating journey of loggerhead turtles, focusing on their innate ability to navigate using Earth's magnetic field. Biologist Ken Lohmann studies how these turtles, from birth, are programmed to embark on a long journey around the Atlantic Ocean. The turtles' responses to specific magnetic fields help them avoid dangerous waters and guide them along the Gulf Stream. Experiments demonstrate their ability to simulate swimming behavior in response to environmental cues, highlighting their natural 'turtle positioning system'. Understanding these mechanisms is crucial for species protection.

What is the primary focus of Ken Lohmann's research on loggerhead turtles?

• Their social interactions

• Their use of the Earth's magnetic field for navigation

• Their nesting behavior

• Their diet and feeding habits

How do loggerhead turtles respond to the magnetic field near Portugal?

• They turn south

• They stop moving

• They swim in circles

What is the significance of the southeasterly orientation for turtles near Florida?

• It prevents them from getting lost

• It guides them into the Gulf Stream

• It helps them find food

• It leads them to warmer waters

What does the wave simulator experiment demonstrate about turtle behavior?

• Turtles can fly

• Turtles prefer calm waters
