Goff Et Al

Multiple Choice

Goff et al. (1998) performed an experiment in which hatchling loggerhead sea turtles swam into surface waves in tanks for either 15 minutes or for 30 minutes. Their orientation was then tested in still water and in a magnetic field.

A) Hatchlings with no more than 15 minutes of experience swimming into waves in a magnetic field were able to maintain their orientation in still water.
B) Only those hatchlings with 30 minutes of experience swimming into waves in a magnetic field were able to maintain their orientation in still water.
C) The experiment demonstrated that either experience with swimming into waves or with the magnetic field was enough to keep them oriented in still water.
D) The turtles were able to maintain their orientation in still water on the basis of the magnetic field alone, even if they had not had experience swimming into waves.
