Sea lions trained to probe decline in species
Canadian researchers have trained sea lions to take part in an experiment designed to find out why the species is dying out.
The team strapped cameras and tracking equipment onto endangered Steller sea lions to see how they dived for food.
Early results from the project indicate that overfishing might not be the main factor in their decline as had previously been thought.
