Prey capture attempts can be detected in Steller sea lions and other marine predators using accelerometers
International audience We attached accelerometers to the head and jaw of a Steller sea lion (Eumetopias jubatus) to determine whether feeding attempts in a controlled setting could be quantiWed by acceleration features characteristic of head and jaw movements. Most of the 19 experimental feeding eve...
