Which anatomical feature allows the Lundehund to scout effectively in narrow crevices?

Answer

The hyper-flexibility of the spine and neck

The extreme pliancy found throughout the Lundehund's spine and neck is crucial for maneuverability in tight environments. This hyper-flexibility, combined with the ability to fold its head backward, allows the dog to twist and arch in seemingly impossible ways. This structural trait enables the dog to scout, or gain visibility, deep into narrow crevices or small nooks on sea cliffs where larger or less flexible animals cannot penetrate to pursue prey.
