Adding to what Joe said,  the two Gougarufus seem to have different electric charges, since the magnetic field around them only appears when they fight together. Loro seems to be calling for its partner at :50 - :53, signaling them to join the fight. Perhaps that's one of the tactics they use to hunt more difficult prey, one chases the prey and the other ambushes it.
