Rattlesnakes showed signs of reduced stress when they were kept with a companion, according to a new study
Snakes: They’re just like us — at least in one respect. Like humans, the slithery reptiles may rely on others of their kind to stay calm in times of stress, according to a new study published Thursday in the journal Frontiers in Ethology. The study authors focused their research on Southern Pacific rattlesnakes, or Crotalus helleri, which are common in Southern California.
They used an over-the-counter heart rate monitor to track the animals’ stress levels while testing the subjects in three ways: alone, with a companion, and with a rope about the same size as a fellow snake . They found that the snakes’ heart rates were substantially reduced when they were placed in the bucket with a companion compared with being alone or with the rope. And that result held true for both the lowland and mountain-dwelling snakes as well as males and females.
