The research, published last month in the journal Behavioral Ecology and Sociobiology, looked at the behavior of 40 garter snakes—30 of them wild-caught, 10 captive-bred. When placed in an enclosure with a limited number of hiding places, the snakes not only formed groups, but returned to the same cliques after they were scrambled around. The findings match up with previous conclusions that reptiles can make friends and could be used to improve reptile relocation efforts.
