"S. purpurea" also trap juvenile spotted salamanders with enough regularity that nearly 20% of surveyed plants were found to contain one or more salamanders in a 2019 study. The salamanders were observed to die within three to nineteen days, and may be killed as the small pools of water in the plant are heated by the sun. A single salamander could provide hundreds to thousands of times the nutrients of invertebrate prey, but it is not known how efficiently "S. purpurea" is able to digest them.
