A heatmap of the titan arum plant, also known as the "corpse flower," shows that the plant's tall central spike, known as the "appendix," heats up to about 20 degrees Fahrenheit above ambient temperature when the flower blooms. Credit: Eric Schaller/Dartmouth.

The image shows two images of the Corpse Flower (Titan Arum) compared between natural light and thermal vision. On the left, the flower highlights its burgundy title and the inner, yellowish center in natural light. On the right, the thermal image shows the heat of the seed that attracts insects, in an impressive thermal expression.
