Zombie worms can detect the heat gradients in sediments around whale bones to find their nutrient source in complete darkness.
Zombie worms, or Osedax species, feed exclusively on decaying whale bones in deep-sea environments. Juvenile researchers discovered that these worms have infrared-sensitive structures enabling detection of minute heat differences in sediment caused by decomposing organic matter. Infrared perception guides the worms toward nutrient-rich bones for colonization and reproduction. Combined with chemosensory input, this allows precise localization in extreme darkness. Observations indicate sensitivity to temperature variations as slight as 0.001°C. This adaptation maximizes energy efficiency in resource-scarce environments. Evolution has fine-tuned these worms to exploit ephemeral whale falls. Thermal detection enhances survival and reproductive success. Infrared cues ensure that zombie worms locate essential resources even in vast, dark deep-sea habitats.
