For centuries, sharks have been known as silent predators, moving through the ocean with stealth and precision. Scientists believed these majestic creatures lacked the ability to make sound because they do not have the organs typically associated with vocalization. However, a groundbreaking study now challenges this long-held assumption, revealing yet another fascinating aspect of God’s creation.
According to research published in the Royal Society Open Science journal, scientists have recorded what is believed to be the first-ever evidence of sharks producing sound. This discovery was made while studying rig sharks, small bottom-dwelling sharks found off the coast of New Zealand. These sharks were observed making a distinct clicking noise when handled by researchers underwater (Royal Society Open Science, 2024).
Lead researcher Carolin Nieder explained, “Sharks have sensory systems that are more refined than their hearing, like their electroreceptors, their smell, and the way they propel themselves through the water. But I think the original notion that we had that sound isn’t important at all is also likely not true” (Live Science, 2024). The scientists believe the sharks produce these clicks by forcefully snapping their flattened teeth together, possibly as a stress response or a warning signal to predators.
As Catholics, we recognize that all of creation reflects the wisdom and providence of God. Scripture reminds us that, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalm 19:1). This newfound ability in sharks adds to the countless wonders of the natural world, showing that even the creatures we assume to be silent may have been given unique ways to communicate.
During the study, ten juvenile rig sharks were observed making these sounds, with all of them producing audible clicks when being handled. Interestingly, as the experiments progressed, the sharks clicked less frequently. Nieder theorized, “Maybe they weren’t afraid for their lives anymore” (Live Science, 2024). This suggests that in the wild, these clicks may serve as a defense mechanism to distract potential predators.
The study also challenges the previous assumption that sharks are entirely silent due to their lack of swim bladders—the air-filled sacs that many fish use to make sounds. Instead, researchers now propose that some sharks may use their teeth as a means of sound production. However, as shark biologist Adrian Gutteridge notes, “It’s too early to tell whether it’s a response, kind of saying, ‘go away,’ or if [it’s] just their nervous system firing off which just happens to make their teeth and jaws click” (Live Science, 2024).
This discovery invites us to reflect on the intricacies of God’s creation. Each new scientific breakthrough reveals deeper layers of the natural world, reinforcing our call as stewards of creation. Pope Francis reminds us in Laudato Si’, *”Nature is filled with words of love, but how can we listen to them amid constant noise, interminable and nerve-wracking distractions, or the cult of appearances?”* (Laudato Si’, 225). The more we learn about creation, the more we come to appreciate its divine order and purpose.\n\nWhile further research is needed to fully understand how and why sharks make these sounds, this discovery is yet another reminder of the beauty and complexity of God’s handiwork. By studying nature with a sense of wonder and reverence, we draw closer to the Creator Himself.”
