A fascinating new discovery in the world of coral biology has shed light on the intriguing behavior of mushroom corals. These solitary creatures, belonging to the Fungiidae family, have been observed exhibiting a unique form of movement that researchers are calling a “walk.”
Coral biologist Brett Lewis and his team captured this mesmerizing movement through time-lapse photography. While the term “walk” may not accurately describe the motion of these coral polyps, they do indeed appear to “pulse and inflate like a jellyfish” to propel themselves forward. This subtle hopping action allows the corals to navigate their surroundings and find new locations to settle.
Despite their solitary nature, mushroom corals are not to be underestimated. Their bodies are covered in a sticky biofilm that traps unsuspecting prey, which is then drawn towards their multiple mouths for consumption. These mouths lead to a stomach filled with wormy filaments equipped with stinging and digestive cells, enabling the corals to feed on a variety of small creatures.
One of the most striking features of mushroom corals is their ability to move their entire body. Starting life on a reef, these corals eventually relocate to sandy, deeper ocean bottoms to establish a permanent home. This migration involves a slow and steady process of inflation and pulsation, allowing the corals to “hop” their way to a new location.
Through advanced imaging techniques, researchers have been able to capture the intricate movements of these corals in unprecedented detail. The corals puff up their dome-shaped bodies, making contact with the bottom before bouncing off in a series of micro-hops. This methodical process of inflation and movement allows the corals to cover significant distances over time.
Interestingly, the color of light filtering through the water plays a crucial role in guiding coral movement. Corals have been observed to gravitate towards bluer wavelengths, which penetrate deeper into the ocean. By manipulating the intensity of blue light in laboratory settings, researchers have been able to influence the direction in which corals move, hinting at a complex relationship between light and coral behavior.
Overall, the discovery of the “walking” mushroom corals opens up new avenues for understanding the behavior and adaptation of these enigmatic creatures. As researchers delve deeper into the mysteries of coral biology, they continue to uncover the remarkable capabilities of these seemingly simple organisms.
