According to scientific studies, certain fish species have adaptations that allow them to navigate and withstand the challenges posed by internal waves in seawater. Internal waves are large-scale waves that occur within the water column, typically at the interface between water layers of different densities.
One notable example is the Pacific bluefin tuna (Thunnus orientalis). These large and highly migratory fish are known to be capable of crossing internal waves. They possess a streamlined body shape, powerful muscles, and an efficient swimming mechanism that enables them to navigate through turbulent waters.
Another example is the Atlantic cod (Gadus morhua). This species is found in the North Atlantic Ocean and has been observed to withstand and traverse internal waves. Cod have a robust and muscular body, which helps them navigate through turbulent waters.
Additionally, some studies suggest that certain species of sharks, such as the great white shark (Carcharodon carcharias) and the porbeagle shark (Lamna nasus), may also possess adaptations that allow them to cross internal waves. These adaptations could include efficient swimming capabilities and an ability to detect and navigate through turbulent waters.
It's important to note that the ability to cross internal waves is likely influenced by a combination of factors, including the fish's physical characteristics, swimming abilities, and behavioral adaptations. While these fish species have been observed crossing internal waves, further research is necessary to fully understand the extent of their capabilities and the mechanisms involved.
