Pacific Blenny Research Paper

The Pacific leaping blenny is a small fish found on the tropical island of Guam. Its scientific name is Alticus arnoldorum and it has made one of the most tremendous ecological transitions over time. The Pacific leaping blenny effectively established its population on land through an evolved variety of adaptations, such as: the ability to move efficiently on land and being able to perform respiration through its skin while still relying on its gills. The fish are limited to the “splash zones” of the intertidal areas around the island of Guam, so that they can avoid desiccation. The fish, however, seemed to be terrestrial and would almost never return to the water. The fish spend most of their time feeding on rocks and other areas that are out of the water. Scientists are interested in studying the Pacific leaping blenny because it is a …show more content…
I believe that the various color differences of the Pacific leaping blennies are selected naturally to go with the background of their environments. I believe that this is only way the blennies can defend themselves against the variety of predators in the different habitats. I also agree that the Pacific leaping blennies can only inhabit environments that contain a lot of predators if they have a successful approach to handle the predators. I agree with this statement because if the blennies’ approach to the predators was not successful then they would not be able to efficiently inhabit the areas in which they desire to live. Lastly, I agree that another way for the fish to survive in an area with predator infestation is if they are able to go through fast changes in their phenotypes that could potentially decrease contact with predators. The Pacific leaping blenny has already made outstanding ecological transitions, so therefore adaptations such as varying body coloration would not be difficult for
