Marine Fish Essay

1279 words - 5 pages

There are vast ranges of beautiful marine and salt water organisms. The array of colors, behaviors, adaptations, and symbiosis are unique to each species. The Amphiprion percula, known as the True Clown Anemonefish, is distinctive for its symbiotic relationship with anemones and as a protoandrous sequential hermaphrodite. The percula clownfish is merely one of 28 known species of anemonefish that has a symbiotic relationship with 10 species of anemones (Elliott, 1997). The clown anemonefish (Amphiprion percula) is a familiar study species in the marine biology field due to its distinguishing characteristics. It is perhaps the most common and well-known of the genus Amphiprion. However, it is readily mistaken for Amphiprion oscellaris, the False Percula Clown Anemonefish, in which the only difference lies in the number of dorsal spines. The true Percula clown may possess nine to ten dorsal spines, while the False Percula Clown will have eleven. As a member of the kingdom Animalia within the phylum Chordata, the percula clownfish is in the family Pomacentridae within the Actinopterygiian class. As a relative of the damselfish, the percula clownfish is easily identified, as it was popularized by the Disney film, “Finding Nemo”. A. percula can grow up to 13 cm in length and is often distinguished by three white vertical bars on a bright orange body that are bordered by black lines; the anterior white bar behind the eye, the middle projecting bar bisects the fish, and the posterior bar occurs near the caudal fin (Lee, 2003). The marine fish possesses an omnivorous diet; it feeds on zooplankton such as copepods and larval tunicates, algae from neighboring coral reefs, leftover food from its host anemones, as well as small crustaceans.A. percula is found within the tropical waters of the Pacific Ocean, Indian Ocean, the Red Sea, and the Great Barrier Reef. The region of Madang, Papua New Guinea, has the highest reported species diversity of both anemonefishes (nine species) and their host anemones (ten species) (Elliott, 2001). A. percula are non-migratory species and live at depths ranging from 3 to 49 feet (1 to 15 m). It rarely exceeds 12 meters and A. percula exist in waters ranging in temperatures from 25-28 degrees Celsius (Randall et al., 1997). A unique adaptation of the percula clownfish is a special symbiotic relationship with sea anemones. It uses its host anemones for shelter and protection from its predators of damselfish and wrasses, and brittlestars against their fish larval eggs. More specifically, Amphiprion percula forms symbiotic associations with the anemones Stichodactyla mertensii, Heteractis magnifca (in outer reefs), and Stichodactyla gigantea (on shore reefs). The percula clownfish and its respective host sea anemone both benefit from the symbiotic relationship (mutualism). In exchange for shelter and protection, Amphiprion percula may feed (by storing food within the sea anemone), oxygenate, and remove waste material...

With the new techniques of locating the fish, and the larger amount of the commercial fishing, ninety percent of the world’s fish and seafood have been depleted in the past century. If we cannot know how much fish remains in the ocean and reduced our amount of catching, one day all the fish would be gone. And at that time, human would be hard to

Achieving Ionic Equilitbrium In Marine Fish

771 words - 4 pages Marine fish sustain an ionic equilibrium with seawater to keep their plasma around 350 mOsm/kg. The gills remove excess salts from the body (Evans et al., 2005), a process that indirectly causes water loss driven by the dehydrating effect of salinity. Therefore, water replacement by drinking becomes of absolute importance to sustain ion regulation (Fuentes and Eddy, 1997a). In addition to regulation by endocrine and environmental factors of the
