Common clownfish (Amphiprion ocellaris) is also called clown anemone fish, false clownfish, or false percula. It is a species of anemone fish best known for its striking orange and white coloration and its mutualism with certain species of sea anemones. The common clown fish is found on coral reefs in the tropical Pacific and Indian oceans from northwestern Australia, Southeast Asia, and Indonesia. The species achieved popular recognition through its depiction in the animated feature film Finding Nemo (2003). The orange coloration on the body is broken up by three white bands with thin black borders. Most individuals also have 11 dorsal fin spines, a characteristic that often is used to distinguish the species from the orange clown anemone fish (Amphiprion percula), which is nearly identical. The common clown fish also has a muddy brown ring around the pupil of the eye, whereas the ring in the pupil of the orange clown anemone fish is clear. Common clownfish can grow to 11 cm in length. The diet of the common clownfish is largely made up of algae and small invertebrates such as zooplankton and marine isopods.  However, parts of organisms killed by the host anemone are also consumed. Clownfish breeding takes place throughout the year. It begins when a female lays between 100 and 1,000 eggs. To deposit the eggs, the female drags her ovipositor over the substrate of a nest made clean earlier by the breeding male. The nest may occur within a sea anemone or on a nearby rock protected by a sea anemone’s overhanging tentacles. After the breeding male fertilizes the eggs, both parents guard them until they hatch some 8–12 days later. Parental care ceases at this time, and the young float away on ocean currents. At sea, many of the young are eaten by various predators. However, after approximately two weeks, surviving young begin to explore nearby coral reefs for an appropriate sea anemone host. Survival of the common clown fish depends on mutualism with sea anemones. The anemone’s tentacles, which contain numerous stinging cells that are used to immobilize the anemone’s prey, protect the common clownfish from its predators. In return, the fish cleans parasites from the anemone’s body and prevents butterfly fishes from consuming the anemone’s tentacles. (Adapted from: www.britannica.com.

Jawaban

jawaban yang benar adalah D. Pada paragraf terakhir dijelaskan bahwa common clownfish mengandalkan anemone untuk bertahan hidup dari predator.

Pembahasan

Pilihan A salah karena pada paragraf terakhir dijelaskan bahwa clownfish justru membersihkan tentakel anemone dari parasit. Pilihan B salah. Pada paragraf keempat dijelaskan bahwa banyak telur yang bisa dihasilkan clownfish adalah 100 sampai 1000, tidak lebih dari 1000. Pilihan C salah karena yang memiliki tentakel adalah anemonenya. Pilihan E salah karena common clownfish terlihat hampir sama/mirip dengan orange clown anemone fish. Hampir mirip/sama berarti masih ada perbedaan. Jadi, jawaban yang benar adalah D. Pada paragraf terakhir dijelaskan bahwa common clownfish mengandalkan anemone untuk bertahan hidup dari predator.
