If you've seen the film 'Finding Nemo', you may already be familiar with clownfish and sea anemones. But, do you understand why they can live. Clownfish (Amphiprion ocellaris) are colorful fish that has its habitat in Clownfish have a symbiotic relationship with anemones. Plush Clown Fish (1 dz) . are the warm waters around the coral reefs of the Coral Triangle and the Red Sea. vestigated the mutualistic relationship between clownfish and sea anemones. Our initial goal Populations with rac and r2c approaching 1.

Majority of the species are known to dwell in restricted areas while others have a wide range of distribution.

Mutualism with sea anemones triggered the adaptive radiation of clownfishes

They are generally host specific but some species also show coordination with other species also. They are known to dwell at the bottom of the sea floor confined in the shelters of lagoons or coral reefs.

They prefer to live in pairs. They are also distributed in the northwest Australia, Southeast Asia, Japan and the Indo-Malaysian region but totally absent in the Caribbean region. They are known to feed on small invertebrates otherwise they may cause damage to the sea anemone. The faecal matter released by these fishes act as source of nutrients for the sea anemone. The diet comprises of copepods, algae, zooplanktons and algae. They also feed on small crustaceans and molluscs.

When kept under captivity they are provided fish pellets and fish flakes and food. They also feed on the undigested food material of the sea anemones. Clownfish and certain damselfish are the only known species of fishes which are able to remain unaffected by the poison secreted by the sea anemone.

Clownfish and its mutualism relationship with anemones

Many theories have been put forward to support this view. According to one view the mucus coating of the fish may be composed of sugars rather than proteins so the sea anemone fails to recognize the fish as food sources and does not attacks it.

Another view suggests that due to co-evolution clownfish has developed immunity against the toxins secreted by the sea anemone. It is well known that they tend to live in pairs in a single anemone and when the female dies the male changes its sex to female.

This process is known as sequential hermaphroditism. Clownfish are born as males and that is why they are protandrous hermaphrodites. On top of the hierarchy reproducing female is present followed by the male but if the female dies this hierarchy gets disrupted. The largest member of a group is a female and the second largest one the male. Clownfish are neuter which means that they do not have fully developed sex organs for either gender.

Clownfish prefer to lay their eggs on flat surfaces where they can adhere properly.

Investigation

This means they benefit from living with the sea anemone, and the sea anemone benefits from the presence of the clownfish. They are the only fish that are able to live in sea anemones and not get stung by their tentacles. Clownfish are very active fish and are extremely aggressive. Because they are quite active, the clownfish are thought to be "clowning around".

They defend their territory and the sea anemone that they live in. Clownfish eat the leftovers from fish on the anemone and algae. The leftovers include copepods, isopods and zooplankton.

Clownfish have a few ocean predators, but their greatest threat is humans.

People who catch clownfish and keep them as pets in aquariums are making a mistake. There are only ten out of more than one thousand types of anemone that are able to host these fish.

Many people put the fish in a tank with the wrong anemone. In captivity, the clownfish can live from 3 to 5 years. In the wild, they live 6 to 10 years. Symbiosis describes the special relationship between clownfish and sea anemones. They are the only fish that do not get stung by the tentacles of the sea anemone. Clownfish have a slimy mucus covering that protects them from the sea anemone.

However, if this covering is wiped off of a clownfish, it will get stung and possibly be killed when it returns home to the anemone. The clownfish and the sea anemone help each other survive in the ocean.

The clownfish, while being provided with food, cleans away fish and algae leftovers from the anemone.

In addition, the sea anemones are given better water circulation because the clownfish fan their fins while swimming about. Clownfish live at the bottom of the sea in sheltered reefs or in shallow lagoons, usually in pairs.

Clownfish have a special relationship with the anemone and are very important to them. They are a large help to the anemone as they clean the anemone by eating the algae and other food leftovers on them. They also protect the sea anemones by chasing away polyp-eating fish, such as the butterfly fish.

The map below shows where in the world clownfish can be found. They live in the warmer waters of the Pacific Ocean and Indian Ocean. There are no clownfish in the Caribbean.
