November 16, Views1Comment Sea anemone tentacles are capable of delivering a toxic sting, which can paralyze not only small fish, but larger marine It is not only the clownfish that benefit from this symbiotic relationship. Symbiosis is any type of a close and long-term biological interaction between two different Mycorrhizas; Pollination; Acacia ants and acacias. 10 See also An example of mutualism is the relationship between the ocellaris clownfish that dwell among the tentacles of Ritteri sea anemones. The territorial. 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.

Examples of metabiosis are hermit crabs using gastropod shells to protect their bodies, and spiders building their webs on plants. Parasitism Head scolex of tapeworm Taenia solium is adapted to parasitism with hooks and suckers to attach to its host. In a parasitic relationshipthe parasite benefits while the host is harmed.

Parasitism is an extremely successful mode of life; as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi. Moreover, almost all free-living animal species are hosts to parasites, often of more than one species. Mimicry Mimicry is a form of symbiosis in which a species adopts distinct characteristics of another species to alter its relationship dynamic with the species being mimicked, to its own advantage.

Batesian mimicry is an exploitative three-party interaction where one species, the mimic, has evolved to mimic another, the model, to deceive a third, the dupe.

In terms of signalling theorythe mimic and model have evolved to send a signal; the dupe has evolved to receive it from the model. This is to the advantage of the mimic but to the detriment of both the model, whose protective signals are effectively weakened, and of the dupe, which is deprived of an edible prey.

For example, a wasp is a strongly-defended model, which signals with its conspicuous black and yellow coloration that it is an unprofitable prey to predators such as birds which hunt by sight; many hoverflies are Batesian mimics of wasps, and any bird that avoids these hoverflies is a dupe. Amensalism is an asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other.

Competition is where a larger or stronger organism deprives a smaller or weaker one from a resource. 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.

Spawning generally occurs around the time of full moon. The male is known to guard the eggs until they hatch after days. They lay eggs ranging from hundreds to thousands.

They are the first known fishes to breed in captivity. The average life span is of years but in captivity they live up to years.

They show a special association with the sea anemone. The activity of these fishes result in greater amount of water circulation around the sea anemone and sea anemone provides them protection from its toxins.

Clownfish depends on the sea anemone for its daily food. When anemone paralyzes a fish and consumes it these fish eat the chunks and pieces left after the feeding of the anemone. The fish also keeps the anemone free by eating up its dead tentacles and act as a lure by attracting predators towards itself by its bright colouration.

This sort of symbiotic association of the clownfish with the sea anemone makes them the most astonishing creatures living under water. They are known bred in captivity in the marine ornamental farms in USA.

Clownfish and Sea Anemones

If the anemone of the aquarium dies they tend to live in the soft varieties of corals. The corals may agitate the skin of these fishes and in some cases may kill the corals also.
