cleaner wrasse and grouper fish relationship site

One of the most striking examples of symbiosis involves the cleaner wrasse. This fish is responsible for setting up what are known as "cleaning stations,". Jan 4, The introduction of Labroides spp. cleaner wrasses to marine aquarium Labroides wrasses do pick certain ectoparasites off fish, but After observing a cleaner wrasse attending to a large predatory species, such as a grouper or Again, you have to keep in mind that the cleaner/client relationship in the. This Symbiotic Relationship between the Cleaner Wrasse and the other fish is on many reef fish (parrotfish, reef sharks, moray eels, groupers, damsel fish.

Data from all sites were pooled due to non-significant differences in cleaning rates from ANOVA analyses. Results Cleaner fish behaviour Cleaner fish were observed at all sites combined for one-minute periods. Individuals were observed inspecting clients Groupers were the subject being inspected 5. Four grouper species were observed as clients: There were also no significant differences in the mean time cleaning fish inspected grouper clients among the observers, habitat types or sites Figure 1B.

Discussion This study examined the amount of time cleaner wrasse Labroides dimidiatus Valenciennes, spent cleaning grouper species in the Maldives and found that grouper are an important client. Grouper were clients Habitat and depth did not affect overall cleaning rates or cleaning rates when grouper were clients at our study sites.

The cleaner wrasse Labroides dimidiatus Valenciennes, spent Overall cleaning rates for grouper was 5. Of those fish cleaned, A Labroides dimidiatus cleaning rate mean observations per one minute period, maximum of 7 fish was observed inspecting or cleaning a client among three reef slope habitat types.

In contrast, Sluka examined six grouper species and found cleaner wrasse L. Grouper also feature as more prominent clients in several studies conducted in the Caribbean region.

5 Cleaner Wrasse Myths

One tiger grouper Mycteroperca tigris Valenciennes, was observed cleaning in one event for 45 minutes. Sluka and Sullivan found that coney Cephalopholis fulva Linnaeus, and Nassau grouper Epinephelus striatus Bloch, spent 7. In contrast, Potts did not record any grouper among the top ten most cleaned client species; in several of his experiments, grouper were These same factors are also an important influence on grouper cleaning ecology.

Sluka examined the activity patterns of six grouper species. There were significant differences in the amount of time spent cleaning among species. Sluka and Sullivan showed inter and intra-specific variability in cleaning rates between coney Cephalopholis fulva Linnaeus, and Nassau grouper Epinephelus striatus Bloch, Differences in cleaning rate may be most significantly related to size differences within and among grouper species.

Size has been shown to be related to cleaning rate for many client species. Grutter showed that cleaner wrasse L.

Larger client species are also found more often near cleaning stations than smaller species Poulin Smaller cm TL graysby C. However, Sluka found no correlative evidence between cleanign rates and fish size either within or among species. Given the size range of grouper available for study maximum TL 20 cm and the importance of cleaning stations to grouper distribution, this subfamily may be an excellent choice for examining this question further. For example, graysby C. Amongst studies where data is available for grouper, there appears to be cleaner-client preferences.

Wicksten ; examined how often five cleaning organisms three fish and two shrimp cleaned grouper. The percentages differed between the two studies, but gobies Elacatinus sp.

Whiteman and Cote also showed differences in the percent of visits grouper made to cleaning stations between two goby species. Data is lacking to make firm conclusions, but it suggests that groupers have preferences for certain cleaning organisms. Whether this is of a general nature i. Evidence supporting the conclusion that the grouper-cleaner relationship is species-specific comes from a feeding experiment where juvenile bluehead wrasse Thalassoma bifasciatum which does not clean as an adult, and cleaner gobies where introduced into tanks containing various species of grouper.

No grouper species ate the gobies, while red hind E. No inter-habitat differences in cleaning behavior were found in this study. However, habitats examined were all reef slopes with differing geo-morphological and biological features and may not have exhibited enough differences to influence cleaner behavior. Grouper assemblages are significantly different among these habitats Sluka,but these differences do not result in differing cleaning rates.

Other studies which have examined coral reef habitats with more significant differences e. Grouper distribution, density, and species diversity generally varies among habitats at several spatial scales Sluka et al. In an experimental study in the Bahamas, Sluka et al. Removal of the cleaning station resulted in groupers leaving the reef more often than prior to the removal, presumably to seek other cleaning opportunities.

However, among coral reefs, grouper density was not correlated to cleaning station or cleaner density Sluka et al. Grutter showed a similar result where the removal of cleaner fish did not result in a change in grouper abundance.

But see Grutter et al. Grutter's study did not consider possible movement off the reef to seek other cleaning opportunities. A large, mobile parrotfish, the longnose parrotfish Hipposcarus harid Forsskal, was recently shown to move to other cleaner stations in response to a lack of cleaning opportunity Bshary and Schaeffer, It appears that locally, cleaning stations are a significant aspect of grouper habitat.

But the grouper's ability to move and potentially find other cleaning opportunities seems to obscure any effect of cleaning station or cleaner density on large-scale grouper abundance patterns. Future research could benefit by using similar approach as previous studies conducted on smaller, less mobile client fish to determine the universality of those conclusions. Especially examining the effect of mobility and size within and among grouper species on cleaner-client relationship.

Cleaner fish

Numerous questions remain as to the ecological significance of cleaners or cleaning stations to grouper ecology as well as the significance of groupers to cleaners. It is clear that studies which have specifically focused on grouper-cleaner relationships have shown the importance of this interaction to both cleaner and client.

Cleaning stations should be considered an important part of grouper habitat. Acknowledgements Thanks to Mr. Yoosuf Nishar and Mr. Abudullah Hakeem, who assisted in all aspects of the field work. Ahmed Shakeel and Ms. Special thanks to A.

It's clear that these fish have one thing on their mind when they line up at the cleaning station: Easily distinguished by a bright blue and yellow band, the cleaner wrasse makes an effort to advertise its services by performing a dance.

Likewise, when a fish wants to be "cleaned" it sends specific signals to the wrasse, such as keeping its body stationary, while spreading its fins and gills and opening its mouth.

If the wrasse picks up on the signal it will begin the cleaning process on its customer, which is usually a larger fish. Cleaning consists of the wrasse swimming over the entire body of its customer, eating parasites from the fins and gills.

The wrasse will even go inside the mouth and clean between the teeth of its customer. Interestingly enough, the wrasse is rarely injured or eaten by the other fish; the wrasse vibrates its fins while cleaning to remind its customer of its presence. Moreover, the cleaned animal will frequently defend the cleaning station and its cleaners from attack by would-be predators. Almost all marine species are actively involved in close symbiotic relationships with at least one other species in their community.

The unique relationship between the cleaner wrasse and the fish it cleans at the "cleaning stations" are an important and impressive example of symbiosis. Not only does the satisfied customer leave parasite free, but also the wrasse enjoys a protein rich meal.
