The Ecological Importance of Periclimenes yucatanicus: A Cleaner Prawn Species in Coral Reef Ecosystems

One of the exciting marine invertebrate species that stay inside the waters of the Caribbean Sea and the Gulf of Mexico inside the Western Atlantic is Periclimenes yucatanicus, also called the noticed prawn. This tiny crustacean, that is only 3 cm long, is a member of the distinct reef prawn species, which is well-known for its capability to clean fish residing on coral reefs. 

Cleaner prawns and some small cleaner fishes are essential to the biological stability of small ecosystems because they control and eradicate ectoparasites that infect many fishes' gills, mouths and other external parts, shielding them from disease and lowering stress levels. 

The Fascinating Interspecific Interactions: Reef Fish, Sea Anemones, and Spotted Prawns

Their very existence also influences the fishes' choice of habitat and, consequently, the biodiversity of the entire community. But these species' capacity to form intimate symbiotic partnerships with sea anemones—animals that are closely linked to corals and jellyfish—is what makes their ability to function as cleaners conceivable.

Scientists and aquarium hobbyists alike have been very interested in the Spotted Shrimp because of its unique biological and ecological qualities as well as their stunning colour patterns. We'll look at a few of the more fascinating features of this interspecific system of interactions involving reef fish, sea anemones, and spotted prawns here.

Sea Anemones and Spotted Shrimp Have Symbiotic Relationships

The Spotted Shrimp lives in seas around coral reefs and is often found between one and thirty meters below the surface.Its range in the Caribbean Sea stretches from South Florida to Venezuela, and in the Gulf of Mexico, it has been found on the Yucatán Peninsula and on the reefs of the Campeche Bank.

The Spotted Shrimp's Coexistence with Sea Anemones and Other Coral Reef Species

The Spotted Shrimp has been observed coexisting in coral reefs with a variety of sea anemone species, such as the Branching anemone (Lebrunia neglecta), Pale anemone (Exaiptasia diaphana), Corkscrew anemone (Bartholomea annulata), Giant anemone (Condylactis gigantea) and Atlantic Carpet anemone (Stichodactyla helianthus).

Additionally, it has been seen living side by side with the Upside-down jellyfish (Cassiopea xamachana), the coralimorpharians Rhodactis osculifera and Ricordea florida, and even the Great Star coral (Montastraea cavernosa). It does seem to have a taste for giant anemone and Atlantic carpet anemone, however. Periclimenes yucatanicus and anemones are thought to have a mutualistic symbiotic relationship, meaning that both species gain from it.

The Mutualistic Relationship between the Spotted Shrimp and Sea Anemones: Acclimatization and Benefits

On the one hand, since anemones release harmful compounds, the prawns enjoy the protection they provide against predators. Nematocysts, which are venomous microcapsules with microscopic filamentous spines, are produced by hundreds of cells in sea anemones and other cnidarians. These nematocysts are used by sea anemones to catch food and protect themselves from predators. 

It seems logical to believe that the prawns may be harmed or perhaps killed by these nematocysts. Nevertheless, the prawn develops immunity via a process called acclimatization, so it is unaffected by the nematocysts. During this procedure, the shrimps approach the anemones' tentacles one by one. They may be stung by the nematocysts at first, but as they get acclimated, they learn to move away from the tentacles or migrate towards their base, where the nematocysts' capture reaction is less intense.

The Role of Sea Anemones in the Protection and Distribution of Spotted Shrimp: An Intimate Symbiotic Relationship

The shrimp investigate the tentacles, peck at the mucus-secreting anemones' regions, and it seems that the mucus sticks to their appendages as well. They also seem to consume the mucus. It seems that this mucus is a combination of secretions and expelled nematocysts. The shrimps' tendency to grab tentacles lessens over time, allowing them to roam about the anemone with more freedom. For some species, the observed acclimatization period takes two to five hours. 

The shrimps' degree of protection has been shown to be lost if they are kept apart from their anemones for long periods of time, indicating that their protection is directly tied to their continual engagement with the anemone. Since the shrimp's distribution patterns are dependent on those of the sea anemones, other advantages linked to the shrimp include concealment, stability, and possible range extension. There's a risk that prawn distribution may increase as anemone ranges grow.

The Benefits of the Spotted Shrimp to Sea Anemones: Tissue Cleaning, Parasite Removal, and Nitrogen Contributions

Conversely, the anemones gain from the shrimp's elimination of dead tissue and parasites. Furthermore, zooxanthellae, photosynthetic unicellular endosymbionts, are discovered in many species of anemones that inhabit coral reefs and provide the anemones with oxygen and an alternative electricity supply. 

It's been suggested that this extra nitrogen intake may additionally assist the zooxanthellae residing in the anemone grow and flourish, which might gain the anemone by using giving it extra energy, because the prawns produce nitrogenous waste in the shape of ammonia. which may be available in restricted quantities, the shrimp's little nitrogen contributions might thus be quite significant.

Interaction of Spotted Shrimp with Fishes as a Cleaner Species

For a long while, there was uncertainty about the Spotted shrimp's true status as a cleaner species, despite reports to the contrary practically immediately after it was discovered. Pederson's cleaner shrimp (Ancylomenes pedersoni), a well-known cleaner shrimp species that can be found in the same reefs as P. yucatanicus and even shares almost all of the same host anemone species, has been observed cleaning fish, despite the shrimp's reported almost exclusive presence among the tentacles of symbiotic anemones.

Therefore, despite the fact that some researchers categorized the Spotted Shrimp as a “cleaner or possibly cleaner species,” other researchers argued that there was insufficient data to support the idea that P. yucatanicus displayed such behaviour. It was even suggested that it may have "mimicked" A. pedersoni's cleaning habits in order to increase its food supply or lessen the pressure from predators.

The Spotted Shrimp's Cleaning Behavior: Mutualistic Interactions with Fish and Anemones

It wasn't until a recent study produced convincing field data that showed the Spotted Shrimp successfully engaged in cleaning activity with members of at least nine families of fish, despite some observations suggesting that P. yucatanicus is in fact a cleaner species.

Reef fishes converse with Spotted Shrimp during their cleaning behaviour. The prawn lets the client fish know it's ready for cleaning by waving its long, white antennae. In response, the fish move to within a few centimeters of the anemones and assume mutually beneficial positions, acknowledging the cleaning. 

In this instance, the anemones are also very important because the fish identify the symbiotic shrimps by using them as visual cues and landmarks. Larger anemones have even been suggested to draw in more client fish than smaller ones, presumably because they are easier to spot.

The Spotted Shrimp for Fans of Aquariums

Because of the Spotted shrimp's intriguing forms, color patterns, and biological connections, it has attracted the attention and interest of scientists as well as aquarium aficionados. P. yucatanicus is a well-liked and sought-after species in marine aquariums because of its propensity to interact and coexist with sea anemones. It is crucial to remember, nevertheless, that not every kind of sea anemone is appropriate for developing this bond with cleaner shrimps.

It takes careful consideration and the selection of appropriate sea anemone species to preserve this symbiotic interaction in a lab setting. The Spotted Shrimp and all the anemone species with which it coexists symbiotically inhabit habitats linked to coral reefs, suggesting that they are acclimated to shallow, warm, and transparent waters. 

It is essential to take into account that cleaner shrimps require an acclimation period to adjust to the new environment and prevent potential harm, in addition to appropriately replicating the conditions of the natural environment in the aquarium to support the establishment and maintenance of this symbiotic relationship.

It is crucial to emphasise that purchasing cleaner prawns and sea anemones should be done in an ethical and responsible manner. Marine ecosystems may suffer as a result of the harmful collection of some sea anemone species from the wild. As a result, it is advised to purchase these species from trustworthy vendors that, if at all feasible, raise them in captivity in an environmentally friendly manner.
