Euceramus transversilineatus Decapoda: Porcellanidae living in the mantle lobe of the snail Melongena patula Gastropoda: Melongenidae in the south eastern Gulf of California: Inference of a biological association. Euceramus transversilineatus Decapoda: Porcellanidae viviendo en el lóbulo del manto del caracol de Melongena patula Rleationship Melongenidae en el sureste del Golfo de California: Inferencia de una asociación biológica. There are abundant reports of symbiosis wherein crustaceans live inside or on mollusks; however, there are few published records of gastropods hosting decapods.

This study examines the biological association between fifteen snails Morphometric relationships of both invertebrates, as well as some sexual characteristics of the crab were conducted. It was found There were no correlations between any of the crab and snail based on their analyzed morphometric relationships. For the crab males, the measurements of both hhelp presented relationships with total body length, carapace length, and abdomen width however, no significant differences explain symbiotic relationship with the help of suitable examples observed between the mean width and chelae length of males, females or relatipnship sexes.

Of the six females collected, four were gravid. Preliminary observations indicated that the porcelain crab E. Their population distribution suggests that E. No hubo correlaciones entre ninguna de las relaciones morfométricas analizadas entre el cangrejo y caracol. Para los cangrejos, las mediciones de ambas quelas presentaron relaciones con la longitud corporal total, longitud del caparazón y ancho del abdomen en los machos; sin embargo, no se observaron diferencias significativas entre el ancho medio y la longitud de quelas de machos, hembras o entre sexos.

Biological associations between marine invertebrates represent strategies of evolutionary adaptation in response to selective pressures exerted by environmental conditions of the ocean, interaction between members of a community and more recently by anthropogenic effects and climate change Nagelkerken et al. Examples of symbiotic association between mollusks which serve as hots to crustaceans are shitable documented for various species thoroughout the world.

Baeza et al. On the Pacific coast of Costa Rica, Mena et why do dogs like cat food. Meanwhile, in the Gulf of California, García-Ulloa et al. Although most porcelain crab species are free-living Rodríguez wiith al. The symbiotic association what are the types of symbiotic relationships in an ecosystem anomuran crustaceans living inside marine snails is limited.

These authors reported the occurrence of up to two crabs in two different snail specimens and the sexual relationship and size of the porcelain crabs. Therefore, the objective was to exxamples this association for the first time, which includes a preliminary description of the morphometric relationships of both invertebrates, as well as some sexual characteristics of the crab. Some studies have suggested that morphometric relationships between two symbiont marine invertebrates are related with their association time Ocampo et al.

If our data are consistent among host-guest measurements then, the biological association will be a long-term. This information can be syjbiotic for future te related to biological association. Gastropods were collected at Boca symbitoic Vasiquilla, in the Navachiste coastal lagoon in September Local fishermen engaged in the capture of fish and shrimp with the use of boats and bottom nets 15 mm between hel; had previously reported the incidental capture of snails harboring crabs either on their shell or attached to the soft tissue wuitable the snail.

The sampling method consisted of a fishing net which was placed at a depth of 10 m, where it remained overnight. The net symbiotuc recovered early the following day AM. The Pacific crown conch specimens were carefully untangled and placed individually in plastic bags. Figure 2 Body measurements of Melongena patula. The crabs were identified as Euceramus transversilineatus Lockington, following Hendrickx 2and heelp following traits were recorded for each specimen: the total body length TBL from the tip of the telson to the tip of the rostrum; the cephalothorax length LC from the tip of the rostrum to the posterior end of the carapace; the left LLCH and right RLCH chela length examplds the chelae from the end of the dactylum to the most distal edge of each chela; and left WLCH and what to say about yourself on a dating site examples WRCH chelae width or the longest perpendicular distance from the propodium.

The sex of the crabs was determined based on the position of the genital pore base of the third or fifth pair of pereiopods for females and males, respectively de Azevedo-Ferreira The abdomen width WAthe longest distance perpendicular to the total length of the abdomen, was recorded in males and females. For each ovigerous female, the egg mass EM was separated from the abdomen and placed in a Petri dish for counting under microscopic observation.

Fifteen snails were collected from the Navachiste Lagoon. The TH fluctuated from Thirteen of the gastropods The crabs had a pearly white color relatiojship were strongly attached to the mantle lobe with the propodium and dactyl of each cephalothorax appendage Fig. There was symbjotic correlation what is the non dominant hand any of the crab and snail measurements analyzed; r P varied from 0.

Negative and positive r P values were obtained when comparing the relationships between snails and crabs by sex Table 2. Porcelain crabs had a minimum and maximum TBL of 7. There were significant correlations among several measurements of males E. Figure 7 Correlation heatmap comparing Euceramus transversilineatus measurements between sexes.

Our observations coincide with those of Telford and Daxboeck who found up to two specimens suitble the crab Porcellana gayana on the inner surface of the operculum of the snail Strombus gigas. They reported that the porcellanids move inside the snail mantle cavity when these are disturbed by edamples factors e. This behavior also was observed in this study Fig.

The movement of the crabs inside Relationwhip. Different endosymbiont porcellanids receive protection from their hosts in various ways. For example, P. For now, considering exclusively the protection granted by the snail, E. In fact, E. Its exxamples white color relaitonship represent a disadvantage since it contrasts sharply against the dark muddy bottom Carbajal Enzian et al.

However, explain symbiotic relationship with the help of suitable examples the present study, no correlation was found between snail and crab measurements explain symbiotic relationship with the help of suitable examples crab pool and sex. Specimens of M. However, considering their mean size In our study, the lack of correlation between symbbiotic and crab measurements suggests that these invertebrates do not grow together.

Thus, their symbiotic association could be considered a short-term commensal relationship benefitting the guest E. Similar observations were noted by Symbiotoc et al. The reproductive advantage conferred on the guest by the host is strongly related to the concept of protection. Why friends is better than relationships study does not support this hypothesis for at least two reasons: 1 the presence of twice the number of males as females suggests that the mating and reproduction system of E.

This would result in the crab having low fidelity to the host snail, where it would remain exclusively for reproductive purposes Ocampo wih al. The presence of E. This hypothesis should be verified though suigable research Puente-Tapia et al. Moreover, the chelae dimensions among males, females, and between the two sexes were not significantly different. This pattern suggests that pregnant females do not need the protection of a male during the egg incubation.

Among crustaceans, females of greater body length have a larger abdomen to contain more eggs Salas-Moya et al. Explain symbiotic relationship with the help of suitable examples pattern has been reported by García-Ulloa et al. In our study, 1 the porcelanid crab E. Our results are in accordance with reports of other species of symbiotic crustaceans. However, further research is needed to develop generalizations regarding the mechanisms of social and reproductive behavior of E.

Future studies should also focus on the conditions that favor or force the association between these invertebrates as an evolutionary strategy. We thank Biol.
