AbstractMale and female Uca tangeri (the only fiddler crab species to inhabit Europe) construct mudballs from mud excavated from within their burrows. Individual males placed similar patterns of mudballs each low tide, suggesting that there is some degree of stereotypy. When mudballs were experimentally moved further from the burrow or closer to it, males only repositioned those that were moved closer, placing them further away again. However, males did not replace mudballs that had been experimentally destroyed at the end of the mudballing phase when they had started to court females. In binary presentation tests, females showed no significant differences in response to mudballs made from different types of mud, or different numbers of mudballs. These results are consistent with earlier findings that male mudballs function as territory boundaries. However, we provide evidence that male mudballs have no function in female attraction, contrasting with previous studies.

The fiddler crab is also known as the kepiting biola is an animal that has broad legs that belong to the Crustacean class. Fiddler crab is a type of crab that has a habitat in intertidal areas, especially around mangrove forests and sandy beaches. This study aims to examine the identification of fiddler crab species found in the Mangrove Sebubus. The method used in this research is purposive sampling method with the use of a square plot size of 1 x 1 meter as many as 30 pieces in 3 research lines. The results showed as many as 7 species of fiddler crabs found there, that is Uca annulipes, Uca rosea, Uca forcipata, Uca bellator, Uca tetragonon, Uca paradussumieri, and Uca acuta.Keywords: Identification, Fiddler Crab, Mangrove Sebubus

Do mudballs around burrows affect burrow characteristics of the fiddler crab Austruca annulipes (H. Milne Edwards, 1837) (Brachyura, Ocypodidae)?

We examined the effects of mudballs around burrows and of sex on burrow characteristics (shape, diameter, length, depth and volume) in an underground mating fiddler crab species,Austruca annulipes(H. Milne Edwards, 1837). We investigated 35 burrows with mudballs (males: 20; females: 15) and 34 burrows without mudballs (males: 16; females: 18), and measured their burrow characteristics. Results showed that burrow characteristics did not differ between burrows with and without mudballs. Males built larger-sized burrows with greater volumes, and had more mudballs than females. Crabs built J-, I-, L-, S- and U-shaped burrows, with higher numbers of J-shaped burrows in males, and higher numbers of I-shaped burrows in females. J-shaped burrows were larger with greater volumes, and had more mudballs than I-shaped burrows. For burrows with mudballs, mudball numbers were positively associated with burrow characteristics. This indicates that fiddler crab burrow characteristics are affected by sex, not by the production and presence of mudballs.
