Males And Females

In fiddler crabs both males and females defend territories that are essential for survival. Given pronounced sexual dimorphism in weaponry, how do weaponless females defend their territory from well-armed males? Using observational data and two simple experiments, we test whether male Uca annulipes protect their female neighbours from conspecific intruders. We show that males defend their female neighbours against male but not female intruders. We also show that females sometimes mate with their immediate neighbours. Male defence of female neighbours appears to represent both pre-copulatory mate-guarding and a territorial coalition. Males who ensure that their neighbour remains female could benefit through increased opportunity for future reproductive success and lower boundary maintenance costs.

Uca Annulipes

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
