摘要

A first hand study regarding the anomuran crabs in the intertidal zone of Kadmat and Amini islands of Lakshadweep was carried out during November 2021 to June 2022 by monthly sampling from a total of six sampling stations selected covering the total coastal stretch of Kadmat and Amini islands. The study recorded a total nine species, contributed by eight species of hermit crabs belonging to three genera and two families of superfamily Paguroidea and single species of mole crab of superfamily Hippoidea. The hermit crabs are Coenobita perlatus, Coenobita clypeatus, Calcinus laevimanus, Calcinus latens, Calcinus elegans, Dardanus megistos, Dardanus guttatus and Dardanus deformis. The single species of mole crab is Hippa adactyla. The spatial and temporal variations with respect to abundance and distribution were assessed. The peak average abundance of anomurans was recorded in April and lowest values in December. The northern part of Kadmat Island had the highest total abundance of the anomurans and the east side had the lowest. The most dominant species was Hippa adactyla with maximum records in April. Among hermit crabs the dominant species was C. perlatus, while the least abundant species among anomuran was D. megistos. The distribution and abundance of species differed according to habitat variability. These crabs are used by the local inhabitants of Lakshadweep as bait for fishing, rarely as food and often as a quick remedy for treating cough in children. An interesting traditional use of hermit crab as laxative agent to prevent theft of ‘Neera’. Nowadays unscientific coastal protection structures and other anthropogenic interventions becoming a serious threat to these anomuran crabs.
