The present study was carried out to compare the seasonal variability of Laurencia species in Tirunelveli region, the south east coast of Tamil Nadu, India. For the collection and estimation of Laurencia species, Tirunelveli region was divided in to four stations namely Kootapuzhi, Perumanal, Idinthakarai and Koothankuzhi. Monthly survey was conducted regularly for a period of four years from January 2007 to December 2010. The Laurencia species were enumerated at random using a quadrate (0.5m2 ). A total of four species of Laurencia were collected in the study area such as Laurencia flagellifera, Laurencia obtusa, Laurencia pinnatifida and Laurencia poiteaui. The frequency and density were calculated and all the Laurencia species showed a similar pattern of seasonal variation. Among the species collected the highest frequency (45.00%) and density (2.25) were observed in Laurencia pinnatifida during monsoon season and the lowest frequency (20.00%) and density (0.96) were recorded in Laurencia obtusa during pre-monsoon season. All the Laurencia species were disappeared during the summer season. From the present study, it was concluded that all the Laurencia species (Rhodophyceae) exhibited the maximum frequency and density during the monsoon season followed by the declined trend was observed in the post-monsoon season. During the summer season all the Laurencia were disappeared followed by the frequency and density of Laurencia species (Rhodophyceae) was minimum during the pre-monsoon season in the selected Tirunelveli region in south east coast of Tamil Nadu, India.
