Abstract

Echinoderms of Had Khanom – Mo Ko Thale Tai National Park, Nakhon Si Thammarat Province, located in the southern part of the Gulf of Thailand were studied at 12 sites namely, Ko Tan (4 sties), Ko Mudsum (2 sites), Ko Wang Nai (2 sites), Ko Wang Nok (2 sites) and Ko Rab (2 sites) in November, 2006 and May 2008. The investigations were carried out by SCUBA diving in the daytime and random searching throughout the reefs. The results yielded 24 species of Echinoderms from 5 classes, 10 orders, 14 families and 20 genera. The most abundant echinoderms in the study area are: Lamprometra palmata, Ophiothrix (Ophiothrix) exigua, Holothuria (Metensiothuria) leucospilota, and Diadema setosum. All observed species were commonly found in the Gulf of Thailand and the Indo-Pacific.
