Thenus unimaculatus or a purplelegged shovel-nosed lobster is one of the three species found in Thailand. Shovelnosed lobsters have been increasingly consumed and this could give great threat to T. Unimaculatus. This has narrow range distribution, only Andaman Sea. Genetic diversity study purple-legged therefore needed for evaluating its current genetic status. In study, 71 specimens were collected from five provinces along Sea coastline. 12S ribosomal RNA (12S rRNA) cytochrome C oxidase subunit I (COI) mitochondrial genes PCR amplified. The rDNA COI nucleotide sequence alignments 60 70 samples, respectively, successfully prepared, suggesting that parsimony informative sites gene was higher than rDNA. Phylogenetic analysis using Maximum Likelihood method revealed populations Thailand are fairly homogenised. blended among provincial indicates there circulation planktonic larvae, resulting two different patterns sea currents
