The Mitogenome Data of Holothuria (Mertensiothuria) leucospilota (Brandt, 1835) from Malaysia.

The mitogenome of H. leucospilota originating from Sedili Kechil, Kota Tinggi, Johor, Malaysia, is presented here. The size of the mitogenome is 15,982bp which consists of 13 protein coding genes (PCGs), 21 transfer RNAs, and 2 ribosomal RNAs. One gene from tRNA was missing (tRNA-Ile). The putative control region between trnT (ugu) and trnP (ugg) was also not determined due to low coverage and difficulty to assemble and sequenced repetitive DNA region. The overall composition of nucleotide bases was estimated to be 25.8% for T, 25.9% for C, 31.8% for A and 16.5% for G (with A + T content of 57.6%). The mitogenome data of H. leucospilota is available in GenBank database with accession number ON584426.
