This study compared the chemical compositions of sea cucumbers harvested from the Bndar-elengeh coast in South of Iran July 2011. Their Moisture, ash, protein, and fat contents were measured and recorded. The average protein, moisture, ash, crude fiber and fat were 17.61±.95%, 67.82±3.81%, 32.74±1.17%, 1.87±0.50% and 2.43±0.53% in H.parva and 24.37±1.93%, 69.45±3.09%, 10.86±0.4%, 2.29±0.5% and 2.88±0.47% in H.arenicola respectively. Crude fat and moisture content doesn't show any significant difference (p> 0.05). Significant variations were also observed between protein, ash and crude fiber contents (p<0.05) which ash content in H.parva was more than H.arenicola otherwise protein and crud fiber content in H.arenicola were more than H.pavra(p< 0.05).
