Abstract

1. 1. The absorption efficiency for E. thouarsii fed P. damicornis is 44.7% for carbohydrate, 85.3% for protein and 69.3% for lipid. 2. 2. E. thouarsii fed P. damicornis absorbs 0.402 mg carbohydrate, 2.814 mg protein and 1.108 mg lipid for each g of P. damicornis ingested. 3. 3. E. thouarsii fed P. damicornis absorbs 0.201 mg carbohydrate, 1.407 mg protein and 0.554 mg lipid per individual per day. 4. 4. E. thouarsii fed P. damicornis absorbs 0.824 × 10-3 kcal carbohydrate, 7.950 × 10-3 kcal protein and 5. 5.235 × 10-3 kcal lipid per individual per day. 6. 5. Despite the high efficiency of digestive absorprion of organic constituents of the coral ingested, E. thouarsii must consume large quantities to meet its nutritional requirements.
