The ultrastructure of the digestive gland of several sea hare species that produce different colored ink (Aplysia californicaproduces purple ink,A. julianawhite ink,A. parvulaboth white and purple ink, whileDolabrifera dolabriferaproduces no ink at all) was compared to determine the digestive gland’s role in the diet-derived ink production process. Rhodoplast digestive cells and their digestive vacuoles, the site of digestion of red algal chloroplast (i.e., rhodoplast) inA. californica, were present and had a similar ultrastructure in all four species. Rhodoplast digestive cell vacuoles either contained a whole rhodoplast or fragments of one or were empty. These results suggest that the inability to produce colored ink in some sea hare species is not due to either an absence of appropriate digestive machinery, that is, rhodoplast digestive cells, or an apparent failure of rhodoplast digestive cells to function. These results also propose that the digestive gland structure described herein occurred early in sea hare evolution, at least in the common ancestor to the generaAplysiaandDolabrifera. Our data, however, do not support the hypothesis that the loss of purple inking is a synapomorphy of the white-ink-producing subgenusAplysia.

Sea Hare

Dolabella auricularia are found in the waters of Indo - Pacific and has active compound in health, which until now is still limited information about nutritional content from sea hare. The aim of this research were to determine morphometric and chemical characteristic D. auricularia which includes the proximate, amino acids, fatty acids and minerals. The composition of fatty acid were measured by gas chromatography (GC), amino acids were measured by high performanced liquid chromatography (HPLC), and mineral was measured by atomic absorption spectrophotometer (AAS). The sea hare contained 9 essential amino acids and 6 non essential amino acids. The highest essential amino acid was arginine (1.61%) while the highest non essential amino acids was glycine (3.02%). Sea hare contained 26 fatty acids such as saturated fatty acids 5.33%, monounsaturated fatty acids 2.11% and polyunsaturated fatty acids 4.10%. The high mineral was calcium 68100 mg/kg.
