This study was conducted to determine the cholesterol and alpha-tocopherol contents of 20 marine fish and four other seafood from the Straits of Malacca. Cholesterol and alphatocopherol contents of the fish and other seafood were determined using high-performance liquid chromatography. The results showed that most of the fish contained low amounts of cholesterol, except sixbar grouper (Epinephe...

We recently reported the molecular cloning of nitric oxide synthase (NOS) mRNA from Sepia officinalis (SoNOS) using a strategy that involves hybridization of degenerate PCR primers to highly conserved NOS regions, combined with a RACE procedure. Here, in situ hybridization study has been performed on serial sections of the cuttlefish central nervous system to reveal localized specific staining ...

Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic microsatellite loci...

Figure 1. High-resolution polarisation vision in Sepia plangon improves image contrast. (A) S. plangon responded to looming stimuli that differed in angle of polarisation from the background with an innate deimatic diplay (brightening of body colour). Left portion = pre-stimulus; right portion = post stimulus. (B) Normalized response strength (see Supplemental Information for further details) d...

Stress experienced during prenatal development-either applied to reproducing females (maternal stress), directly to developing offspring (embryonic stress) or in combination-is associated with a range of post-natal behavioral effects in numerous organisms. We conducted an experiment to discern if maternal and embryonic stressors affect the behavior of hatchlings of the cuttlefish Sepia officina...

We report that the skin of cuttlefish, Sepia officinalis, contains opsin transcripts suggesting a possible role of distributed light sensing for dynamic camouflage and signalling. The mRNA coding for opsin from various body regions was amplified and sequenced, and gene expression was detected in fin and ventral skin samples. The amino acid sequence of the opsin polypeptide that these transcript...
