Metal ion content in Sepia officinalis melanin
Marine Chemistry, 1992Abstract A dissolution procedure for the analysis of the metal content in Sepia officinalis melanin has been optimized and checked against a bovine liver Community Bureau of Reference (BCR) certified reference material. The content of several metal ions has been determined by GF-AAS and ICP-AES techniques in samples of Sepia officinalis melanin ...

Allometry of thermal limitation in the cephalopod Sepia officinalis
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007Cuttlefish (Sepia officinalis) routine metabolic rate was determined in response to acute thermal changes at a rate of 1 degrees C h(-1) for a variety of animal sizes (15-496 g wet mass, laboratory reared at 15 degrees C). In a thermal frame of 11 to 23 degrees C, oxygen consumption rates (MO(2), in mumol O(2) g(-1) min(-1)) were observed to rise with ...

The Influence of Photoperiodicity on Hatching ofSepia Officinalis
Journal of the Marine Biological Association of the United Kingdom, 1991The influence of photoperiodicity on hatching ofSepia officinaliswas investigated under different experimental light-dark (LD) conditions. The results are viewed in relation to some relevant properties of the perivitelline fluid (PVF) and the egg capsule during embryonic development. In embryos ofS. officinalisthe transition from light to dark ap-pears

The English Channel population of the common cuttlefish Sepia officinalis is the northernmost stock among the entire family Sepiidae. It is characterized by the largest eggs among the species (8.5–12.2 mm in length and 221–533 mg in weight).

Sign tracking in cuttlefish (Sepia officinalis).
Journal of Comparative Psychology, 1999Two groups of cuttlefish (Sepia officinalis) were used to demonstrate classical conditioning in this species and to determine whether the resulting approach response would be that of sign tracking or goal tracking. For cuttlefish in the paired condition, a flashing light was presented at one end of a long tank followed by food dropped into the center ...

Melanogenesis in the Ink Gland of Sepia officinalis
Pigment Cell Research, 2003Among the various melanin‐producing systems, the ink gland of the cuttlefish (Sepia officinalis) has traditionally been regarded as a most convenient model system for the studies of melanogenesis. The ink gland is a highly specialized organ with immature cells in the inner portion, from where the cells gradually mature, migrate towards the outer ...

Superoxide dismutase in Sepia officinalis L.
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1981Abstract 1. 1. Fractionation of a crude banchial gland extract of Sepia officinalis L. on a ACA-22 column resulted in five protein fractions. The presence of superoxide dismutase (SOD) was established in three of them (P3, P4 and P5). The bulk of the SOD activity was present in fraction P4. 2. 2. The enzyme was temperature sensitive.
