Accommodation in the cuttlefish (Sepia officinalis).
We have studied natural accommodation in the eye of six specimens of cuttlefish (Sepia officinalis) as they were fed with fish and shrimp. Using infrared photoretinoscopy, we observed (1) that the resting refractive state of the cuttlefish was emmetropic or slightly hyperopic, (2) that accommodation took place only a fraction of a second before a strike and (3) that accommodation focused select...
متن کاملCamouflage during movement in the European cuttlefish (Sepia officinalis).
A moving object is considered conspicuous because of the movement itself. When moving from one background to another, even dynamic camouflage experts such as cephalopods should sacrifice their extraordinary camouflage. Therefore, minimizing detection at this stage is crucial and highly beneficial. In this study, we describe a background-matching mechanism during movement, which aids the cuttlef...
متن کاملThe rhodopsin gene of the cuttlefish Sepia officinalis: sequence and spectral tuning.
The cephalopod molluscs are a group of invertebrates that occupy a wide range of oceanic photic environments. They are an ideal group of animals, therefore, in which to study the evolution of rhodopsin. The cDNA sequence of the rhodopsin gene of the cuttlefish Sepia officinalis (L.) (Sub-class Coleoidea, Order Sepiida) is presented, together with an analysis of the structure of the gene. A prol...
متن کاملSymmetrical crypsis and asymmetrical signalling in the cuttlefish Sepia officinalis.
The salience of bilateral symmetry to humans has led to the suggestion that camouflage may be enhanced in asymmetrical patterns. However, the importance of bilateral symmetry in visual signals (and overall morphology) may constrain the evolution of asymmetrical camouflage, resulting in the bilaterally symmetrical cryptic patterns that we see throughout the animal kingdom. This study investigate...
متن کاملMitochondrial dynamics underlying thermal plasticity of cuttlefish (Sepia officinalis) hearts.
In the eurythermal cuttlefish Sepia officinalis, performance depends on hearts that ensure systemic oxygen supply over a broad range of temperatures. We therefore aimed to identify adjustments in energetic cardiac capacity and underlying mitochondrial function supporting thermal acclimation and adaptation that could be crucial for the cuttlefish's competitive success in variable environments. T...
