Crecimiento relativo del estatolito de Sepia officinalis (Cephalopoda, Sepioidea) de la ría de Vigo [PDF]
, 1985 En este trabajo se pone de manifiesto que el crecimiento de los estatolitos de Sepia officinalis es alométrico. Tanto el peso como la longitud del estatolito experimentan un retardo del crecimiento con respecto al tamaño de los individuos de ambos sexos,

A decline in the energy content of forage fish in the Bay of Biscay
Journal of Fish Biology, Volume 107, Issue 4, Page 1447-1453, October 2025.Abstract Planktonic production fuels the base of marine food webs and can mediate energy accumulation in consumers but is affected by several anthropogenic pressures. Our understanding of how shifts in prey quality at various trophic level shape marine food webs remains poor.

Redox activity of melanin from the ink sac of Sepia officinalis by means of colorimetric oxidative assay [PDF]
, 2015 The redox properties of natural extract from cuttlefish ink sac (Sepia officinalis) and synthetic melanin used as a biomimetic in melanin structural investigation were determined by comparison of this phenol-based heterogeneous pigment with gallic acid ...

Natural Habitat and Wild Behaviors of the Dwarf Cuttlefish, Ascarosepion bandense
Ecology and Evolution, Volume 15, Issue 9, September 2025.Gibbons et al. performed a field study to characterize the dwarf cuttlefish—a popular aquarium and research cephalopod—in its natural habitat. They observed dynamic camouflage, social behaviors, and use of an expanded color palette in wild animals compared to laboratory animals.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.ABSTRACT Scientific literature supports the benefits of trawling bans for fish assemblages, particularly regarding species richness and fish size, besides the health of food webs and seafloor habitats. Length‐based indicators are commonly applied to track the recovery, offering straightforward and sensitive metrics for detecting shifts in population ...

Scientia Marina, 2006 The small-scale cuttlefish (Sepia officinalis) fishery in Galician waters (NW Spain) was studied using a model based on data obtained from fishers. This model was applied using information obtained from the small-scale Galician fleet in 1998.

The use of Depletion methods to assess Mediterranean cephalopod stocks under the current EU Data Collection Framework [PDF]
, 2016 Fuelled by the increasing importance of cephalopod fisheries in Europe, scientists and stakeholders have demanded their assessment and management. However, little has been done to improve the data collection under the EU Data Collection Framework (DCF ...

Camouflage Using Surface Disruption: The Importance of Corners Versus Edges
Ecology and Evolution, Volume 15, Issue 8, August 2025.Disruptive colouration allows animals to avoid predation by concealing the body's outline or surfaces. If corners are important for shape processing, as in human vision, then corner disruption should provide better camouflage than edge disruption. Although the location of surface disruption did not influence survival, we found that 3D prey had higher ...

Cuttlefish responses to visual orientation of substrates, water flow and a model of motion camouflage [PDF]
, 2006 Low-level mechanisms in vertebrate vision are sensitive to line orientation. Here we investigate orientation sensitivity in the cuttlefish Sepia pharaonis, by allowing animals to settle on stripe patterns.

Motion After‐Effects Induced by Dynamic Illumination in Crab Vision
Ecology and Evolution, Volume 15, Issue 5, May 2025.While in humans, background motion can disrupt the detection of visual cues even after the moving background component has ceased, it remains unknown whether natural forms of background motion might also affect other animal visual systems. Here, we test whether prior exposure to naturally occurring ‘caustics’, a form of dynamically moving light ...
