The identification and management of pain, suffering and distress in cephalopods, including anaesthesia, analgesia and humane killing
TLDR
A protocol for humane killing of cephalopods is proposed, along with development of humane methods of killing that will not compromise study of the brain, and key gaps in current knowledge are highlighted.
The effects of prospective anaesthetic substances on cephalopods: Summary of original data and a brief review of studies over the last two decades
TLDR
It is concluded that future investigations to improve the provision of stable, safe and reliable anaesthesia for cephalopods would probably benefit from combinations of higher doses for shorter exposure times, and the co-administration of two or more substances.
Morphological assessment of the Octopus vulgaris species complex evaluated in light of molecular‐based phylogenetic inferences
TLDR
The hypothesis that multiple O vulgaris‐like species are currently being incorrectly treated under a single species name, O. vulgaris, is supported.
Octopus sinensis d'Orbigny, 1841 (Cephalopoda: Octopodidae): Valid Species Name for the Commercially Valuable East Asian Common Octopus
TLDR
Recognizing O. sinensis as a species distinct from O. vulgaris is an important step towards improving sustainable fisheries management policies for each species in this group of commercially valuable octopuses.
The visual pigment chromophores in the retina of insect compound eyes, with special reference to the Coleoptera
TLDR
A new survey of the visual pigment chromophores in the compound eye of Japanese insects was made during the Summer and Autumn of 1988, and exceptions to the previously apparent, general phylogenetic trends are now known in the Orders Coleoptera, Diptera, Neuroptera and Odonata.
The Southern Ocean: Source and sink?
Many members of the benthic fauna of the Antarctic continental shelf share close phylogenetic relationships to the deep-sea fauna adjacent to Antarctica and in other ocean basins. It has been
Cephalopod culture: current status of main biological models and research priorities.
TLDR
This chapter aims to provide an overview of the culture requirements of cephalopods, to highlight the physical and nutritional requirements at each phase of the life cycle regarded as essential for successful full-scale culture.
SCREENING-PIGMENT MIGRATION IN THE OCTOPUS RETINA INCLUDES CONTROL BY DOPAMINERGIC EFFERENTS
TLDR
It is concluded that dopaminergic efferents from the optic lobes effect dark-adaptational SP migration in the cephalopod retina, demonstrating the arrival in the retina of efferent signals that effect adaptational changes through the mediation of dopamine.
World Octopus Fisheries
Abstract Recent studies have shown that coastal and shelf cephalopod populations have increased globally over the last six decades. Although cephalopod landings are dominated by the squid fishery,
A molecular sequence proxy for Muusoctopus januarii and calibration of recent divergence among a group of mesobenthic octopuses
TLDR
It is proposed that sequence data from M. normani can be used as a proxy for M. januarii and the timing of these two vicariance events provides a means of calibrating the recent divergence rate in the Muusoctopus group, which appears to be at least two to three times faster than reported previously.
