Sense and Insensibility – An Appraisal of the Effects of Clinical Anesthetics on Gastropod and Cephalopod Molluscs as a Step to Improved Welfare of Cephalopods

open access: yesFrontiers in Physiology, 2018
Recent progress in animal welfare legislation stresses the need to treat cephalopod molluscs, such as Octopus vulgaris, humanely, to have regard for their wellbeing and to reduce their pain and suffering resulting from experimental procedures.

Taxonomy and palaeoecology of continental Gastropoda (Mollusca) from the Late Pleistocene mammoth-bearing site of Bullendorf in NE Austria [PDF]

open access: yes, 2018

HELIX: Data-driven characterization of Brazilian land snails [PDF]

open access: yesarXiv, 2021
Decision-support systems benefit from hidden patterns extracted from digital information. In the specific domain of gastropod characterization, morphometrical measurements support biologists in the identification of land snail specimens. Although snails can be easily identified by their excretory and reproductive systems, the after-death mollusk body ...

Electrophysiological Organization of the Eye of Aplysia [PDF]

open access: yes, 1969
The eye of Aplysia californica was studied by electrophysiological and histological methods. It has a central spheroidal lens which is surrounded by a retina composed of several thousand receptor cells which are replete with clear vesicles, pigmented ...

Reversal of age-related learning deficiency by the vertebrate PACAP and IGF-1 in a novel invertebrate model of aging: the pond snail (Lymnaea Stagnalis) [PDF]

open access: yes, 2014
With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic ...

Octopamine increases the excitability of neurons in the snail feeding system by modulation of inward sodium current but not outward potassium currents [PDF]

open access: yes, 2005
Background: Although octopamine has long been known to have major roles as both transmitter and modulator in arthropods, it has only recently been shown to be functionally important in molluscs, playing a role as a neurotransmitter in the feeding network

Nociceptive Biology of Molluscs and Arthropods: Evolutionary Clues About Functions and Mechanisms Potentially Related to Pain

open access: yesFrontiers in Physiology, 2018
Important insights into the selection pressures and core molecular modules contributing to the evolution of pain-related processes have come from studies of nociceptive systems in several molluscan and arthropod species.

Evolution of molluscan hemocyanin structures [PDF]

open access: yes, 2013
Hemocyanin transports oxygen in the hemolymph of many molluscs and arthropods and is therefore a central physiological factor in these animals. Molluscan hemocyanin molecules are oligomers composed of many protein subunits that in turn encompass subsets ...

Effect of cadmium on cytosine hydroxymethylation in gastropod hepatopancreas [PDF]

open access: yes, 2017
5-Hydroxymethylcytosine (5hmC) is an important, yet poorly understood epigenetic DNA modification, especially in invertebrates. Aberrant genome-wide 5hmC levels have been associated with cadmium (Cd) exposure in humans, but such information is lacking ...

Students' knowledge on the African giant mollusk Achatina fulica in a public school in the Recife metropolitan region [PDF]

open access: yesBiotemas, 2007
The African giant mollusk Achatina fulica Bowdich, 1822 was introduced into Brazil in 1988 as a substitute for the European escargot Helix sp. This action did not induce the expected results and the gastropod has become an invasive species according to ...
