Assessing Negative Welfare Measures for Wild Invertebrates: The Case for Octopuses
Welfare metrics have been established for octopuses in the laboratory, but not for octopuses living in the wild. Wild octopuses are constantly exposed to potentially harmful situations, and the ability to assess the welfare status of wild octopuses could provide pertinent information about individuals’ health and species’ resilience to stressors. Here, we used underwater photos […]
Octopus vulgaris (Mollusca, Cephalopoda) as a model in behavioral pharmacology: A test of handling effects
Despite the great interest of Cephalopods in learning studies, behavioral pharmacological experiments using these animals are scanty. The purpose of this study was to find an appropriate method of injection of substances for studying their effects on the behavior of octopuses. We injected into the branchial heart a known volume of seawater to test the […]
Personality Traits in Dumpling Squid (Euprymna tasmanica) : Context-Specific Traits and Their Correlation With Biological Characteristics
Personality traits are a major class of behavioral variation often observed within populations of animals. However, little is known of the integration between personality and an individual’s underlying biology. To address this, the authors measured personality traits in squid (Euprymna tasmanica) in 2 contexts while also describing trait correlates with biological parameters. Four traits (shy […]
