Evidence of play behavior in captive California two-spot octopuses, Octopus bimaculoides

Play is considered to be an essential part of development that supports learning, memory, and the development of flexible behavioral strategies. It may also serve as an informative factor in assessing an animal’s welfare state and in improving care and...

Stress induced by fishing in common octopus (Octopus vulgaris) and relative impact on its use as an experimental model (2025)

The common octopus (Octopus vulgaris), among coleoid cephalopods, has evolved the most complex nervous system and sophisticated behaviors. Historically, O. vulgaris was a key animal model for neurophysiology research, and today, it is studied for its genomic innovations. However, unlike...

Defending and refining the Birch et al. (2021) precautionary framework for animal sentience (2025)

It is widely accepted that we ought to avoid taking excessive risks of causing gratuitous suffering. The practical implications of this truism, however, depend on how we understand what counts as an excessive risk. Precautionary frameworks help us decide when...

Personality dimensions in the common octopus (Octopus vulgaris)

Understanding the origin, universality, and maintenance of among-individual variation in behaviour is a current focus of behavioural ecology and comparative psychology. Research on animal personality emphasising the central role of the individual contributes to conservation efforts and animal welfare by...

Stress produces negative judgement bias in cuttlefish

Judgement bias tasks (JBTs) are used to assess the emotional state and welfare of animals in zoos, farms and laboratories, based on the interpretation of an ambiguous or intermediate cue. Animals in positive affective states are more likely to interpret...

General and species-specific recommendations for minimal requirements for the use of cephalopods in scientific research

Here we list species-specific recommendations for housing, care and management of cephalopod molluscs employed for research purposes with the aim of contributing to the standardization of minimum requirements for establishments, care and accommodation of these animals in compliance with the...

Improving keeping for octopuses by testing different escape-proof designs on tanks for “big blue octopus” (Octopus cyanea)

Octopus cyanea has a wide range of natural distribution and is interesting for scientific research. However, unlike Octopus vulgaris, the species is poorly studied, and few data exist on best practices for keeping them. One of the most common reasons...

Perspective: Opportunities for advancing aquatic invertebrate welfare

Welfare considerations and regulations for invertebrates have lagged behind those for vertebrates, despite invertebrates comprising more than 95% of earth's species. Humans interact with and use aquatic invertebrates for exhibition in zoos and aquaria, as pets, research subjects, and important...
