Meet our grantees
Wild Animal Initiative funds academic research on high-priority questions in wild animal welfare.
The goal of our grants program is to fund research that deepens scientific knowledge of the welfare of wild animals in order to better understand how to improve the welfare of as many wild animals as possible, regardless of what causes the threats to their well-being.
We showcase our grantees and their projects here and continuously update this page as new projects are added.
Development of octopus mind in the wild: a behavioral, ecological and evolutionary investigation into sentience and emotional states in Octopus insularis juveniles
Grantee: Michaella Andrade
Institution: Federal University of ABC
Project summary
There is evidence that evolutionary pressures can cause behaviors with opposite meanings to develop opposite forms, the way a frown is the opposite of a smile. One way to understand the expression of emotion in animals may therefore be to identify pairs of behaviors that are opposites. In octopuses, which are increasingly being recognized as sentient, colors can be signals of emotional valence during conflict and other situations. Yet no study has tested whether octopuses have opposite pairs of color signals. This project will produce descriptions of evolutionary and behavioral patterns that reflect the emotional states and sentience of juvenile octopuses, which may contribute to the welfare of octopuses and other invertebrates.

Project summary
Welfare refers to the quality of life of animals that possess sentient capacity and emotional states. Although the precursors of sentience were possibly present on the planet as early as 890 million years ago, the evolution of sentience is still poorly understood. However, cephalopods are increasingly being recognized as sentient, yet we do not know about this phenomenon in juvenile wild animals. In this sense, studies with wild animals can be beneficial for finding a wider range of ecological triggers and their relationship with behaviors.
There’s evidence that evolutionary pressures can cause behaviors with opposite meanings to eventually develop opposite forms, the way a frown is the opposite of a smile. One way to understand the expression of emotion in animals therefore may be to find pairs of behaviors that are opposites. In octopus, colors can be a signal of emotional valence during conflict and other contexts. Although researchers began to see this dimension in octopuses, no study has tested whether opposite pairs of color signals are present in octopuses. This project will produce descriptions of evolutionary and behavioral patterns that reflect the emotional states and sentience for juvenile octopuses, which may contribute to the welfare of octopuses and other invertebrates.
Why we funded this project
Although octopuses are widely assumed to be sentient at the adult stage, no studies that we are aware of have examined sentience at earlier life stages. As the vast majority of octopuses alive at any one time are juveniles, and octopuses have enormously high juvenile mortality, the question of when in their development sentience arises is particularly important. This project is also interesting because it will teach us about what the lives of juvenile octopuses are like and the extent to which welfare effects are mediated by personality traits.
