Article: orcas confined within oceanaria

Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may apply, or in captivity, where access is constrained for commercial and safety reasons. From 1979 to 1980, however, my co-authors were able to interact with juvenile orcas in an unstructured way at San Diego’s SeaWorld facility. They observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, and empathetic behaviors. Their observations were consistent with those of a former Seaworld trainer, and provide important insights into orca cognition, communication, and social intelligence. However, after being trained as performers within Seaworld’s commercial entertainment program, a number of orcas began to exhibit aggressive behaviors. The orcas who previously established apparent friendships with humans were most affected, although significant aggression also occurred in some of their descendants, and among the orcas they lived with. Such oceanaria confinement and commercial use can no longer be considered ethically defensible, given the current understanding of orcas’ advanced cognitive, social, and communicative capacities, and of their behavioral needs.

Symposium: impacts of ‘Brexit’ on animal welfare

Over 8 billion animals are killed in slaughterhouses and in the fishing industry in the UK each year. What are the likely impacts of ‘Brexit’ on animal welfare - and particularly, on the pain and distress animals experience during slaughter? Join a high profile list of speakers and colleagues at a symposium on Raising Standards at the Time of Slaughter: Analysing the Potential Impact of ‘Brexit’ upon Animal Welfare, in London, on Tuesday 20th September 2016, organised by the Public Policy Exchange. I’ve been asked to chair this event. A 20% early registration discount is available for all bookings received by 19th August 2016.
