Clark, F. E. 2013. Marine mammal cognition and captive care: A proposal for cognitive enrichment in zoos and aquariums. Journal of Zoo and Aquarium Research 1(1), 1–6.

Marine mammals, particularly cetaceans (whales, dolphins and porpoises) and pinnipeds (seals, sea lions and walruses) are popular in zoos and aquariums worldwide. Bottlenose dolphins and California sea lions have also been popular study species in...

Cognitively challenging environments are vital to the welfare of captive animals. However, practical enrichment devices that can facilitate animals’ natural behaviours and accommodate individual variation are still limited. We created two types of feeders to...

To understand the evolutionary development of cognition, comparing the cognitive capacities of different animal species is essential. However, getting access to various species with sufficient sample sizes can be very challenging. Zoos, housing large ranges...
