"The premise of this excellent book by Durrant (Victoria Univ. of Wellington, New Zealand) is that many invertebrate species are likely to be sentient―they have the capacity for subjectively felt experiences―and hence should be considered to have at least some moral standing. … Non-speciesist criminology has needed a book like this for quite some time. It is a major and highly original contribution. … Highly recommended. Advanced undergraduates through faculty " (P. Beirne, emeritus, Choice, Vol. 62 (9), 2025)
