Pesquisador Joseph Garner, da Universidade de Pudue na Noruega afirma que peixes podem sentir dor.

 

Baseado em estudos com peixes dourados, Garner informa que os mesmo experimentam a dor de forma consciente, e não reagem por reflexo.
 

Foi observado que o peixinho que recebia uma injeção de salina e era exposto a um grau doloroso em um tanque de teste, ao voltar para seu próprio tanque ficava nadando em um único ponto.
 

Para Joseph trata-se de “comportamento de medo e evasão”, ou melhor, uma reação cognitiva e não resultante de reflexos. Peixes que receberam morfina – bloqueando a dor – não mostraram esse comportamento. Mas muitos especialistas não estão convencidos sobre o resultado das pesquisas de Garner.
