| Popis: | Whether fish are sentient beings remains an unresolved and controversial question. Among characteristics thought to reflect a low level of sentience in fish is an inability to showstress-induced hyperthermia (SIH), a transient rise in bodytemperature shown in response to a variety of stressors. This is a real feverresponse, so is often referred to as ‘emotional fever’. It has been suggestedthat the capacity for emotional fever evolved only in amniotes (mammals,birds and reptiles), in association with the evolution of consciousness in thesegroups. According to this view, lack of emotional fever in fish reflects a lackof consciousness. We report here on a study in which six zebrafish groupswith access to a temperature gradient were either left as undisturbed controlsor subjected to a short period of confinement. The results were striking: compared to controls, stressed zebrafish spent significantly more time at highertemperatures, achieving an estimated rise in body temperature of about2–48C. Thus, zebrafish clearly have the capacity to show emotional fever.While the link between emotion and consciousness is still debated, this findingremoves a key argument for lack of consciousness in fish. |
