Joseph Garner, an assistant professor of animal sciences, helped develop a test that found goldfish do feel pain, and their reactions to it are much like that of humans.
"There has been an effort by some to argue that a fish's response to a noxious stimuli is merely a reflexive action, but that it didn't really feel pain," Garner said. "We wanted to see if fish responded to potentially painful stimuli in a reflexive way or a more clever way."
Garner and Janicke Nordgreen, a doctoral student in the Norwegian School of Veterinary Science, attached small foil heaters to the goldfish and slowly increased the temperature. The heaters were designed with sensors and safeguards that shut off the heaters to prevent any physical damage to a fish's tissue.
Comment: The only problem with this debunking theory is that the chevrons in Madagascar are made of material from the ocean floor with sediment hundreds of meters deep and containing microfossils that are fused with metals typically formed by cosmic impacts.
Unless sea level has changed drastically in 5,000 years this "counter theory" (which is not a theory at all since it's not explaining what has caused these chevrons) is far more worthless than the theory it's trying to replace.
