From the same land that transparent frogs were created in, comes the see-through goldfish. Japanese scientists hope that due to the organs and heart being visible, it'll eliminate the need to dissect them in schools and laboratories.
To be honest, I don't seem to recall slicing and dicing goldfish in biology class—but then, I was probably hiding in sickbay claiming vegetarianism. Perhaps goldfish dissections are more common in Japanese schools than anywhere else?
Anyway, the goldfish skin and scales lack pigment, which means all organs—including the heart and brain—are visible. Wonder when the same scientists will create transparent humans? [Scienceray]
