ONE species of deep-sea fish incubates its eggs in a seemingly impossible place: the baking hot rocks of hydrothermal vents. These seabed openings spew fluids from the planet’s bowels. “This is the first time this egg-incubating behaviour, using heat from active hydrothermal vents, has been recorded in the marine environment,” says Pelayo Salinas de León of the Charles Darwin Foundation in the Galapagos, Ecuador. He says the heat may speed up development. Salinas de León and his colleagues used a remotely operated vehicle to explore the Iguanas-Pinguinos hydrothermal vents,
