Deep-sea fish use hydrothermal vents to incubate eggs (video)

An international team of researchers, including Penn State biologist Charles Fisher, discovered eggs of deep-sea skates near hydrothermal vents. The researchers believe the fish are using the volcanic heat emitted from the hydrothermal vents to accelerate egg development. (Video credit: Ocean Exploration Trust, Penn State).
