Feeling the heat

Scientists suspect that Pacific white skates are laying their eggs near hydrothermal vents to speed up their otherwise lengthy incubation process.<br data-lazy-src=
The remotely operated underwater vehicle (ROV) Hercules allows scientists to film the sea floor thousands of metres below the surface. Piloted by technicians aboard the research vessel, cameras can more easily venture into habitats that would endanger researchers.<br data-lazy-src=
A host of technologies, like ROVs, allow scientists to explore deep-sea habitats. This kind of capacity is vital to monitor changes to life in the deepest reaches. While these parts of the oceans remain relatively unexplored, human exploitation in the form of deep-sea mining and fishing is quickly catching up to even the hardest-to-reach regions.<br data-lazy-src=
