Researcher examines egg case from a deep-sea skate

DNA analysis revealed that the egg cases found near the black smoker belong to the skate species Bathyraja spinosissima, commonly known as deep-sea skates. The researchers believe the fish use the volcanic heat emitted from the hydrothermal vents to accelerate the typically years-long incubation time of the eggs.
