    Octopod on Submersible Arm

    A deep-sea octopod wraps itself around a submersible’s robotic arm 2,300 meters (7,546 feet) down in the Gulf of Mexico. "Most octopuses will let you get close, maybe even touch them, but normally they'll try to run once the manipulator gets close," said Bruce Strickrott, pilot of the submersible Alvin.

  • UV light illuminates growth rings in a cross-section of 44-year-old Primnoa resedaformis coral found about 400 m (1,312 ft) deep off Newfoundland.

    Coral Growth Rings

    Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old Primnoa resedaformis deep-sea coral collected off the coast of Newfoundland in about 400 m (1,312 ft) of water. Similar to tree trunks, cross-sections reveal coral-growth rings that can be used to determine their age.
