hydrothermal vent cracks in the ocean floor through which boiling hot, chemical-filled water flows. Chimneys form around these vents, and organisms surround these vents using chemosynthesis to feed
invertebrate creature without a backbone. Squid, octopi, sharks

mid-ocean ridge a huge undersea mountain range
mutualism a relationship between two organisms that benefit both
oceanography the science of the oceans
ostracod small, seed-shaped animal with two shells
photic zone area of the ocean in which sunlight penetrates enough to allow plants to survive. [to provide for photosynthesis]
photophore the glowing organ of a creature that contains light-producing chemicals
plankton one of many tiny plants or organisms that live in the ocean
seep an area of the ocean floor where hydrogen sulfide is released by the seeping of oil or natural gas up through the ocean floor
submersible vehicle designed for underwater exploration
submarine vehicle designed for military use under underwater
twilight zone area of the ocean below the sunlit zone (photic zone) and above the area of total darkness
