This specimen of the deep-sea coral Desmophyllum dianthus shows the visible bands that help marine scientists learn how ocean conditions changed over time. By looking at the thickness of each band,...
Bacteria are everywhere in the ocean. They live in the water, on virtually every living and non-living surface, and even inside other organisms . There are 1 million bacterial cells in every...
A marine scientist performs a genetic analysis on a sample of deep-sea coral to find out if it is a known species or one new to science. Find out how ocean scientists study deep-sea corals in our...
Sea stars are important members of marine ecosystems, especially in the tropics. We may think of tropical coral reefs as being home mainly to fish and corals, but in fact these habitats are home to a...
