Most ocean life remains to be discovered. Because fish and many other animals that live in the ocean often have larvae or other, microscopic life stages that drift freely in ocean water, counting species by genetic barcoding of plankton samples adds to counts of species recorded as adults and is a highly efficient way to understand what lives in the ocean and how biodiversity changes as we modify the ocean environment.
Most coral species fared better in the shaded environment offered by the mangrove canopy
Sharks’ bodies are covered with tiny, tooth-like scales called denticles. Shed denticles settle to the ocean floor, where they remain in sediments for years and can be used to understand which sharks lived on a reef in the past.
Picture this: What to do at a party when you try to carry on a conversation, but the music is too loud? A Panamanian doctoral student is trying to figure out how dolphins communicate underwater during heavy boat traffic in the Bocas del Toro Archipelago.
At the Smithsonian’s Bocas del Toro Research Station, in Panama, marine biologist Rachel Collin runs an educational program that recruits international experts to teach and create videos about how to collect, preserve and observe marine invertebrates, passing down their very specific knowledge to aspiring taxonomists.
The next time you eat seafood, think about the long-term effects. Will consistently eating the biggest fish or the biggest conch, mean that only the smaller individuals will have a chance to reproduce?
