Smithsonian scientists become shark detectives to track species in the Chesapeake Bay
A shark rests in a holding tank on a Florida expedition. Before and after having their tags inserted, the sharks are kept in small pools for comfort and recovery. (Photo by Jay Fleming) When many people think of the Chesapeake Bay, one of the first creatures that comes to mind is the iconic blue crab. But parts of the bay are also home to several species of shark. Scientists have…

Some dolphins cross the Pacific more easily than others. Why that matters for protecting them.
These eastern spinner dolphins from the eastern Pacific are a unique subspecies and look very different from spinner dolphins in other parts of the world. New research led by Smithsonian researcher Dr. Matthew Leslie (conducted at Scripps Institution of Oceanography and NOAA’s Southwest Fisheries Science Center) compared global patterns of DNA in spinner dolphins and pantropical spotted dolphins.

Meet the world’s weirdest whale
Narwhals breaching for air in an open space in the Arctic sea ice. (Photo by Glenn Williams) Swimming in the frigid waters of the Arctic and surfacing in narrow gaps in the sea ice to breath, the narwhal is one of the world’s most elusive and bizarre marine mammals. Considered by some as the jousting knight of the sea, this whale sports a single tusk sticking six to nine feet…

MarineGEO survey conducted in Hong Kong
This MarineGEO settlement structure was submerged in Tung Ping Chau for two years. Many of these eight-level structures deployed in and around Hong Kong were found to have more than 300 visible organisms living in and on them. (Image courtesy The University of Hong Kong) Some of Hong Kong’s most disturbed and pristine marine environments were the recent focus of an intense 10-day MarineGEO survey of living organisms by a…

Earth’s oceans are losing their breath. Here’s the global scope
Low oxygen caused the death of these corals and others in Bocas del Toro, Panama. The dead crabs pictured also succumbed to the loss of dissolved oxygen. (Credit: Arcadio Castillo/Smithsonian) In the last 50 years, the amount of water in the open ocean with zero oxygen has increased more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect…
