It’s estimated that tens of millions of sharks die from incidentally being caught in fishing gear each year—more commonly known as bycatch—from longlines, trawls, and gillnets.

- Researchers say that some sharks in the Gulf of Mexico are decreasing in size, and in some cases are down by as much as 70 percent.

From whales to sea turtles and caribou, both terrestrial and marine animals are satellite-tagged around the world. Satellite tags—radio transmitters that submit signals to orbiting satellites—are an effective way to study animal behavior, including foraging and migration patterns.
