The challenge of designing a device to learn what marine mammals do on dives is the stuff of dreams for an electronics engineer.
For the first time in history, we can accompany a whale on its dive, hear what it hears, and observe its normal, natural, previously hidden behavior in the depths. Working closely together, scientists and engineers have created an innovative new device—the digital acoustic recording tag, or D-tag. It attaches to a living whale and records nearly everything that happens on its dives, without disturbing the animal.
One group of bacteria—the cyanobacteria—has completely transformed Earth’s environment through their long history. Three billion years ago, ancestors of cyanobacteria infused Earth’s ancient atmosphere with the byproduct of their photosynthesis—oxygen—changing the chemistry of the planet and setting the stage for entirely new oxygen-breathing life forms to evolve. Without the cyanobacteria, the life we see around us, including humans, simply wouldn’t be here.
For decades, the Nassau grouper (Epinephelus striatus) was one of the most sought-after fish species in the Caribbean and Gulf of Mexico, from the Bahamas to Central America. These large, delicious fish live among coral reefs and have a breeding behavior that makes them especially vulnerable. They come together in aggregations of thousands to spawn at specific times and places, making them easy to catch—and to overfish.
The words “coral reefs” conjure up images of a tropical paradise: shallow, warm, aquamarine waters, bright sunlight, white coral sand, and colorful, darting fish. But corals also live deep in the sea, in regions where the sun doesn’t penetrate and water temperatures remain just above freezing.

April 24 marks the first-ever Right Whale Day in Massachusetts. WHOI biologist and veterinarian Michael Moore recently met with the resident who brought this special recognition about– and explains why it’s important to raise awareness about the critically endangered North Atlantic right whale.
A report out this week in Current Biology reveal that critically endangered North Atlantic right whales are up to three feet shorter than 40 years ago. This startling conclusion reinforces what scientists have suspected: even when entanglements do not lead directly to the death of North Atlantic right whales, they can have lasting effects on the imperiled population that may now number less than 400 animals. Further, females that are entangled while nursing produce smaller calves.
