Extinction is a real possibility for three species of tunas. That’s one of the messages from a new study released today online in the journal Science . Researchers assessed the range and populations...
Animals, on land and in the ocean, live in a 3-D world, and they depend on their sense organs and brains to build the mental constructs that allow them to orient and navigate, which is crucial for...
Over the past several decades, Florida’s coastal wetlands have been changing. Along the eastern shore, researchers have seen small mangrove trees appearing in areas further north than they usually...
Have you ever seen a creature so unusual? This fish (22 cm long) is called a sea toad and studying them requires luck and the opportunity to descend into the deep waters where they live. Last week Dr...
I am once again leaving my familiar world behind and descending into the abyss below. The first dive of an entirely new expedition is the most magical. I am a member of a scientific research dive...
How do we know where ocean animals swim day and night? Scientists are getting snapshots into the daily lives of whales , sharks , and even fish by tagging the animals to track their movements. You’ve...
Welcome to Citizens of the Sea , a new blog series where ocean life comes to life. Our book by the same name came out in September, but no sooner had it gone off to the printer than new ocean stories...

Fever. Aching muscles. Coughing. Sniffling. It’s flu season . Have you had your shot? If so, thank a horseshoe crab. In fact, if you’ve been put on an IV, had a medical device implanted, or received...
The pre-industrial American landscape was once rightly described as a place where “the deer and the antelope roam.” On land, we take it for granted that the plant-eating deer and antelope far...
