Tuesdays 5:44 PM

A Blue View, hosted by National Aquarium CEO John Racanelli.  From the smallest plants and animals invisible to the human eye to entire ecosystems, every living thing depends on and is intricately linked by water.

The largest turtle on Earth is the leatherback sea turtle, with a shell that’s up to 8 feet wide and a weight of more than 2,000 pounds. Sound big? Well, it is—until someone mentions Archelon, an ancient genus of monster turtles that once lived in a shallow sea covering what’s now South Dakota. Extinct for 80 million years, Archelon turtles made the leatherback look like, well, a shrimp.

Cascading tendrils of blue-green tentacles and a translucent, neon bell give the Portuguese man-of-war its otherworldly appearance.

The Greenland ice sheet is melting. Global temperatures are increasing. Sea level is rising. We've known this for awhile. So what's news? It's the pace of these changes.

Did you know? One out of every three bites of food you eat comes from pollinators. Without them, we wouldn’t have foods like blueberries, apples, chocolate and almonds.

In the vast midwaters of the open ocean, there’s an animal so adorable that the Smithsonian Institution’s website said, "If this video doesn't inspire a whole cadre of budding teuthologists, we don't know what will." Any amateur teuthologists out there want to hazard a guess as to what group of animals they’re referring? Here’s a hint: teuthology is the study of squids and octopuses.

Manatees made headlines this winter when a group of them, including a mother and calf, became marooned in a Florida storm drain and had to be rescued by marine biologists with backhoes and earth-moving equipment. Why such heavy machinery?

Each year, over 2,300 pieces of legislation are introduced into the Maryland General Assembly. This year, one bill has the potential to make an impact on reducing the amount of pollution that enters our waterways.

When you think of an animal that purrs, grunts, croaks or hums, I’ll bet it’s not a fish. But, I’ll let you in on a secret: More than 150 species of fish on the East Coast of the U.S. are what scientists call “somniferous.” They make noise. Lots of it.

Many of us have a romantic image of fishing: a weather-beaten waterman aboard a small fishing boat, hauling in a handmade rope net as a sou’wester approaches.

Our planet is misnamed. With 71 percent of it underwater, what we call Earth is really a water planet. For us earthlings, who can only thrive on land, that’s a problem, one compounded by our inability to live where it’s too cold, hot, dry or wet for us.

For most fish, the line Dory utters in the popular Disney movie “Finding Nemo” is no exaggeration. Sounds exhausting, right? But you’re unlikely to catch a fish closing its eyes for a quick catnap.

Imagine if the air you breathed changed your behavior. You might become reckless or disoriented, even experience loss of sight or sound. Yet, what if you had to breathe that bad air anyway, just to survive? This is a scenario that many fish and other aquatic animals could actually face in the near future, with the very seawater that they rely on to exist.

Zooplankton, the microscopic invertebrates consisting of small animals and the immature stages of larger animals, move up and down the water column in a type of migration called diel vertical migration.

Need an icebreaker for your next dinner party? Here’s one you can share while nibbling hors d'oeuvres: “Did you know your skull and head is organized like an extinct jawless fish?” Take your philtrum, for example. That’s the groovy indentation on your top lip just beneath your nose.

"This is the ship of pearl, which poets feign, sails the unshadowed main / and its dim dreaming life was wont to dwell /as the frail tenant of its growing shell." Oliver Wendell Holmes described this remarkable creature in his 1858 poem “The Chambered Nautilus.”

It's easy to think of science as clear, clean and linear - the progressive accumulation of information driving a steady increase in our understanding of the world.  But, in truth, it's messy.  There are fits and starts. Bafflement. Wrong turns. Dead ends.  Head-scratching questions that defy answers. There are also a lot of happy accidents, often made by people not even in science - as the workers on an oil and gas rig off the coast of Angola discovered in August of 2015.

If you had to guess the most common vertebrate on the planet, you might say deer or squirrels. Maybe mice or factory-farmed chicken? Even humans?

Earth’s ice is expansive. In fact, 10 percent of the planet’s land mass is covered in ice—like glaciers, ice caps and ice sheets—spanning more than 5 million square miles.

The sea lamprey looks like the stuff of nightmares. An eel-like fish with a suction-cup mouth, 100-plus teeth and file-like tongue, it’s easy to imagine it searching the ocean, bays and lakes for its next meal.

Large, silvery-brown, snout-nosed, scute-covered, prehistoric-looking Atlantic sturgeon have been swimming the seas and coming up East Coast rivers to breed since dinosaurs roamed the Earth.

You’d have to drive from California to New York and back—TWICE—to fully appreciate the distance traveled by the gray whale every year. This species takes the credit for longest migration route of any mammal, traveling 12,000 miles from the icy waters of the Arctic to the warm lagoons of Baja, Mexico, and back again.

We have five senses; ask any schoolchild and they can rattle them off on the fingers of one hand: hearing, taste, smell, touch and sight.

When it comes to biodiversity, the Amazon is practically unrivaled. Spanning 6.7 million square kilometers, this South American region is twice the size of India and houses at least 10 percent of the world’s known species. Twelve hundred new species of plants and vertebrates were discovered between 1999 and 2009 alone.

Tridacna gigas, the giant clam of the Indo-Pacific, is the largest bivalve mollusk on Earth and the world's only sun-powered clam. It hosts a thick layer of zooxanthellae in its tissues and gets up to 90 percent of its nutrition from their photosynthesis.

Where does your seafood come from? You may be thinking about your favorite restaurant or your local grocery store. But the fact is, some seafood takes a circuitous route to get from the sea to your plate, and along the way can get a little, well, lost.

Its eye is the size of your head. It lives more than 3,000 feet deep in oceans around the world and is 30 feet long, yet it lacks a backbone. With eight arms and two tentacles, it is the origin of the myth of the Kraken.

We talk a lot about being “sustainable,” but what does it really mean? Tj Tate, director of sustainable seafood at the National Aquarium, is here today to talk about this sometimes misunderstood term, and what it means in the seafood industry.

When it comes to biodiversity of plants and animals, the number of species typically increases as you move from the colder temperate zone to the warm tropics. The epicenter of salamander diversity, however, exists much further from the Equator—in fact, it’s here.

You may not be able to dance, but you do have rhythm. All humans have rhythm. It is the circadian clock, a 24-hour cycle that regulates our sleep-wake timing and other physiological processes.

Perhaps you are familiar with the saying “an albatross around your neck.” This phrase, coined by the poet Samuel Taylor Coleridge, in his 1798 poem, The Rime of the Ancient Mariner, refers to the association of the albatross with bad luck, mishap, struggle and worry.
