Spotted Lagoon Jellies in Jellies Invasion!

We have spotted lagoon jellies now on exhibit in Jellies Invasion: Oceans Out of Balance!

Did you know? Instead of a single mouth, this species of jelly has many small mouth openings on its oral arms, which capture plankton.

These jellies love the sunlight! It fuels the growth of symbiotic algae in their tissues, giving them a greenish-brown to blue color in the wild.

Spotted lagoon jellies can be found throughout the South Pacific!

A Blue View: Floating Forests

A Blue View is a weekly perspective on the life aquatic, 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.

Tune in to 88.1 WYPR every Tuesday at 5:45 p.m. as John brings to the surface important issues and fascinating discoveries making waves in the world today.

April 16, 2014: Floating Forests

the important role mangrove forests
play in the health of our oceans!

Gardeners in Maryland know that most trees in our temperate climate don’t like having wet feet. And water that’s salty? Forget about it. Around here, having tree roots submerged in saltwater is guaranteed to kill off your landscaping.

But far south of the Chesapeake, fringing tropical and subtropical coastlines, there exist floating forests of mangroves, whose roots grow in a luxuriant tangle at the ocean’s edge. And there, they thrive.

Botanists call the 50 species of mangroves halophylic, or “salt loving.” Mangroves have adapted to putting down roots where other plants can’t: in areas inundated daily by the tide; in thin, nutrient-poor, low-oxygen soils; and in water that varies from fresh to brackish to salty. Just how much salt can mangroves tolerate? Well, typical seawater has a salinity of 35 parts per thousand; in other words, about 35 grams of salt for every liter of sea water. Some species of mangroves can survive in salinities of more than 90 parts per thousand!

To thrive in this salty abundance, these plants need strategies to clear the excess salt. Some species excrete it through glands in their leaves. Others use their roots.

The weird, knobby roots of mangroves actually make traveling to paradise for a tropical vacation possible—tough, woody evergreen mangroves stabilize the soil and prevent many islands from simply washing away.

Thank the mangroves, too, for the colorful diversity of fish and invertebrates you see on your next coral reef dive. Many oceanic and coral reef fish—including snapper, tarpon and lobster—spawn in the nursery provided by the mangrove’s submerged tangle of roots. A mangrove forest is a rich hub of biodiversity, supporting a unique ecosystem of bacteria, plants, mammals, amphibians, invertebrates and birds—some found nowhere else.

Earth’s largest mangrove forest—the Sunderbans of India and Bangladesh—is a UNESCO World Heritage Site, home to at least 250 species of birds, endangered estuarine crocodiles and even Bengal tigers!

In North America, mangrove swamps are found throughout the Gulf Coast, from Florida to Texas. The largest mangrove forest in the United States is in Florida’s aptly named Ten Thousand Islands National Wildlife Refuge. This special place is home to many endangered species, including West Indian Manatees, and clouds of scarlet ibis and white pelicans.

The scarlet ibis typically inhabits mangrove swamps ranging from northern South America southward along the coast of Brazil, occasionally making visits in Florida.

Although mangrove forests host so-called “charismatic megafauna” like manatees and tigers, truly their greatest treasure may be the thick mud of mangrove leaf litter—fertile with bacteria and fungi—that accumulates in the water below the trees. There, detritivores, like crabs and other animals, feed on decaying leaf litter and contribute to a complex food web that begins, literally, in the mud.

Other microfauna encrust the mangrove’s submerged roots, including a profusion of filter feeding mussels and barnacles. Like Chesapeake’s oysters, mangrove barnacles efficiently filter pollutants from the water.

These crustaceans and mollusks in turn support populations of shrimp and fish that are economically important to Gulf of Mexico fisheries. So, the next time you’re dining on sustainably-caught shrimp, take a moment to thank a mangrove for your meal.

Animal Rescue Update: 13 Turtles Ready for Release This Week!

national aquarium Animal Rescue Update

Our Animal Rescue team is excited to announce that 13 of our current sea turtle patients in rehabilitation are going to be released this week! Animal Rescue and Animal Health staff have been busy the last few weeks clearing patients for releasing, making sure all releasable turtles have their required tags, and making sure we have all the pertinent paperwork and permits for the transport and release.

This Wednesday, several staff from the National Aquarium will pack the turtles for their long road trip south. So, how exactly do you transport a sea turtle? Each turtle is fitted for an appropriate sized transport carrier, which is padded with foam and towels to provide lots of cushion and support.

Each turtle will receive some fluids just under their skin to help keep them hydrated, and they’ll also get a water-based lubricant massaged onto their shell to help retain moisture, and some sterile eye lubricant helps keep their eyes moist. Finally, each turtle will be packed into our temperature-controlled transport vehicle and will be safely secured for the transport.

Once our vehicle is ready, our staff will make the 800 mile drive to northeast Florida to release the turtles. We’ll have a total of 9 Kemp’s ridley and 4 green sea turtles to release on this trip, and the much warmer waters of Florida are perfect this time of year.

Stay tuned for more updates on their release, as well as updates on our remaining rehab patients!

Animal Update – April 11

Mary River Turtle in Animal Planet Australia: Wild Extremes

A Mary river turtle is now on exhibit in our Animal Planet Australia exhibit!

Mary River Turtle

Australia’s largest species of freshwater turtle can only be found in the southeastern region of Queensland’s Mary River – the derivative of its common name. Due to its isolated range and a high pet trade demand for the species in the ’60s and ’70s, the Mary river turtle is currently one of the top 25 most endangered turtle species in the world.

Did you know? The tail of a Mary river turtle is lined with gill-like structures, which they use to extract oxygen from the water and remain submerged for long periods of time!

Thoughtful Thursday: Inspiring the Next Generation of Ocean-Lovers

Our celebration of National Volunteer Appreciation Week continues with a special story about one of the Aquarium’s volunteers and her students!

Abbe Harman has been a volunteer supporter of the National Aquarium for 28 years and a teacher for for Frederick County Public Schools for 25 years. As an Enrichment Specialist at Middletown Elementary School, Abbe works closely with fifth grade students, teaching them about the Chesapeake Bay watershed and coral reef ecosystems!

Yesterday, Abbe hosted a large group of her fifth graders for a special field trip tot he Aquarium! The students were able to see their teacher in-action, as she led an interactive lesson and fed the animals in our Atlantic Coral Reef exhibit!

In the weeks leading up to their field trip, Abbe’s students also had the opportunity to enter an essay contest for the opportunity to go on a special behind-the-scenes tour of the Aquarium.

Abbe, from all of us here at the National Aquarium, thank you for being a longtime supporter of our mission and an impactful educator.

Do you volunteer? Share your story with us in the comments section and online using #NVW14!
