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!

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.

A Blue View: Clownfish

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 9, 2014: Clownfish

clownfish and the important role
they play in the health of coral reefs!

Parents of young children know a thing or two about clownfish. These adorable orange and white fish rocketed to stardom in the animated classic Finding Nemo, which featured an adventurous clownfish hero.

Finding Nemo

Clownfish popularity, however, extends far beyond the preschool set. The movie led to an upswing in their demand within the exotic pet trade – they are now one of the most popular saltwater aquarium fish.

That was the downside of the Nemo-effect. The upside? More people became interested in coral reef conservation. It is an ecosystem of tremendous importance, fragility and interdependence, and clownfish are an indicator species for reef health.

Further, they are truly fascinating creatures. When Nemo’s dad, Marlin, names all of the eggs Marlin Junior, the moviemakers got the science right: all clown fish are born male. Many fish species are able to change sex, almost always from female to male. But the clownfish is different, changing gender only to become the dominant female of the group, and that change is irreversible. In a clownfish group living in an anemone the largest fish is female, the second largest a male. They are the mating pair.

But the adventure story of Nemo’s dad traveling far and wide to find his son? Unscientific. In the wild, clownfish never venture far from their anemone. It’s home…and pantry. It’s this interdependence that has earned the fish their full name: the anemone clownfish.

The relationship between anemones and anemone clownfish is a classic oceanic partnership of mutualism.

In science, mutualism is defined as a relationship between two species in which both benefit from the association. In fact, clownfish and anemones probably couldn’t live without each other, which qualifies them as “obligate symbionts.”

They couldn’t be more different, yet they need each other to survive. The clownfish is a vertebrate, while a sea anemone is an invertebrate, closely related to corals and jellyfish. And like them, its sting is deadly to most other creatures.

So how does the clownfish manage to live among the anemone’s lethal tentacles? Well, very cautiously. As the clownfish gets to know its anemone, it does an elaborate ballet of tentative darting movements, touching the anemone’s stinging tentacles gently, working up immunity and a protective layer of mucus.

Once they’ve acclimated to each other, they eat each other’s food scraps. The anemone’s tentacles provide the clownfish with protection from predators. The clownfish protects the anemone from predators like the butterfly fish and nibbles the anemone free of parasites. Cozy, right?

But scientists have recently discovered that there is additional complexity to the relationship.

The anemone benefits from the clownfish’s ammonia-rich waste. It’s like anemone fertilizer: it helps the animal grow.

After all, a bigger anemone is better for both; its larger tentacles can snare larger, more nutritious prey and the clownfish gets better leftovers and more spacious living quarters.

There’s also a fascinating nocturnal half to the anemone-clownfish routine. Scientists used to think that at night the clownfish snuggled quietly inside the anemone. But Dr. Nanette Chadwick and her team at Auburn University recently discovered that the clownfish moves around more than was suspected, reminiscent of a dog trying to get comfortable on its dog bed.

The clownfish’s movements oxygenate the water deep within the anemone’s tangle of tentacles. In effect, the clownfish helps the anemone breathe.

Clownfish and anemones literally cannot live without one another. In the sea, as in Hollywood, they call that chemistry!

Neon Gobies in Atlantic Coral Reef 

Two neon gobies have been added to our Atlantic Coral Reef exhibit!

national aquarium neon goby

Generally, neon gobies only grow to be about 1 inch in length.

Did you know? Gobies are cleaner fish! These animals can oftentimes be observed in grouped “cleaning stations” throughout the reef, where larger fish like damselfish or grunts can stop by for a quick parasite removal.

Gilded Triggerfish in Blacktip Reef

If you’ve tuned into Shark Cam lately, chances are you’ve spotted Blacktip Reef‘s gilded triggerfish!

national aquarium gilded triggerfish

The gilded triggerfish, also known as the blue-throated triggerfish, can be found throughout the reefs of the Indo-Pacific. This is one of approximately 40 species of triggerfish identified worldwide.

Triggerfish are normally shy and solitary, but they can be very aggressive. Some may charge or attack intruders. When hiding from predators, triggerfish lock themselves into small openings with their trigger fin and bite down on the coral or rock to ensure their safety.
