Lunchtime with the Shorebirds

The shorebirds exhibit at the Aquarium is a quiet, sunny oasis for the rescued birds that live there. Watching them bop up and down the exhibit's shoreline, listening to them cheep and squawk, is also a treat for visitors.

The shorebirds get the corner office with a view of Boston Harbor.

But mealtime might make some folks squirm.


This day, our aquarists fed the birds a tasty buffet of beetle larvae, served up in trays and distributed discretely around the exhibit. The trays keep the larvae from wriggling into the sand and pebbles in the exhibit. The fish-eating birds — the common terns and black skimmer — also dine on frozen (then thawed) silversides and capelin, which are also on the menu for other Aquarium animals like the penguins and large fish in the Giant Ocean Tank. And no, they don't actually eat the fish in the exhibit!

Preparing lunchtime for the shorebirds

And now and then, the aquarists also release a jar of crickets into the exhibit. That's when you can really see the birds forage!

Special delivery for the shorebirds: crickets

In the wild shorebirds rely heavily on bugs and crustaceans they find on the beach, mainly in the wrack, or seaweed, that washes up and is found along the high tide line. In our exhibit, however, it would be a lot of work to constantly haul 50 pounds of wrack into the everyday and we might not know how much the birds are eating.

Most of the shorebirds in the exhibit were injured and could not survive on their own in the wild. There are the common terns, Ike and Truro, the semipalmated sandpiper, and piping plover. On your next visit to the Aquarium, be sure to take a moment to watch the shorebirds in their exhibit—you'll be transported to warm summer days at the shore no matter what the weather is like outside.

Baby Seahorses: Four-Month Check In

It takes about 9 months for baby lined seahorses to grow to full size. So you can imagine that the young'uns born this past September are already well on their way to adulthood. Let's take a walk down memory lane to see how these amazing creatures have grown over the past few months!

Here's a collection of pictures of the baby seahorses, starting with newborn pictures from last September.

September (squeee!): Newborn seahorses float around their small exhibit around the corner from their parents 
October: Still free floating but getting bigger
December: Their tails are stronger and grabbing onto the habitat added to their exhibit
Early January: Coloration getting much darker
Late January: Starting to look like tiny adults!
For comparison, here's an adult lined seahorse. 
Watching the babies grow has been an absolute treat this winter. Be sure to come visit to see these youngsters before they're all grown up!

Appreciate a Dragon!

From Europe to Asia, the dragon has deep mythological roots in many cultures. Usually depicted as a serpent-type animal that’s able to breathe fire, the image was enough to strike fear into the heart of societies for generations. At the New England Aquarium, however, we take a different approach to these mythical creatures!


Visit the Australian Temperate Reef exhibit on the second floor and look closely. Do you see them? They may not be breathing fire, but the Aquarium’s sea dragons are just as awe-inspiring as their mythical counterparts! With their leafy appendages and slow movements, they completely blend into their environment. And those long snouts are perfect for catching small plankton as it drifts by.



Many visitors comment the sea dragons resemble sea horses…and for good reason. They are close cousins, part of the family of fishes called Syngnathidae. And like their cousins, sea dragon males are responsible for most of the reproductive responsibilities.


Male sea dragons will take care of the eggs while they are incubating, just as male sea horses do. However, instead of holding the eggs in an abdominal pouch, sea dragons collect the eggs and keep them in a spongy brood patch near the base of their tale. And with the female laying 250 to 300 eggs, that’s a lot of little ones to worry about!

Once ready to lay her eggs, the female will push the fertilized eggs into the soft skin of the male tail. The skin becomes hardened, forming a cup around each egg that secures it during incubation. After approximately six to eight weeks, the young sea dragons hatch a few at a time and float away to start life on their own! They do grow fast, reaching full size in approximately two years when they could potentially have young of their own.

Only a handful of aquaria world-wide have been able to hatch sea dragons successfully, as it is extremely difficult to do. And while we haven’t had any young here yet, we do have great success showcasing our two species of sea dragons and have our fingers crossed that we may have some young in the future. Since today is Appreciate a Dragon Day…what better way to appreciate dragons than to come to the Aquarium and get inspired with these amazing, but not so mythical, creatures!

Baby Fish! Meet the Newest Gulf Stream Orphans

Don't miss seeing these baby fish during school vacation! Buy your tickets online now.

They may not be warm and fuzzy, but you'll feel warm and fuzzy after seeing the new babies in the Yawkey Coral Reef Center. And if you haven't been bowled over because of all the cute, these baby boxfishes will endear themselves to you once your hear about their journey.

Educator (and frequent blogger) Jo Blasi snapped these pics of the ├╝ber adorable baby cowfish. So much cute!

Boxfishes are common sights on reefs in Florida and the Caribbean, but this particular duo—a trunkfish and a cowfish—was collected this past summer by the Aquarium and Biomes Marine Biology Center staff and volunteers in totally-not-tropical Rhode Island! They are what we refer to lovingly as “Gulf Stream orphans” — a.k.a. tiny reef dwellers that get caught up within the current of the Gulf Stream and cannot escape until they’re swept up north to New England.

During the summer and early fall months they can live in the bays and inlets where water temperatures are often in the mid-sixties to low-seventies. Under collection permits issued by the state, Aquarium staff and volunteers head to Rhode Island every summer and fall to dive and seine for these young tropical fishes. This is a rescue mission of sorts because while these fishes can survive up north in the warmer months, they certainly would succumb to the colder water temperatures once winter settles in.



When we collect on our expeditions in the Bahamas, we make sure to visit a wide range of diving sites in order to minimize our impact on the breeding populations on the reefs. These Gulf Stream orphans would never have been able to travel back down to Florida or the Caribbean, so once they’re swept up here they are completely out of the potential reproductive population for that species. Increasing our efforts the past few years to collect Gulf Stream orphans is just another way the New England Aquarium is working towards even more sustainable animal collection practices.

Spot the seining net on the beach with other equipment needed to transport the wayward young'uns.

When collecting in Rhode Island the easiest species to spot while diving are the spotfin butterflyfishes. Bright white and yellow, they dart from rock pile to rock pile close to the shore. Catching them is a whole different story. Aquarists work in teams of two or three to surround these tiny fish until they can get close enough to guide them into their collecting nets. Boxfishes are often only found when seining in seagrass beds along the shore.

The Gulf Stream orphans are transported back to our offsite facility in Quincy. The fish receive the same attentive care that they do on Central Wharf as they go through routine quarantine treatments and get regular check-ups by our vet staff. And then it's eat, eat, eat until they are large enough to to go onto exhibit.

After a quick ride on the Southeast Expressway, fishes like the cowfish and trunkfish can be added to several different exhibits at the Aquarium home. In addition to these boxfishes and butterflyfishes in our Yawkey Gallery, you can find other Gulf Stream orphans all around the Aquarium.

In the Blue Hole exhibit keep your eye out for these Gulf Stream orphans, the short bigeye,
 a bright red, stout fish with large round eyes.

When they get large enough to fend for themselves, many of these Gulf Stream orphan species, such as snowy groupers, scamps, bandtail puffers and spotfin butterflyfish can, be found in the Giant Ocean Tank. These little fish grow up fast, too! So get yourself to the exhibits at the top of the G.O.T. to see these baby fish before they grow up!

Cowfish have horns, trunkfish do not

Captivating Camouflage [Seadragon GIFs]

For your daydreaming pleasure, please enjoy these leafy seadragon gifs.


And now that we have your attention, how about some seadragon fun facts. Did you know seadragons are a temperate species? They are not the delicate tropical flowers they seem. The water in their tank is a brisk 58–62˚! Brrrr.



The leafy and weedy seadragons have tiny mouths that open rapidly to suck in their prey. And they are very particular about that prey, in fact—only mysid shrimp is on the menu.



These slow-moving animals rely on those fluttering decorative appendages for camouflage only. To get around, albeit slowly, they use the clear dorsal fin that you see undulating on their back. They also have two smaller fins on either side of their neck.

Leafy seadragon

There are only three species of seadragon on the planet—two of which you can see here at the Aquarium. The leafy (seen here in gif-fy glory) and the weedy are on display in the Seadragon Exhibit of our Temperate Gallery. The third species is the recently-identified ruby seadragon.

Try spotting them among the habitat in their Level 2 exhibit here at the Aquarium. And if you cannot get enough seadragons, check out aquarist Jeremy Brodt's expedition blogs from his trip to seadragon country in Australia.
