A crab for the cuttlefish

A beautiful broadclub cuttlefish is currently stalking our cuttlefish exhibit. It is fed an assortment of seafoods, including live crabs now and then. Recently a staff member had their phone recording video during afternoon snack. Take a look at this cool behind-the-scenes video!


[Check out our Behind-the-Scenes Tours if you want another perspective on our exhibits—like this one.] 

While it takes about a half-hour to eat a fish, it may take the cuttlefish more than an hour to devour the crab because of its crusty exoskeleton. The aquarist usually find only the carapace and a few legs after the meal.

The way cuttlefish capture their prey is pretty fascinating to watch, too, but it happens so fast! We actually have some spectacular slow-motion footage that shows exactly how a cuttlefish (a common cuttlefish, in this case) nabs its meal. Watch how this cunning cephalopod captures its food with two retractable tentacles, then pulling it into the grasp of eight waiting suction cupped arms.



This footage was taken by photographer Keith Ellenbogen at 500 frames per second, about 17 times slower than it occurs to the naked eye. A typical video camera records at about 30 frames per second.

With your new appreciation for cuttlefish, look for these invertebrates in their Level 1 exhibit here at the Aquarium. Whether they're changing color or hunting, they never cease to amaze!

An Anemones Breakfast

This morning in the Pacific tidepool exhibit it looked like sea star was on the menu.

Spotted in the Northern Waters Gallery
Giant green anemones are sessile creatures, meaning they remain mostly fixed to the sea floor by a smooth, muscular disk. That disk can move about very slowly so these animals often feed opportunistically on fish, crabs, and sea urchins that come their way. Looks like this sea star got a little too close to those stinging tentacles.

It just goes to show you that you never what you'll find at the Aquarium—and in the wild. Last year, photos of a green anemone digesting a cormorant circulated around the internet.

Cool stuff, right? Here are some other links you might enjoy:

Feeding Time: Shark and Ray Touch Tank

How do you feed a shark or a stingray? Very carefully! That’s a joke that we hear (and tell) a lot at the Trust Family Foundation Shark and Ray Touch Tank. And while it might be a joke, feeding our animals is something we take very seriously at the Aquarium!

Everyone looks forward to breakfast!

The topic of feeding (and eating!) comes up a lot throughout the Aquarium. It makes sense—eating is one of those universal things that all of us organisms need to do. With over 100 animals in the touch tank, visitors often are curious to learn how we feed so many animals in one place.

The first question many people ask is what do we feed the animals in the exhibit. Fortunately, all of the different species of sharks and rays eat the same types of food. So what’s on the menu? Mealtime usually includes squid, small fish, clams and shrimp. The diet is prepared first thing in the morning and then fed to the exhibit throughout the day.

Breakfast!

As feeding time arrives, food is simply scattered on the sandy bottom of the exhibit. Both sharks and rays will cruise over the sand, picking up pieces of food as they go. To ensure that everyone has the opportunity to get something to eat, the exhibit has food added to it a couple of times a day. But the animals never know when it’s coming—we change the times slightly each day to keep them guessing!

Making sure everyone gets something to eat

Food sinking to the bottom

As the food sinks to the bottom, animals come from all over the exhibit to the two main sandy areas. Even those animals that usually hide during the day, including the sharks, will come out for a snack! In a flurry of fins, tails, and mouths, the food is gone in no time!





With a keen sense of smell, these animals can locate their prey easily. And as their mouths are located on, or near, the bottom of their body, scooping up food from sand is no problem. Both the rays and sharks will eat when they are hungry, so it's possible that every animal might not eat at each meal. But with feedings happening throughout the day, everyone has the opportunity to find a yummy snack when they want one.

Perhaps next time you visit the Aquarium, you might just be in time to see the shark and stingray touch tank exhibit animals get something to eat. Consider buying your tickets online and printing them at home so you can zip in the door when you arrive. Here's where to start planning your next visit!

And in case you're hungry for a snack of your own, head over to the New England Aquarium's website for environmentally friendly seafood options and seafood recipes. Bon appetit!

Goosefish Feeding Time…in Slow Motion!

Goosefish

When people first approach the goosefish exhibit, many visitors have a hard time finding her in the tank. The goosefish is perfect at blending into the seafloor with her gray color and a flattened body shape. And when it’s time to find food, this appearance has a lot of advantages!

Can you find the goosefish?

Goosefish are opportunistic feeders and will eat anything that comes near their oversized mouths, including fish, birds, shrimp…even soda cans! By blending in, the chances of a food item swimming close to the fish increase. The goosefish will lie on the seafloor, wait for something to get close and then, with a quick burst of speed, engulf the whole item with its mouth. Check out this slow motion video of our goosefish eating!



To help draw prey closer, goosefish have what looks like a fishing pole with a lure on the top of their head. They use this modified fin to ‘fish’ for their food. By waving it up in the water, the small lure resembles a small fish or a worm and attracts larger fish, such as silversides, closer to the goosefish. Once that happens, it’s lunchtime for the goosefish!

The goosefish's modified dorsal fin acts as a fishing lure.

The shiny fish in the exhibit, called silversides, are not her food (the aquarists provide her with healthy meals on a special feeding tool) but provide the goosefish with behavioral enrichment. By having the silversides near her, the goosefish gets a chance to practice her fishing skills.



In addition to her ravishing beauty and impressive fishing skills, the goosefish has another noteworthy accomplishment: Each year she wows visitors with her egg veil. This year our aquarist caught video of her laying the egg veil! See more pictures and video of the egg veil.

So the next time you visit our Gulf of Maine exhibits, stop by and check out the goosefish. If you are lucky, you might be able to see her fishing! And while you're in these chilly Northern Waters galleries, don't miss the octopus and green anemone tidepool exhibits.

A Sucessful Anaconda Feeding

Warning: Contains pictures of a snake eating.

Ashley and Kathleen are offered food every Saturday in the early afternoon. (Usually between 1 p.m. and 2 p.m., so if you're around the Aquarium come check it out on the third floor.) Lately, however, neither snake has been eating. I suspect both girls of being pregnant, which can throw off their internal rhythms, and anacondas have been known to have long fasts.

This past Saturday marked 19 weeks of fasting for Kathleen. However, Ashley broke a 7-week fast that included two shed cycles on Saturday August 29th and she ate again on Saturday September 5th.

Ashley takes a guinea pig.

She's almost done swallowing.

We feed our snakes frozen (then thawed) food from a mail order supplier of frozen rodents. This is less stressful for the staff, because we all love animals in this job. It is also better for our snakes. Live food can fight back with teeth and claws and injure the snakes.

Welcome to our Shorebird Exhibit!

Welcome to the New England Aquarium's shorebird exhibit "In on the Wind: shorebirds and the Boston Harbor Islands".


You're about to enter a unique exhibit featuring many different species of fish, plants, invertebrates and birds all living together. Peer through the mesh and you will see, and hear, six species of shorebirds. A common tern, two sanderlings, a dunlin, a virginia rail, two semipalmated plovers and two threatened piping plovers can be seen foraging for food amongst the rocks, marsh grass and driftwood and sometimes even in the saltwater pool itself! Press play and watch as our sanderlings catch crickets!



Look through the glass into the pool and you will see a large school of mummichogs, silversides and sheepshead minnows darting in and out of the kelp and irish moss. Bright orange finger sponges grow off the sandy bottom where four winter flounder hide with only their eyes peering out. Hermit crabs check out empty periwinkle shells looking for a housing upgrade. If you're lucky you'll see one of the elusive decorator crabs as he makes his way around the tank "decorating" himself by gluing sponges, pebbles and bits of seaweed to his shell. Play the video below and watch as the tataug comes out of the seaweed on the left, takes a bite out of the sponge, and returns to his lair.





Please come and visit again and you will have the chance to meet our birds one individual at a time, hear their mating calls, see where they nest and watch as they migrate through the harbor in the thousands! Thank you for visiting!
