Pacific Reef Community: Meet the cast

There's a certain, beloved Disney movie that almost always comes up during a visit to the Aquarium. In particular, there's a lot of finding in the Tropical Gallery on the first floor. You know what we're talking about. Yup, Finding Nemo! And you can see three species from the movie in the vibrant Pacific Reef Community.

First up, the distinctive stripes and bright orange color of the clownfish! There are a couple species of clownfish in this exhibit, but it's the Ocellaris clownfish (Amphiprion ocellaris) that folks will recognize as Nemo. These are smaller fish that will grow to be only a couple inches long, at the most. And it's obvious that these little guys are on the smaller end of the spectrum in this exhibit.

Look closely! The clownfish usually hide out along the back of the exhibit toward the right.
But some folks have been able to get up-close and personal with these fish during a
 Behind-the-Scenes Tours

While clownfish in the wild (and the living coral exhibit) usually make a home in an anemone, this pair has carved out a small territory where they feel safe. Look for them at the far right side of the exhibit, along the back wall (see picture).

Next, Nemo's dad's good buddy Dory—the palette surgeonfish (Paracanthurus hepatus).

There are around eight of these royal blue beauties in the exhibit. They can grow to be about a foot long with a thin, pancake-like body shape. The name surgeonfish comes from the sharp scalpel-like spine at the base of their bright yellow tail. It's a defense mechanism. They can turn-tail and slice at threats, inflicting a deep wound with their sharp caudal spine.

Look for the palette surgeonfish cruising quickly back and forth across the exhibit, nibbling algae from the fiberglass corals or snacking on plankton in the water.

Last from the cast of Finding Nemo in the Pacific Reef Community, look for the one Moorish idol (Zanclus cornutus) cruising the reef. (Not to be confused with the pennant bannerfish, more on that black and white striped fish later.) This handsome fish of black, white and yellow has a distinct long, flowing dorsal fin and a puckered mouth.

There's a full spectrum of colors, patterns and behaviors streaming through the Pacific Reef Community on the first level of the New England Aquarium. Transport yourself to far-away reefs, where you can appreciate how life inspires art.

Making a home in the Sea of Cortez

Anyone who's visited the Aquarium recently has likely noticed our colorful new Sea of Cortez exhibit on the first floor. If a visitor paused a moment, they may have seen this fascinating little fish doing a little excavating.

Blue spotted jawfish surveys the exhibit from his burrow in the Sea of Cortez exhibit

Bluespotted jawfish (Opistognathus rosenblatti) build their burrows by scooping sand with their large mouths and spitting it out the entrance of the nest. While they do venture out of their burrows to feed on invertebrates in the water column, they are quick to dart back inside when threatened. Check out this short video clip to see the jawfish in action.



The jawfish is just one of several interesting species living in the Sea of Cortez exhibit. This beauty — a Moorish idol (Zanclus cornutus) — is the only known member of its taxonomic family. The name is purportedly derived from the an ancient belief that they bring happiness to those who encounter them.

The Moorish idol is one of the handsome residents of the
Sea of Cortez exhibit on Level One.

And then there's the gold-rimmed tang. Learn more about its territorial spinning behavior in this previous post. Plus the Cortez rainbow wrasse, the keyhole angel, and the list goes on. There's also a whole other marine habitat in this exhibit, too — a deep Pacific coral environment. See a video of this display here.

The Sea of Cortez, also known as the Gulf of California, is a special corner of our marine world. As one of the most biologically diverse marine areas in the world, it was inscribed as a UNESCO World Heritage Site in 2005. (The Phoenix Island Protected Area was named a World Heritage Site this year! Learn more about this Pacific Ocean marine protected area that the Aquarium helped create on the PIPA Blog.) Come on down to the Aquarium to glimpse a slice of this vibrant ocean habitat right here in Boston!
