4 Secrets of Blacktip Reef

Even if you spent a full day in the National Aquarium's Blacktip Reef exhibit, you would never learn all the fascinating facts about its many animals, which range from blacktip reef sharks and tasselled wobbegongs to clown triggerfish and honeycomb stingrays. But thanks to these insider secrets provided by our knowledgeable staff and volunteers, you're about to know more than most visitors.

1. Our blacktip reef sharks are longtime buddies.

One of the unique characteristics about blacktip reef sharks is their camaraderie. These big fish often swim in schools in the wild, and our school of blacktip reef sharks are no different. They lived together in our Animal Care Center for 18 months before moving into their new home in Blacktip Reef, giving them plenty of bonding time before the big day.

2. Our tasselled wobbegong shark has a secret hiding place.

The tasselled wobbegong shark is tricky to spot—its ornate camouflaged exterior is easily mistaken for a piece of coral. But if you look closely at the left corner of our underwater viewing area, you're likely to notice her resting in her favorite spot near the glass.

3. The coral reef isn't made of real coral.

Real barrier reefs can take 100,000 to 30 million years to fully form, so growing our own coral wasn't an option. Instead, we painstakingly crafted our own—all 3,000 pieces of it—from the molds of real coral skeletons. Now it serves as colorful shelter for our diverse array of Indo-Pacific fish.

4. Zebra sharks are spotted, not striped.

The zebra sharks found in Blacktip Reef don't appear to have stripes at all, but that wasn't always the case. As juveniles, zebra sharks—often mistakenly called leopard sharks—have dark bodies with yellowish stripes. This pattern transforms into small dark spots on a grayish-tan background as they age.
