5 Things I Learned About the Brownbanded Bamboo Shark

July 11, 2024
 / 
Written by

Found around coral reefs and sandy, muddy-floored habitats, brownbanded bamboo sharks are a smaller species coming in at only 2.8 feet long on average. Here are 5 things a non-aquarist learned about this fascinating animal at Greater Cleveland Aquarium.

  1. Brownbanded bamboo sharks change color as they mature—juveniles maintain a medium-brownish color with dark banding, while adults appear solid brown. They’re estimated to live around 25 years.

  2. These sharks dine on smaller fare, like crabs, small fish, shrimp and bristle worms. Their own predators include larger fish and even other sharks.
  3. Brownbanded bamboo sharks are largely nocturnal, spending most of the daytime hiding in small spaces in the reef. After dark, they come out to hunt.
  4. Brownbanded bamboo sharks lay eggs in elongated cases. Given their smaller stature, it’s no surprise newborns are only 5 – 7 inches long when they hatch.
  5. Surprisingly, this species of shark can tolerate hypoxia—low oxygen levels—for up to 12 hours. This adaptation helps them survive low tides in the shallow pools where they’re often observed. Could you hold your breath that long?

Look for this interesting shark, as well as—sandtigers, sandbars and Atlantic nurse sharks—during Fin Fest (Now – Tuesday, August 6) at Greater Cleveland Aquarium. Nature. It’s a curious thing.

5 Things I Learned about the Sandbar Shark

Sandbar sharks, like the one you see here, reside within shallow coastal waters around the globe—ranging from Massachusetts all the way to Brazil in the Western Atlantic. Here are 5 things a non-aquarist learned about this interesting animal at Greater Cleveland Aquarium.

1. This species of shark is considered an opportunistic bottom feeder. From small fish and crustaceans to octopi and stingrays, sandbar sharks don’t leave much off the menu.

2. The only predator of sandbar sharks are—can you guess?—other sharks! Juveniles will sometimes fall prey to larger species like bull sharks, otherwise there are few animals interested in hunting them.

3. Sandbar sharks only breed every 2-3 years and live anywhere from 25 – 30 years old. Researchers estimate full maturity happens around 13 – 16 years of age, meaning they reach true adulthood around the time you first learned to drive!

4. In 2020, the International Union for Conservation of Nature classified sandbar sharks as endangered, citing a 50 – 80% decrease in population over the last 75 years. However, management plans have been put in place and those regions are seeing populations begin to stabilize in the shallow waters they call home.

5. Sandbar sharks migrate seasonally, with juveniles often moving from shallow coastal waters to warm deep waters. Interestingly, males tend to migrate in large schools, while females make the journey solitarily with no company.

Look for sandbar, sandtiger and other species of sharks during your next Greater Cleveland Aquarium visit. Nature. It’s a curious thing.

What Does Parenting Look Like in Nature?

Ever wondered what parenthood looks like when it comes to the animal kingdom? From mouthbrooding to live births, parenting takes many different forms depending on the species. Here are a few interesting examples among the animals you might see on your next Aquarium visit:

Box Turtles

Box turtles are an egg-laying animal. After breeding, the female will bury the eggs on shore, leaving them to hatch and fend for themselves. Did you know the temperature of the environment where the eggs are laid determines whether they emerge as male or female?

///

Black-Naped Fruit Doves

This species splits parenting responsibilities between the male and female, with each bird taking turns looking after the nest while the other forages. That vigilant care is important, as the female often lays just a single egg that needs 18-26 days to incubate.

///

Surinam Toads

Fun fact, Surinam toads are actually frogs despite their misleading name. Their intrigue doesn’t end there—these frogs have a particularly interesting reproduction cycle. After breeding, female Surinam toads embed the eggs on their backs and carry them until they hatch. Instead of tadpoles, offspring emerge as fully metamorphosed little frogs.

///

Cichlids

Cichlids like this red-striped eartheater are mouthbrooders—this means they carry their offspring in their mouths until they are mature enough for independence. It may look strange to humans, but these fish will let their offspring forage for food before sucking them back up if the parent feels threatened. This close-quarters parenting gives offspring a better chance of survival.

///

Stingrays

One of just a few animals that give live births at the Aquarium, stingrays like the one above will carry their young for 11-12 months. Most of the time they give birth to just one pup, who is then left completely independent. While it takes a bit longer for the pups to fully mature, they enter the world with a fully formed barb ready to deter any possible threat.

While the giant Pacific octopus or sandtiger sharks always make an impression on Greater Cleveland Aquarium guests, many little animals are capable of doing mighty things, often impacting their ecosystems in invaluable ways. Check out few examples of a few smaller species worthy of your appreciation on your next #cleaquarium visit.

Stoplight Parrotfish

Parrotfish jaws and teeth are uniquely adapted for eating corals. Their strong teeth can crush up the hard coral skeleton and once it passes through the fish’s digestive system it is expelled as sand. It is estimated that parrotfish produce as much as one ton of coral sand per acre of reef in year.

Scarlet Cleaner Shrimp

Cleaner shrimp set up cleaning stations on top of a rocks or coral, almost like underwater car washes. Once the cleaner shrimp sway side to side to signal they are “open for business,” fish drop in to have their dead cells and parasites removed.

///

Cookie Dough Sea Cucumber

Cookie dough sea cucumbers interact with their environment almost like an earthworm in soil, breaking down small particles in the water that contribute to the nutrient cycle.

Eastern Musk Turtle

Found in the Eastern and Central United States, these little turtles are sometimes called stinkpots for the big smell they produce to deter predators.

Northern Clingfish

The clingfish is unique in its ability to quickly attach and detach from wet, irregular surfaces. Their suction disk can cling so tightly that scientists are trying to create suction cups based on the clingfish’s disk’s functionality.

When they’re ready to mate, male Solomon Island leaf frogs emit a barking sound to attract a female. When their brood is ready, the eggs hatch as fully formed frogs, with no tadpole stage for this species.

///

Red-Bellied Piranha

Red-bellied piranhas swim in circles to attract mates. The eggs are then placed in bowl-shaped nests and hatch in just nine to 10 days.

///

Red-Eared Slider

How animals earn their monikers can be surprising. Their common names can come from the places they’re found, the people who discovered them or even fictional characters. The names of the ten Aquarium residents below are inspired by their appearance and/or actions.

 

shovelnose sturgeonShovelnose Sturgeon – Check out that shovel-shaped snout.

 

Red-eared slider turtle.Red-eared Slider – This turtle is named for the red patch on its ear AND the way it slides into the water when startled.

 

Clown Knifefish – This fish’s knife-like shape allows it to swim both forwards and backwards.

 

Crystal-eyed Catfish – Frank Sinatra might have been “ol’ blue eyes,” but this catfish gets attention for its light blue peepers.

 

Dyeing Poison Dart Frog – This name comes from an unverified legend that indigenous people used these colorful frogs to dye parrot feathers.

 

picasso triggerfishPicasso Triggerfish – This peculiar-looking fish has bright, artsy colors AND a dorsal spine will raise when startled.

 

Hammer Coral – Note the hammer shape of these coral polyps.

 

Scrawled Cowfish – The “horns” above its eyes and irregular body markings are what give the scrawled cowfish a distinctive appearance.

 

Raccoon Butterflyfish – This butterflyfish is named for the black-and-white “mask” around its eyes.

 

Black Drum – This fish can make drumming or croaking sounds with muscle movement around its swim bladder.

Small Animal Feedings

During Spring Discovery Days, Greater Cleveland Aquarium focuses on the little things. That’s why created a series of short “mealtime” videos featuring some of smaller residents.

In this one, Aquarist Bethany gives the Surinam toads one of their favorite treats . . . earthworms. 

Here’s cellphone footage of Aquarist Seneca feeding an animal you might spot in Northeast Ohio parks . . . the yellow spotted salamander.

Sea stars eat in a way you might find odd. They extend their stomachs out of their mouths and envelop their food. Aquarist Katie fed a Bahama sea star and we sped up the video so you could watch this process. The food is partially digested externally, and eventually the sea star will pull its stomach back in through the mouth.

And here’s cellphone footage of Lando feeding frontosa, black piebald and daffodil cichlids.

Hungering for more? You never know what you’ll see when you visit the Aquarium.
