All animals have their favorite foods, just like people do. This Thanksgiving, while humans are filling up on turkey and stuffing, these species want tasty treats like mice, crickets, crayfish and even sea monkeys.

You can see these animals and more when you visit Greater Cleveland Aquarium. Check out the Aquarium’s See & Do page for a chance to see some of these species and others dine on their favorite snacks.
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 Sturgeon – Check out that shovel-shaped snout.
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 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.

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.

Sometimes reputation is not reality. Greater Cleveland Aquarium’s Education team takes a quick looks at snakes, piranhas and sharks to see if they’re really “bad guys” or just misunderstood.
SNAKES
Snakes have been portrayed as bad guys across the globe for centuries. Ancient Greeks share the myth of Medusa with her head of snakes turning humans to stone. Christianity writes about snakes representing evil and temptation in the garden of Eden. Ancient Egyptians tell of a two-headed serpent guarding the underworld.
Paired with the fact that some snakes deliver a venomous bite, it is not surprising that many people dislike or even fear snakes. However, with more than 3,000 different species of snakes on the planet, there is much to celebrate as well. Less than 7% of snake species are able to significantly harm a human. Snakes play an important role in keeping rodent pest populations under control. Many snakes are both predator and prey in an ecosystem food web, so losing them would have a negative affect on many other species.
The snake at the Aquarium is a green tree python. She spends a significant amount of time curled up on her branch, basking in the humid, tropical temperatures. She starts her life as a different color entirely and becomes a brilliant green color as an adult.
If you encounter a snake, you should give them space, but there is no reason to harm it.
PIRANHAS
The piranha’s negative reputation can be traced back to Theodore Roosevelt. He witnessed a staged feeding frenzy of starved piranhas on a trip to South America and wrote about the experience. More than 120 years later, these fish are still working against that tale. The 1978 movie Piranha showcasing a piranha hunting humans refueled the hype, as it showcased piranha hunting humans.
In reality, humans are not part of a piranha’s food chain. Many piranha feed on smaller fish species, and some are omnivores, eating both meat and plant material. In the scientific community, they are described as timid scavengers. Piranha group together for safety to protect themselves from their own predators, like large birds.
The piranha at the Aquarium are red-bellied piranha. They can be admired for their shiny scales. They are an important part of their ecosystems in freshwater rivers of South America. Piranha should be more appreciated than feared.
SHARKS
Sharks are often portrayed as villains in movies. Jaws, Sharknado, The Shallows, The Meg and even The Little Mermaid portray sharks in a negative light. While some sharks are large, and some do have sharp teeth, there is way more to appreciate about sharks than to fear.
Sharks are apex predators. At the top of the food chain, they play a crucial role in keeping the ocean ecosystems in balance, but humans are not part of the menu. There are more than 400 species of sharks and they eat a variety of different types of foods, with the largest whale sharks eating krill, and the smallest dwarf lantern catching tiny prey with an alluring bioluminescent light.
The sharks at the Aquarium are sandtiger, sandbar and nurse sharks. A fan favorite of Aquarium guests, it can be quite calming to watch them swim slowly through the water.
You are more likely to be struck by lightning, fall off a cliff taking a selfie, or be killed by a lawnmower, than be attacked by a shark. Sharks should be revered rather than feared.

Greater Cleveland Aquarium is proud to announce the arrival of newborn weedy sea dragons, a species that has proven to be exceedingly difficult to rear. Since the first successful weedy sea dragon hatching in 2001 at the Aquarium of the Pacific, fewer than 20 facilities worldwide have had any level of success with mating and only an estimated dozen of those have had fry survive.
A delicate species whose survival has been tested by habitat degradation, weedy sea dragons are native to the cold coastal waters of south and west Australia.
“Weedy sea dragon births are exceedingly rare, and this would be a point of pride for any animal care facility, but it’s a particularly exciting for an aquarium of our size and age,” says General Manager Stephanie White, who has been with the downtown Cleveland destination since it opened a decade ago in January of 2012.
Greater Cleveland Aquarium is housed in a brick building dating back to 1892, and Curator Ray Popik believes the creativity required to reimagine the historic space contributed to his team’s success breeding sea dragons. “We were able to home the sea dragons in a very deep exhibit built into a structure that likely served as an air duct or a coal chute when this building was an operational powerhouse,” says Popik, explaining, “Its depth provided an optimal habitat for the seahorse relatives who court with an elaborate vertical dance.”
After a female weedy lays her eggs, they are transferred to the male who, similar to its pipefish cousins, is then responsible for fertilizing and carrying them until they hatch. “This was actually the second time one of the female sea dragons in our care deposited eggs on a male’s tail,” says Popik.
While the initial egg transfer in January of 2020 was likely too early in the Aquarium residents’ development to result in viable offspring, the initial mating and successful deposit was an indication that the sea dragons—who came to the Aquarium in March 2018—were thriving. “Animals need to be healthy, have good nutrition and be acclimated to mate,” explains Popik. “We felt the odds they would try again were good.”
A second mating attempt in September of 2021 resulted in another clutch of eggs and fry popping out between late-October and the beginning of November. The hatchlings were moved behind-the-scenes. “There’s no parental involvement after birth and it’s incredible that any of these tiny offspring survive when they’re left to fend for themselves in the ocean,” says Mallory Haskell, the primary aquarist responsible for their monitoring and delicate care. Not particularly strong swimmers, weedy sea dragons’ leaf-like appendages blend in with kelp and seagrass help hide them from predators.
Greater Cleveland Aquarium plans to put some of the young on public view soon in a temporary exhibit just down the corridor from the adult weedy sea dragons. “It’s been amazing to watch these animals develop and we want to give that opportunity to others if we’re able,” says White.
The process has been full of ups and downs, but Haskell is optimistic. “If raising weedy sea dragons was easy, everyone would do it,” she says. “We know there are challenges ahead, but we hope we will see a number of these sea dragons reach full size in a year or so.”
When mature, green tree pythons spend a lot of time in trees, often resting their diamond-shaped heads over one or two coils they’ve looped over branches to create a saddle. Here are five other facts about these arboreal snakes:
There’s a lot more to learn about this nonvenomous snake that can be found in Indonesia, New Guinea and Cape York in Australia. You can see this one in the Asia & Indonesia Gallery at the Greater Cleveland Aquarium. Nature. It’s a curious thing.

This whiskered, bottom-dweller generally measures 15-25 inches in length, but it can get bigger. Here are 5 other facts about the channel catfish.
These catfish are most active at night. They are also found to be out more often after rain.
Like other catfish, the channel catfish has no scales. It has sharp and deeply serrated spines on the dorsal and pectoral fins. Sometimes when caught, people are often “stung” by the spines on their fins.
Adult channel catfish consume fish like yellow perch and sunfish as well as snails, algae, snakes, frogs, insects, plants and even birds. At the Aquarium, they often enjoy chopped frozen fish like shiners, minnows and silversides, as well as a prepared gel food—think fish Jell-O—as well as a wide variety of pellet food.
Thanks to the Weberian apparatus, which connects the swim bladder to the ear, they are able to amplify vibrations coming from the swim bladder. This gives the channel catfish great ability to hear what is going on in their surroundings.
Channel catfish can live in fresh, brackish, and even saltwater, but they are generally found in freshwater environments, just like the lakes, ponds and rivers right here in Ohio.
You can take a closer look at the channel catfish and other large Ohio gamefish in the Ohio Lakes & Rivers Gallery at the Greater Cleveland Aquarium.

Think about spiders, piranhas, or snakes. Simply the sound of some animals’ names causes fear and panic. Whether it stems from tall tales or a few chance encounters, unfortunately for the animals involved, bad reputations developed over time tend to stick. Sharks might be the ultimate example of this situation. There have been many movies about sharks made over the years. A recent study from the University of Australia asserted that “almost all of these films (96%) overtly portrayed shark-human interactions as being potentially threatening to humans.” How factual and accurate have these movies been to sharks? Let’s take a closer look at a few of them.
In Jaws, Amity Island was terrorized by a Great White shark that ruined quite a few people’s vacations and the blockbuster film’s protagonists indeed ended up needing a bigger boat to catch this predator. Jaws had such an impact on our collective psyche that the reputations of Great Whites and other shark species remain affected by the movie to this day—46 years after the motion picture came out. The big myth in Jaws is that sharks specifically target humans. In truth, we simply are not on a shark’s menu. Rarely do humans and sharks come in contact, but IF they do, sharks mistaking a person for a seal or another one of their actual prey items might take an exploratory bite before quickly realizing the mistake and swimming off. A vengeful, human-seeking shark like the Great White in Jaws doesn’t occur in our oceans.
Many shark movies since Jaws have leaned into a more fictional sci-fi component, such as Deep Blue Sea, The Meg and, of course, all the Sharknado films. (They apparently made six so far?!). I hope I don’t need to let you know that no one needs to fear long extinct predators, DNA-altered sharks or waterspouts causing sharks to attack humans in the sky and on land.
But there are some movies that could seem very realistic to the average movie fan, such as The Shallows. This film finds an injured young surfer fighting for her survival in the open water while the Great White shark that bit her circles and zeroes in on its compromised target. Similarly, to Jaws, this movie portrays the shark to be following a prolonged plan of attack on our species, although on a smaller scale. Sharks don’t spend extended periods of time playing this cat-and-mouse game with prey. Many sharks like the Great White must be swimming constantly to breathe, and sharks are too smart to waste time and energy for very long before moving on to the next area or potential meal.
It’s important to know that we are not telling you to never watch another shark movie ever again. I love all kinds of movies and I know these thrillers can be fun to sit down and enjoy. We just ask to do your best in not letting television and movies fully form your opinion of animals like sharks. As apex predators, sharks are extremely important to the health of the oceans on which humans rely heavily. It’s vital that we are constantly trying to improve the public opinion of sharks for their overall conservation. A third of all shark species are threatened or endangered, and movies have done their part in contributing to the decline. Going forward, we need to try and continue to flip the narrative on sharks, talking about them in a positive way and focusing on the facts to protect them as a species and ultimately protect our oceans.
