5 Things I Learned About Picasso Triggerfish

December 12, 2024
 / 
Written by

Known for its bright, distinctive bands of color reminiscent of a Pablo Picasso painting, you’re looking at the aptly named Picasso triggerfish. Here are 5 things a non-aquarist learned about this fascinating species at Greater Cleveland Aquarium.

1: Some know this species by a different name: lagoon triggerfish. Another fitting title for a fish that spends most of its time
in sub-tidal reef flats and shallow lagoons.

2: For breeding, this species forms distinct pairs. Females build the nest before laying eggs and become very territorial as they guard their future young.

3: Because of the shape of the dorsal and anal fins, this species can swim forwards, backwards and even hover in place.

4: When alarmed, the triggerfish makes a whirring sound. Researchers believe the whirring warns other triggerfish of potential danger.

5: The “trigger” in triggerfish comes from their dorsal spine, which can be raised when startled. If the fish is hiding in a small space, the spine acts as a wedge to hold them in place.

With its bright coloration and attention-grabbing name, it’s hard not to notice the Picasso triggerfish. Look for one during your next Greater Cleveland Aquarium visit.

 

5 Things I Learned About Northern Clingfish

Written by

This flat, round animal is the Northern clingfish, typically found in in the Eastern Pacific from Alaska to Mexico. Here are 5 things a non-aquarist learned about this fascinating species at Greater Cleveland Aquarium.

1: With a slightly flat, depressed head, the clingfish’s pelvic fins connect to form an adhesive disk, which it uses to stick itself strongly to rocks and plants. Just to hammer home how impressive their physiology is, scientists are currently in the process of creating suction cups inspired by the northern clingfish’s disk.

2: Clingfish use their suction to steady themselves as they pull prey off rocks. Their favorite menu items include crustaceans and mollusks.

3: In terms of their predators, clingfish have to keep an eye out for snakes, gulls and even raccoons, who might snatch them up at low tide!

4: Northern clingfish reproduce by laying eggs under rocks. The eggs hatch into what are called platonic larvae and it’s the males who protect the babies.

5: A northern clingfish can survive low tide by breathing air—well, more like it absorbs oxygen through its skin, which is a useful trait for an intertidal fish.

Look for this interesting fish clinging to the glass or rocks of its habitat during your next Greater Cleveland Aquarium Visit. Nature. It’s a curious thing.

8 Things We Now Know About Sharks & Rays

July 16, 2024
 / 
Written by

The ocean covers 70 percent of the Earth’s surface. According to NOAA, just 26.1 percent of the global seafloor had been “mapped with high-resolution technology.” Clearly, there’s a lot we don’t know about these vast, deep waters and their inhabitants. With hundreds of different identified shark and stingray species, we still have so much to discover! Here are eight shark- and stingray-related findings that have made the headlines in the 12 months since Greater Cleveland Aquarium celebrated Fin Fest 2023.

1: THE STINGRAY SHUFFLE

Recent scientific findings suggest that shuffling can help those who want to avoid being struck by stingrays buried in the sand. Vibrations from these little movements alert rays and give them time to move out of harm’s way. Taking tiny steps also means surfers and ocean lovers are less likely to squish a ray midbody. Stepping down where the rays’ organs are located “makes them strike 85 percent of the time,” say researchers from California State University, Long Beach.

2: LEAN & NOT SO MEAN?

The megalodon has so captured the popular imagination that despite being extinct for millions of years, it is the titular star of a box office franchise starring Jason Statham. Depicted as massively terrifying on the big screen, scientists reevaluating fossil records think the “the meg” might have been somewhat longer, possibly less agile and significantly thinner than previously believed.

3: OH BABY!

A wildlife photographer and filmmaker took footage of a shark off the coast of Carpinteria, California, that might be a newborn great white. IF (and that’s a big IF) it is a baby great white pictured, the imagery could verify that female sharks give birth in the area from Santa Barbara to Baja California. “Anything that gives clues to the lifecycle of their reproductive behaviors of any species is really important in understanding and preventing their decline or extinction,” noted Northeastern University professor Dan Distel.

In related news, the existence of a shark nursery near the “Big Apple” was confirmed. The urban location is believed to be “the primary nursery for North Atlantic great whites, where juveniles learn to feed, navigate and evade predators in relative safety.”

4: PALEONTOLOGY ROCKS

Two new-to-science sharks—Troglocladodus trimblei and Glikmanius careforum—were identified via fossils found in Mammoth Cave National Park, an area that would have been covered by a seaway hundreds of millions of years ago. Meanwhile, an exceptionally well-preserved fossil found in a Mexican quarry is expanding our understanding of the body shape and feeding habits of a distant relative of the modern-day great white shark.

5: WARMING UP TO THE IDEA

Researchers were surprised to only recently discover the globally endangered basking shark might be partially warm-blooded. While the majority of fish are ectothermic and cannot regulate their body temperatures, a few have been found to be regional endotherms, meaning they cannot generate heat in parts of their bodies. “The basking shark is a shining example of how little we know about shark species in general,” zoologist Haley Dolton commented.

6: GHOST HUNTERS

A deep-sea survey discovered a new fish species with an otherworldly appearance. A distant shark and ray relative, the primitive chimaera, or ghost shark, had “giant, glow-in-the-dark eyes, a huge head and feather-like fins.”

7: NOT KISSING COUSINS

When an apparent pregnancy of a lone female ray in North Carolina sparked wild public speculation, the public learned that (due to anatomy and genetics) there was no way that a round stingray could have mated with a neighboring bamboo shark. Although some species of sharks and rays are capable of parthenogenesis, or asexual reproduction, it was eventually reported that this stingray had a rare reproductive disease that led to its loss.

8: GOING THE DISTANCE

Researchers documented a silky shark traveling 17,190 miles—by far the most extensive migration recorded to-date for this overfished and vulnerable species. Tracking showed “Genie” journeying into international waters. The study’s authors believe the long migratory pathway reinforces that international coordination is imperative to help reverse the declining populations of silky sharks.

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

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

These turtles can be a bit forward with their courting rituals—fluttering their claws around the face of potential mates to show interest.

///

Horseshoe Crab

Q&A with United Black Fund of Greater Cleveland

January 11, 2024
 / 
Written by

This year, the Aquarium brings back Difference-Makers Days in partnership with United Black Fund of Greater Cleveland, a week-long event (Monday, January 15 – Sunday, January 21, 2024) highlighting UBF’s work and the achievements of African American innovators.

Guests save $5 on daily admission through the week, and $1 of every ticket sold directly benefits UBF, who will be onsite for MLK Day and January 20-21 to share their mission.

Ahead of Difference-Makers Days, we caught up with UBF Development Coordinator Adrianne Sims for a Q&A discussing the organization’s ongoing impact on Northeast Ohio’s Black community.

United Black Fund at Greater Cleveland Aquarium
Development Coordinator Adrianne Sims (Left)

Question: What is the mission of United Black Fund of Greater Cleveland?
Adrianne Sims:  At the United Black Fund of Greater Cleveland, we believe in actively engaging with our agency partners to help them become sustainable and growth-oriented resources for their communities. We understand the importance of aiding those in need, and that’s why we strive to better prepare the nonprofits that serve them. We’re committed to making a positive impact on the Black community, and we’re here to support our partners every step of the way.

Question: How does UBF impact the Northeast Ohio community?
Adrianne Sims: We are deeply moved by the significant milestones we have achieved in our efforts to support the Black community. Our MORTAR Cleveland Program has successfully launched its first cohort of Black entrepreneurs, and we have been the unwavering financial foundation for several large-scale movements and events that empower the Black community, such as the FutureLAND Conference 2.0. Our commitment to supporting Black-led and owned businesses, particularly those led by Black women, is fueled by our understanding of the challenges they face. We strive to change the narrative that Cleveland is not a favorable place for them and are dedicated to making it a better place. Moreover, we have launched two $25,000 grant initiatives specifically designed to address Black needs. We pledge to continue our efforts to empower and support the Black community and to stand with them through their struggles.

Question: How can people in the community contribute to UBF’s mission? 
Adrianne Sims: We understand the importance of giving back to the community, and that’s why we at the United Black Fund of Greater Cleveland are grateful for the incredible generosity of our donors and foundations. It’s their kindness that enables us to provide vital resources and support to various organizations, helping us further our mission of empowering and uplifting the community. We welcome you to join us in this inspiring movement toward positive change in the Black community by visiting our website or connecting with me (Adrianne Sims, Development Coordinator) to learn more about how you can contribute to this cause. Together, we can make a difference in the lives of those who need it the most.

Question: What are some of the biggest challenges facing the Black community in Northeast Ohio today?
Adrianne Sims: It’s crucial to acknowledge the tough realities that the Black community in Northeast Ohio are facing. It’s heartbreaking to know that Cleveland has been designated as the worst city in America for Black women, but we understand that this is just a fraction of an even more significant issue. The environment in which our community lives has a profound impact on our access to quality healthcare, economic stability, affordable housing and quality education. We understand that immediate action must be taken to ensure that the Black community in Northeast Ohio receives the resources and support it deserves to thrive and have the quality of life that every human deserves. We feel the need to connect the dots of environmental justice and uplift Dr. Martin Luther King Jr.’s legacy of justice for all by linking it to the environment, climate, housing stability, healthcare and education because we firmly believe that every individual deserves to live in a safe and prosperous environment.

Question: What have been some of the benefits of the UBF and Greater Cleveland Aquarium partnership?
Adrianne Sims: There have been many benefits: This partnership has expanded the information, (our mission, programs, Grantees and Donor Advised Funds, etc.), of United Black Fund to Greater Cleveland Aquarium’s audience. Attendees have actively engaged with UBF about the new information regarding Greater Cleveland and the African American community. This collaboration has raised awareness of pioneering African American marine scientists and environmental researchers, along with highlighting Dr. Martin Luther King Jr. and his work not only in our nation, but in the Greater Cleveland area too!
