There are so many videos on TikTok these days that you can’t help but see dance crazes and cute animals. But below the surface, or underwater, there are some unique, critically endangered crustaceans that have joined the trend by accident. Lisa Desjardins reports.
The Magical Mystery Dance Uncovering Why Shrimp Engage in Their Captivating Rhythmic Displays
In aquatic environments around the world, shrimp of many species are known for their graceful, hypnotic dancing displays The sight of shrimp bobbing and weaving in unison never fails to delight observers But what drives shrimp to dance in the first place? Their rhythmic movements hold an air of mystery, spurring curiosity into the reasons behind this quirky crustacean behavior. Let’s explore some leading theories behind shrimp dance moves to unravel the question – why do shrimp dance?
Shrimp Dance Magnificence
The shrimp dance is a spectacle of coordinated motion containing complexity and elegance. Multiple shrimp moving in sync create a mesmerizing effect, swaying their legs and antennae while pivoting their bodies. Some components of the dance involve:
- Backward and forward hopping
- Pivoting and circling
- Leg and antenna wiggling
- Touching antennae
- Tail fluttering
- Color changes
This choreography transpires across various shrimp species like the cardinal shrimp, harlequin shrimp, red cherry shrimp and more. While captivating to watch, the shrimp’s intricate dance likely serves meaningful functions for their survival.
Communication Through Dance
One prominent theory suggests shrimp dances are a means of communication. Shrimp lack vocal cords, so conveying information visually is necessary. Dance moves may communicate vital messages, including:
- Gathering colony members
- Indicating food sources
- Courting and mating signals
- Territorial displays
- Expressing alarm at threats
Shrimp can observe the dances of others and rapidly mimic the movements, allowing information to spread. So dance steps evolving into a common “language” enables shrimp to coordinate essential activities.
The Mating Dance
In particular, shrimp dance moves play a key role in finding a mate. Male shrimp initiate courtship dances to attract nearby females. A sultry swaying of the body, fluttering of antennae and waving of legs signals readiness to breed. If interested, the female will join the male’s dance, mirroring his movements. The tandem dancing culminates in the two shrimp coupling to reproduce.
Researchers believe more vigorous, longer dances increase mating success. So the livelier the dance, the better chances of the male shrimp sealing the reproductive deal.
Marking Territory Through Dance
Dances also allow shrimp to define personal space and mark territory. As organisms lacking protective outer shells, shrimp need to establish clear borders to avoid confrontations. Their dances communicate “this area is occupied.”
Each shrimp has a preferred zone that it will defend. When an intruder encroaches, the resident shrimp initiates an aggressive dance to drive the trespasser away. Neighboring shrimp respect these marked boundaries, helping maintain harmony.
Warning Signal Through Dance
Shrimp dances also act as alarms against immediate threats in the environment. When sensing danger, like an approaching predator, shrimp will initiate a frenzied, erratic dance. Nearby shrimp quickly mimic these frantic movements, signaling everyone to seek safety.
The flashing colors and jerky motions of alarmed shrimp also help confuse predators. So the communal dance both spreads a warning and hides individuals in chaotic motion.
Why Do Pet Shrimp Dance?
The natural dancing behavior of shrimp continues even in captivity as pets. Tank-raised shrimp like the Red Cherry Shrimp display frequent energetic dances. Why do pet shrimp still feel the urge to dance even in safe confinement?
Some possible explanations:
- Instinctive response ingrained over generations
- Excitement triggered at feeding time
- Reaction to tank maintenance like water changes
- Attempt to attract a mate without opposite gender present
- Territorial response to seeing their reflection
So even in absence of predators and mates, pet shrimp retain their hard-wired need to bust a move!
The Joy of Dance Discovery on Social Media
One unlikely place shrimp dance has found fame is on social media. A TikTok account called ShrimplyBeautiful showcases ornamental shrimp busting spontaneous moves to music. Set to trendy beats, the shrimp’s natural boogie captivates viewers.
While not the account owner’s intention, these viral “shrimp raves” have brought awareness to endangered species like the nearly extinct Lake Matano shrimp. Their shrinking habitat in Indonesia has fueled efforts to protect the remaining populations. So social media shares of dancing shrimp promote conservation of threatened species.
Scientific Curiosity Over Shrimp Grooves
The reasons behind aquatic arthropod dance moves remains an area of ongoing research. Scientists continue working to decode the nuances of shrimp communication and social structure reflected through their dances.
Unlocking these secrets may help support shrimp preservation and aquaculture. For now, science still contains many unsolved mysteries around the rituals of dancing shrimp. But we can revel in the simple joy of witnessing their elegant, eternal dances, generation after generation.

- Lisa Desjardins: You can’t miss dance crazes and cute animals on the video-sharing app TikTok right now. But if you look below the surface, you’ll see that some critically endangered crustaceans have accidentally joined the trend. It’s called a Shrimp Rave, and it has electronic music, rotating grooving shrimp, and glowing shrimp. The shrimp lead’s beautiful TikTok account has videos of these one-of-a-kind extravaganzas. It is run by Timothy Utterback, a conservationist and student at California State Fullerton. Cal State Fullerton student Timothy Utterback: “I would put educational videos or kind of lo-fi piano relaxing videos of the shrimp.” I would put captions about how endangered their species is and other things, but they never really seem to stand out. Once I started putting the entertaining music on. A lot of people were drawn to it.
- Lisa Desjardins: The Cardinal Sulawesi shrimp are the stars of the show. They are a small species of critically endangered animals that want to come from an old lake in Indonesia, but no one has seen them there since 2013. Many people said that the population loss was caused by nearby nickel mining and other things. They might now be completely extinct in the wild. Utterback says that the main reason he breeds them is to help them have more fun than just his live broadcasted room raves.
- If there are a lot of captives, Timothy Utterback said, we might have to bring them back, whether it’s in five, ten, or twenty years. Once they were happy, they had way too many babies. I went from having 30 to having over 1000.
- Lisa Desjardins: They became famous on TikTok not by dancing but by eating a lot.
- Tim Utterback: The shrimp started eating their arms, which means they’re growing really fast. They also love being in small groups, which makes it look like they’re synchronized dancers.
- Lisa Desjardins: These shrimp raves can just happen anywhere. It is hard to make Lake Matano look like their home environment, which is on the other side of the world. The lake is thought to be between 1 and 4 million years old. Further, it is one of the world’s deepest lakes and a treasure trove of minerals and plants.
- Tim Utterback: When I’m taking care of the aquariums, I feel like I look like a crazy scientist. I always have five or six test tubes in my room where I test the water for many things to make sure the shrimp have a good place to live.
- Lisa Desjardins: Striking the chemical balance is a tricky task. That being said, Utterback says he wants to make videos that teach people how to do it themselves. That way, the shrimp population can grow, and people will be happy in the process.
- The shrimp rave makes a lot of people happy. Some people tell me they’ve had a really bad day because they got fired, their boyfriend broke up with them, or something else. But when they see the rave, it makes them feel a lot better. Shrimply Beautiful. Shrimp rave.
- After millions of views, Utterback and Shrimply Beautiful are bringing a lot of attention to one of the world’s smallest animals that is in danger of going extinct.
