Mesmerizing jellyfish take center stage at US museum dedicated to the creatures

POMPANO BEACH, Fla. -- The floating tentacled predators pulse and swirl in hypnotic patterns in the dark museum space, lit primarily by images projected on the walls and the glowing light from the saltwater tanks.

The private Jellyfish Museum in Pompano Beach, Florida, just north of Fort Lauderdale, is believed to be the first museum in the United States dedicated solely to the translucent invertebrates, and one of the few such spaces in the world, according to the city and the museum’s founders.

It was created by Alex and Yana Yanovsky, who previously developed successful aquariums in Ukraine, including their first jellyfish museum in Kyiv. The couple left those facilities behind when they fled Ukraine following the 2022 Russian invasion, operations manager Jessica Eisenbarth said.

The museum, which opened this past spring, is the couple's first aquatic attraction since immigrating to the U.S., but they'd like to expand.

“When they left Ukraine, they moved to Florida, and then they immediately wanted to share their passion here,” Eisenbarth said.

Jellyfish have survived for over 500 million years, making them older than dinosaurs and even trees. Their ancient origins are part of their allure, along with their hypnotic, pulsing movements. They have no heart or brain, and are made up primarily of water, giving them a translucent look.

Yana Yanovsky came up with the idea for the jellyfish museum after noticing how popular the jellyfish were at their other aquariums.

“Jellyfish are some of the most resilient creatures on Earth. While they lack a brain, they maintain a simple nerve net that allows them to respond to their environment,” Yana said in a statement provided by the city. “Their movement is mesmerizing, almost meditative, and they play an important role in marine ecosystems.”

Monty Graham, director of the Smithsonian Environmental Research Center, said he’s not surprised someone made an aquarium dedicated specifically to jellyfish. He credits the Monterey Bay Aquarium in California with kicking off the popularity of jellyfish exhibits at aquariums all over the world. Monterey Bay Aquarium began displaying jellyfish in temporary exhibits in 1985 and opened a permanent gallery in 1996.

“Jellyfish are cool, they’re things that people don’t get to see up close unless they’re scuba diving,” Graham said. “So here was this opportunity, in a controlled environment, very beautiful settings. It clicked all the buttons and checked all the boxes, and it was a very good, positive thing.”

The nearly 10,000-square-foot (900 square meters) Jellyfish Museum houses roughly 20 unique species of jellyfish found in Florida waters and other parts of the world. Different species can be rotated through the museum's 21 tanks.
