Unveiling the 24-Eyed Mystery: A New Jellyfish Species Discovered in Hong Kong (2026)

Prepare to be amazed by nature's wonders! Scientists have stumbled upon a mind-boggling creature with an extraordinary feature—a staggering 24 eyes! This tiny jellyfish, Tripedalia maipoensis, was found in a shrimp pond, but its discovery is making a huge splash in the scientific community.

The Enigmatic Box Jellyfish

Part of the box jellyfish family, Tripedalia maipoensis is a tiny marvel, measuring just half an inch long. Its bell, almost transparent and six-tenths of an inch wide, forms a nearly perfect cube. But the real surprise lies in its unique appendages. Each corner of the bell sports three flattened structures called pedalia, which aid in swimming. And attached to these pedalia are long tentacles, reaching up to four inches.

A Visionary Wonder

The true marvel of this jellyfish is its eyes. With 24 eyes arranged in four clusters, or rhopalia, it's a sight to behold. Two eyes in each cluster are large and image-forming, while the others are simpler, detecting light and dark. Professor Qiu Jianwen from HKBU believes these eyes are crucial for navigation and hunting, showcasing the creature's remarkable adaptability.

But here's where it gets fascinating... Despite lacking a brain, Tripedalia jellyfish display complex behaviors. They can alter their swimming patterns after encountering obstacles, a skill known as associative learning. This ability to learn and adapt is not unique to them; certain octopus species also exhibit similar cognitive prowess.

An Urban Biodiversity Hotspot

The Mai Po Nature Reserve, nestled near an urban landscape, has unveiled a hidden gem. Tripedalia maipoensis was discovered here, highlighting the potential for more undiscovered species in human-modified habitats. Professor Qiu emphasizes the significance of this find, suggesting that less disturbed wetlands could be home to even more mysterious creatures.

And this is the part most people miss—the idea that familiar environments may still hold secrets waiting to be uncovered. It's a thrilling reminder that nature always has something new to reveal, even in our own backyards.
