You might not know this, but Amazon has a pretty cool feature called the stream, which it fills with “interesting finds” that people can check out. If someone likes a product featured in the stream, he or she can favorite it by clicking the little heart. Most products in the stream get a couple hundred favorites, and really popular ones might get a few thousand favorites. The EcoSphere Closed Aquatic Ecosystem Pod has more than 62,000 combined favorites across all the different shapes and sizes, as you can see in the screenshot below.

These little pods are actually pretty darn cool. Each one is made of hand blown glass, and they’re filled water, a branch, some decorative rocks… and actual living marine shrimp. The shrimp inside these crazy little ecospheres live for between two and three years, and they’re entirely maintenance free. It’s no wonder so many people out there love them.

Some highlights from the product page:

The EcoSphere
The EcoSphere is a completely closed, balanced, glass ecosystem. Inside each EcoSphere are shrimp, algae, and microorganisms in salt water. Because the EcoSphere contains everything it needs to thrive, you never have to feed the life within or change the water. All that is needed is a comfortable room temperature (between 65 and 80 F) and a source of light.

EcoSphere Handbook
Each EcoSphere comes with a handbook detailing how to take care of the EcoSphere. Also included is an outer cleaning magnet that, when matched up with the magnet inside the EcoSphere, can be used to clean the inside of the EcoSphere.

Shrimp in the EcoSphere
The EcoSphere contains active marine shrimp that feed on the algae inside the EcoSphere. Each model of EcoSphere contains a certain number of shrimp based on the interior volume.
