Aquarium Installs Sushi Roll Cylinders For Eels To Slide Into Joseph Muna Updated in Nov 2021 A Japanese aquarium installed cute sushi roll cylinders for eels to slide into and it is now one of its most popular attractions. Setsubun is a day in Japan that marks the beginning of spring. Many people eat Ehomaki, a particular long type of sushi roll filled with various ingredients, for good luck. Saltwater Conger eels (Anago) love their safe, narrow spaces. You can spot them hiding in caves or burying themselves in soft sediment or sand. They can grow to about 40cm to 90cm and are usually parts of the ingredient in Ehomaki. And last year, Sendai Uminomori Aquarium played on that concept with the clever idea of installing Ehomaki-shaped cylinders for their eels to burrow through and slide into. According to the aquarium's website, they have relaunched the exhibit due to popular demand. Unfortunately, the exhibit closes on February 2, so you better act fast if you want to visit the aquarium. Here are some of the images from the exhibit. The attraction has become so popular that Sendai Uminomori Aquarium has launched a new giant Anago Ehomaki plushie. This must be one of the most adorable stuffed animals we can think of! You can get it from the aquarium's gift shop.
