Here's a novel treat: a senbei rice cracker made of giant isopods, creepy crawlies from the ocean deeps. The snacks are now on sale at a range of outlets in Japan and are quickly gaining popularity.

Giant isopods resemble pill bugs, their terrestrial counterparts. They are crustaceans, so are distant relatives of crabs. Around 10 cm long, they live at a depth of 600 meters.

They have become popular on the Internet and in aquariums for what some people consider to be their creepy-cute appearance.
