- "Blech! I caught a giant isopod! That's a horror if ever one existed!" —New Leaf
The giant isopod is a rare, benthic aquatic life form found at the bottom of the sea in New Leaf. It is indicated by a circular shadow, and diving is the only way of capturing it. It is exclusive to the Island. Since the season never changes at the Island, it can be caught all year long.

"Giant isopods are related to pill bugs, and they can grow up to 20 inches long. They are scary looking but still come across as humorous for some odd reason. Despite their roly-poly builds, they are surprisingly fast swimmers, making them rather agile. They have big appetites, gaining the title "sea cleaners" mostly because they eat dead fish on the seafloor."

Giant isopods can be any number of twenty separate species of large isopod but often refer to the largest isopod, Bathynomus giganteus. They live mostly in deep, cold regions of the Atlantic, Pacific and Indian Oceans. Their discovery by French Zoologist Alphonse Milne-Edwards played an important role in proving that the deeper regions of the sea were not lifeless as was assumed at the time in 1879. The reason for its size is attributed to 'Deep Sea Gigantism' a phenomenon where living things tend to grow larger the further from the surface of the ocean they get. Some scientists believe it is so to deal with immense pressures of water above them, but the reason is still a mystery.
