Pearl Oyster (deep sea creature)
From Nookipedia, the Animal Crossing wiki
Pearl Oysters (アコヤガイ, Akoyagai) are a type of deep sea creature found in Animal Crossing: New Leaf. In all games, Pearl Oysters also are found as shells. Despite their name, they are not related to oysters but moreso to clams and other bivalves.
Donating to the Museum
In New Leaf
Upon donating the Pearl Oyster to the Museum, it can be found in the large pool in the first room of the ocean exhibit, along with many other species of deep sea creatures. The exhibit has this to say about the Pearl Oyster:
"Pearls are formed when mostly calcium carbonate and protein envelop foreign substances. Pearl oysters have numerous threadlike feet sticking out from their shell opening. These allow them to latch onto surrounding rocks and are actually surprisingly strong. Their adductor muscles are edible and are considered a delicious ingredient in some foods."
Despite being a Fishing Tournament, Chip will still accept deep-sea creatures, however, they will not be scored. Chip will say this when given a Pearl Oyster:
