Upon donating an acorn barnacle 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. It is found on the large rock. The exhibit has this to say about the acorn barnacle:

"They attach to hard places, and though they look like bivalves, they are related to shrimp and crab. Some species are even edible and have a very crab-like taste to them, making them a fine delicacy. Young acorn barnacles come from eggs, do not have shells, and float around the ocean like shrimp. They gradually develop their shells as they grow into the image we usually see."
