I went to an aquarium and I petted a shark called a dogfish. It felt rough, but cool. There was a anther touch tank with scallops, crabs, horse shoe crabs, sea stars, hermit crabs and sea cucumbers. In another tank was a giant lobster. It could probably feed about 20 people!
You should go there. http://www.maine.gov/dmr/rm/aquarium/index.html
