This institution is popular for its botanical galleries, characterized around 3000 pieces of handblown, and complicatedly crafted glass flowers and plants. There is a smaller, integral display of Sea Creatures in Glass by the same artists. Close by, the zoological galleries house an enormous number of stuffed animals and reassembled skeletons, as well as an impressive fossil assortment. Other cool exhibits highlight environmental change, sparkling gemstones and arthropods (yes, cockroaches). The cost of admission includes section into the Peabody Museum of Archaeology and Ethnology, which is in the same structure. The Museum of Comparative Zoology (MCZ) is situated on Harvard University's grounds and is a piece of the Harvard Museum of Natural History, which has two different museums as well.
