Giant Squid

A replica of a giant squid, Architeuthis dux, looms from the ceiling to greet guests as they enter the Museum. Giant squids (Architeuthis sp.) are the largest invertebrates (animals without backbones) alive on Earth today. These enormous animals reach lengths of 18 m. (59 ft) from the tips of their tails to the ends of their tentacles. For comparison, this model is a more typical size of 9.7 m (32 ft) long.  Squids belong to a class of mollusks called cephalopods. Although all cephalopods live in the ocean, they are closely related to snails and slugs.  Where [...]


Hall of Mollusks

What is a mollusk? In general, mollusks are soft bodied animals living in many different environments: from the depths of the oceans to the heat of the desert, and from small backyard ponds to the tops of mountains. They are one of the most diverse groups of organisms on the planet. The Phylum Mollusca is estimated to include 100,000 species. The study of mollusks is called malacology (mal-uh-col-oh-gee) which means “the study of animals with soft bodies.” The seven living classes of mollusks are Aplacophora, Bivalva, Cephalopoda, Gastropoda, Monoplacophora, Polyplacophora and Scaphopoda. All seven classes are [...]


Hall of Birds

Birds occur in almost every part of the world. As you explore this gallery, look at the amazing diversity of birds that live and thrive in the Delaware woods, in tropical rainforests, and even on rocky cliffs. In addition to the birds in this gallery, the Museum houses 113,000 bird specimens and nests in its behind-the-scenes Collections and Research Division. Take a behind the scenes tour, including the space behind the exhibit area, with Exhibits Director Helen Bilinski. The Philippine Rainforest Tropical rainforests are warm and wet all year. [...]


Hall of Mammals

Hello! This page is currently under construction. If you see this message, the people behind the page are updating it. Stay tuned! African Watering Hole It’s not really Kenya, but it is the next best thing. Imagine that you are transported to a watering hole near Mount Kenya National Park in Kenya, Africa. All of the animals you see here come to watering holes during the dry season. They would not all share the watering hole at the same time. Instead, some animals would come during the day, others at night, [...]


Dinosaur Gallery

Standing in the midst of the Hall of Birds are two mounted Chinese dinosaur skeletons from the Sichuan Basin: A two-footed meat eater named Yangchuanosaurus and a four-footed plant eater named Tuojiangosaurus. Both lived in the Late Jurassic period 150 million years ago. Both were found in the Shaximiao rock formation of purplish-red mudstones in present day Sichuan Province. Yangchuanosaurus magnus means the large lizard of Yangchuan, China, where it was discovered by farmers in 1985. It was fossilized in the mudstone rock lying on its side nearly intact, which is very unusual. Yangchuanosaurus was an active carnivore, weighing [...]
