Invertebrates

May 7, 1987 - Permanent

Museum: National Zoo

Location: Olmsted Walk, Reptile House, Lower Level

Invertebrates -- creatures without backbones -- are the most abundant creatures on earth, crawling, flying, floating, or swimming in virtually all of Earth's habitats. About 99% of all known living species are invertebrates. This exhibition is home to such invertebrate species as sea stars; spiny lobsters; sea anemones; corals; insects; spiders, including tarantulas; mollusks; and giant Pacific octopuses named Octavius and Pandora.

• Blue Crab and the Chesapeake Bay
This section higlights the biology and ecology  of the blue crab (Callinectes sapidus), focusing on its life cycles and its environment in the Chesapeake Bay. Topics discussed include how blue crabs take advantage of a diversity of habitats in the Bay during different stages of their life cycles, how crab populations reflect the overall health of the Bay -- crab populations decrease as pollution levels increase; and how our everyday actions affect the blue crab and the entire Chesapeake Bay ecosystem.
