Pacific sea nettle, Chrysaora fuscescens. Scyphozoa / jellies / jellyfish. Monterey Bay Aquarium, California, USA.
Pacific sea nettle, or Ortiga de mar (Chrysaora fuscescens), Monterey Bay Aquarium, California, USA. Although commonly named "jellyfish," jellies are plankton, not fish. Jellies (class Scyphozoa) lack the backbone (vertebral column) found in fish. Jellyfish have roamed the seas for at least 500 million years, making them the oldest multi-organ animal. A sea nettle hunts by trailing long tentacles covered with stinging cells to paralyze tiny plankton and other prey. Stung prey is moved to the frilly mouth-arms and on to the jelly's mouth. The Monterey Bay Aquarium (MBA) was founded in 1984 on the site of a former sardine cannery on Cannery Row along the Pacific Ocean shoreline. Fresh ocean water is circulated continuously from Monterey Bay, filtered for visibility during the day and unfiltered at night to bring in food. Monterey was the capital of Alta California from 1777 to 1846 under both Spain and Mexico. In 1846 the US flag was raised over the Customs House, and California was claimed for the United States.Add to Cart Add to Lightbox Download
