Chrysaora - The Pacific sea nettle
One of the most popular and most photographed exhibits at the Monterey Bay Aquarium is the beautiful mesmerizing ballet of sea nettles. The Pacific sea nettle, Chrysaora fuscescens, lives in coastal waters from Alaska to California, to Japan, Kamchatka, the Aleutian Islands, and the Bering Sea. With their long, trailing tentacles these jellies are large: their bells are about 17.7 inches (45 cm) in diameter, mouth-arms from 12 to 15 feet (3.6 to 4.6 m) long. The frilly mouth-arms and tentacles are covered with stinging cells, called nematocysts.

Hope For Coral Reefs
Worldwide coral reefs are suffering from the impacts of climate change. Around the world researchers are pioneering ways to protect and restore coral reefs that have already bleached. Between these efforts and the amazing capacity for corals to adapt to healthier environments, there seems to be some hope. Corals can be attached to reefs piece by piece with cement, zip ties, and nails. (Photo: Reef Resilience Network)
