Within the depths of the Academy of Sciences, there’s a tunnel called the Flooded Forest. People can sit there for hours and see all kinds of fish drifting overhead. It’s inspiring to see; no matter where you’re from or what language you speak, nature is fascinating for everyone. Larger version is viewable here.
At the Academy of Sciences, there’s a cool exhibit that features a dozen or so Moon Jellies in a cylinder. There’s a light shining into the water that changes color every few seconds…and so do the moon jellies. Here’s a close shot of some in red. Larger version can be viewed here.
Here’s a little something from the aquarium at California Academy of Sciences. The tank is pretty dark, save for the shaft of light going down the center. I caught this jellyfish swimming close through the light at just the right moment…Larger version viewable here.
This week’s challenge calls for some close-ups, and I immediately thought of this shot. Meet phyllorhiza punctata, more easily pronounced as a white-spotted jellyfish. According to the display, “These jellies can grow up to 60 cm (24 in) in diameter. The stinging cells in their tentacles capture food and provide protection. Each large jelly can collect food from 50 m³ (65 cu yd) of water a day. Diet: small zooplankton. Distribution: coastal areas and estuaries in the Southwestern Pacific, invasive in Hawaii and the Gulf of Mexico.” I photographed this little one, however, at the aquarium at the California Academy of Sciences in San Francisco.
This week’s challenge is all about forces of nature, so I thought I’d post something about light and its effects of animals. Here’s another Exploratorium exhibit. Basically, zooplankton can distinguish different colors of light. In the ocean, it helps them swim toward the surface, where their food is located. Blue and green lights shine deeper in the water than the other colors, hence why the plankton are attracted to these ones; they think the sun is shining through the water, and that they’re entering the photic zone for a meal.
