This jellyfish is capable of producing flashes of blue light by a quick release of calcium (Ca 2+), which interacts with the photoprotein aequorin. The blue light produced is in turn transduced to green by the now famous green fluorescent protein (GFP). This transduction of energy is called Förster resonance energy transfer (FRET). Both ...
Blue gelatinous creatures known as by-the-wind sailors often wash up on California beaches by the thousands in the springtime when the ocean warms. Blue jellyfish-like critters arrive in Bay Area ...
Often the tank's background is blue and the animals are illuminated by side light, increasing the contrast between the animal and the background. In natural conditions, many jellies are so transparent that they are nearly invisible. [138] Jellyfish are not adapted to closed spaces. They depend on currents to transport them from place to place.
We looked down and discovered we were rapidly descending onto a huge school of pale blue jellyfish. Shrieking, we grasped our barf-covered legs, praying we didn't crash into a jellyfish. Luckily ...
It is transparent and pale blue, with four primary noncontractile tentacles set high above the margin of the dome-shaped bell. Lower down near the undulating margin are four short secondary tentacles, each with a statocyst on either side. The central circular mouth on the oral surface leads to a gastric chamber out of which lead 12 gastric ...
