Ocean Lemon Drop

Aegina citrea are less common at 300 meters (980 feet) than the many other species of Aegina, but their unusual bright yellow coloring and size (nearly twice that of other Aegina species) are striking. These animals are stealth predators that push their tentacles ahead of their body or bell as they swim through the water. This allows their stinging tentacles to catch prey before their prey even know they are near. See more images of mid-water creatures in our slideshow.
