Description
Yellow zooanthids on a glass sponge. Note that, though highly conspicuous underfull light, they blend in with the sponge at blue wavelengths. These animals have been quite interesting because they also have bright green fluorescence andvery strong green bioluminescence. They also stung our hands when we touchedthem, suggesting that some of these signals may be warnings of toxicity. (Image credit: Operation Deep Scope 2005 | Sonke Johnsen)
