  • Relicanthus daphneae, a deep-sea anemone first described in 2006, with tentacles that can stretch over six feet long.

    The golden orb turned out to be a cuticle, a thin, multilayered coating that some anemones secrete from their outer tissue. Made primarily of chitin, the same tough material found in beetle shells and fungal cell walls, it forms flexible sheet-like structures that can detach and stay on the seafloor while the animal moves on. The anemone, in other words, just got up and left its own skin behind.
