This solitary and huge soft coral was situated near the ledge of a hard coral wall. The base was about 6 inches in diameter. The 'stem' of this type of soft coral takes in water when there is enough current to feed, thus making the organism more upright providing more surface area to absorb nutrients. In this image the coral is not completely saturated so it's leaning over a bit. For an example of this type of soft coral when it is not 'puffed up' see Crinoid and Soft Coral Bouquet.
