Branch of Pink Soft Coral Close - Red Sea, 2008
The "stem" of this type of soft coral takes in water when there is a current in order to create more surface area to absorb nutrients. For further description see Orange Soft Coral Stem, Light Pink Soft Coral with Crinoids and Red and White Soft Coral. For an example of the soft coral when not puffed up see Crinoid and Soft Coral Bouquet.
