Purple Vase Sponge are visible from a ways off as you swim along the reef and I like to think of them as a present.... pretty on the outside with a treat on the inside.  

They come in colors pink, purple or even fluorescent blue with a rough exterior of convoluted ridges and valleys.

Once you are done admiring their outside beauty it's always worth a peak inside.... as there is often an addition treat nestled in there. In this case it's a couple of Hermit Crab.
