Beachcombing

Sea fan, several sizes of sea urchins, a tiny starfish, and coral.

The Babies.  Check out the pic above to get an idea of the scale.  The starfish is the biggest in this pic, but is actually smaller than a quarter.  While many times, searching for the biggest shell is common, sometimes it's fun to find the teeniest shells too.  Those white sea urchins are smaller than a pea!

Three different shapes of sea sponges and two types of corals

Sea glass.  My favorite color is the sea foam green.  These colors: brown, dark green, sea foam green, and white are the most common colors.  Rare colors include cobalt blue, red, purple, yellow, and black.  

Various shells.  It is quite easy to come home with a gallon-sized bag of them after only one beach trip.

Another sea fan and a piece of driftwood.  The sea fans and sea sponges were quite plentiful after Hurricane Sandy.  Otherwise, they are quite easy to find while diving, but don't wash up on shore as readily as shells.
