The spiny lobster gets its name from the large long spines protruding from the front of its shell. They vary in color from pale almost white, to deep orange, to dark red and brown. These lobsters occasionally participate in mass migrations where a lead lobster will be followed by thousands of others marching in a single file line.
The barnacle is a very common site around the ocean. They are frequently seen in clusters attached to boats, docks, and even whales. Barnacles are filter feeders. They feed on plankton and other floating debris and spend their entire lives permanently attached to one spot.
