The second coin in the series represents the "Yellow Tube Sponge", scientific name Aplysina Fistularis; it's a type of coral that lives abundant in the Caribbean, from Florida to Venezuela. Soft-walled tubes, usually in clusters joined at the base, in natural light, especially in deeper water, they appear to be yellow-green.

Aplysina Fistularis - CORAL REEF
Yellow tube sponges get their name from their hollow, chimney-like body form. They pump huge quantities of water through their bodies, filtering out the tiny particles on which they feed. At shallow depths yellow tube sponges have a shape which resembles a cactus. In deeper waters, the sponges develop long, straight tubes. Inhabit reefs in open water areas and are often growing on vertical walls.
Their vivid yellow colour is probably due to special fluorescent pigments in the sponge tissue; in natural light, especially in deeper water, they appear to be yellow-green.
