Aplysina cauliformis, also known as the Row Pore Rope Sponge, is a very non-distinctive sponge found along the ocean floor, deep sloping reefs, and lagoons. They are found primarily off the coast of Florida, and stretch all the way to Curacao, which is an island in the Caribbean Sea. These sponges are long, rope-like and have branching “arms” which can reach lengths up to 60 cm. The ropy branches can grow quite long -- to a maximum of 180 to 240 cm (about six to eight feet ). The oscules of the sponge have rather thin lips, which are a light reddish color, usally. The surface of the sponge is very stiff and very non-compressible. The colors of this sponge can range from red to purple to lavender.
