Sponge - A beautiful Haliclona sp. specimen from Chek Jawa, Singapore. Haliclona permollis showing multiple chimneys of a single individual sponge. Seawater is pumped continuously through a sponge by the beating activity of flagella that line the internal cavities. Water is drawn into the sponge through many small intake openings located on the outside surface and is released from exhalent openings on chimneys and vented away.
These pieces were created by Karen Margolis and they interest me because they remind me of something that has come out of the ocean suck as a sea sponge or coral. The holes in paper and the pale colours give that effect.
