"Dead man’s fingers(Xylaria polymorpha)is a saprobic fungus. It is a common inhabitant of forest and woodland areas, usually growing from the bases of rotting or injured tree stumps and decaying wood. As its name suggests, it has a very variable but often club-shaped fruiting body resembling burned wood. Often this fungus is found with a multitude of separate “digits” but at times the individual parts will be fused together."
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.
