Giant Barrel Sponge Xestospongia testudinaria occurs widely distributed in the tropical Indo-Pacific in a depth range from 2-50m. Specimen in the intertidal zones remain small with 10-20cm diameter, below they can grow to impressing sizes, measuring up to 2.4 meters in height and width.  \nThe sponge is covered with several Sea Cucumbers Synaptula lamperti, found in the Western Pacific including the coasts of Indonesia, Papua New Guinea, Micronesia and the Philippines. The species is very common on coral reefs, both on the exposed and the inner slopes. It is a detrivore that specifically feeds on or around living sponges. \nConsidering the sea cucumbers maximum size of 20cm, the barrel sponge might extend more than 1m from the reef slope.  \nBanda Island, Indonesia, 4°30'45.41 S 129°56'7.75 E at 13m depth

These sponges are NOT photoshopped, that's the real color! The whole area is full of Bubble Tip Anemones Entacmaea quadricolor. A lot of Acropora sp. hard corals. Some Tropical Striped Triplefin Helcogramma striatum (4 cm = 1.6 inches) are there. A dive in Indonesia without them is quite rare! Many Stinging Hydrozoan Aglaophenia cupressina, they are useful to indicate good buoyancy to divers, as bad one is painful! South West side of Pura Island, Pantar Strait, Alor, Indonesia, 8°19'8\
