blob sponge Mycale sp.* Family Mycalidae updated Oct 2019 Where seen? This bright orange sponge is sometimes seen on coral rubble on some of our shores. Features: 8-10cm in diameter. The sponge starts inside a crevice but can eventually grow into a dome-shaped or oval shape with a smooth surface, sometimes with small holes (0.5cm). In some, the holes are occupied by tiny brittle stars, with only their short arms sticking out. Some may also be inhabited by animals with a feathery fan, or have unidentified tiny beige bits on the outside. Colour a vivid orange-red. Bright orange sponges which are encrusting may come from a variety of species and families including Tedania sp. and Hymerhabdia sp. They are difficult to tell apart in the field. |
