Sponges are suspension feeders, and in Antarctica are commonly preyed on by starfish, however the spicules on Cinachyra antarctica probably act as a defence against predators, preventing them from reaching the sponge body.
Some estimates have calculated that Cinachyra antarctica may reach 1,550 years in age. However there is no way to directly determine the age of a sponge, so this estimate was derived using oxygen consumption and metabolic rate as an approximate measure.
