Description

 Leucosolenia botryoides is a very delicate, soft, white, tubular sponge that grows to up 2 cm wide and 1 cm thick. The base consists of a network of encrusting, root-like tubes from which slender, vertical tubes, grow up to 2 cm in height. Each tube bears a large oscula (exhalant pore) at its terminal end that opens to an internal central cavity. The body wall contains 3-pointed and 4-pointed calcareous spicules and is covered on the outer surface by minute hairs.Leucosolenia botryoides is an annual species that reproduces in the summer and autumn. It is similar to Leucosolenia complicata but that has branches extending laterally from the vertical tubes which Leucosolenia botryoides lacks.
