Characteristics edit
Members of the genus Dolioletta are transparent, gelatinous barrel-shaped animals, usually less than one centimetre long. They move in jerks by contracting the circular bands of muscle in their body wall sharply.[2]
Biology edit
They have the complex life cycle typical of the doliolids, with alternating sexual and asexual phases. They use a net of mucus strands to efficiently trap phytoplankton floating past. They both grow fast and multiply rapidly and a single animal is capable of forming thousands of new individuals in a few days. They sometimes form dense swarms with up to 500 individuals per square metre.[2]
