Description & habitat
This species has a maximum size of 70 mm. The background color is deep black. The margin of the parapods and body are marked with a fin electric blue line. The two rather long "tails" at the end of the animal are characteristic of the genus Chelidonura, the left one is always longer. They have also well-developed sensory cilia on the anterior edge of the head which are used to find the preys.
This species lives on reef areas in shallow water lagoons with sandy or muddy bottom until 30 m depth.
This cephalaspidean is widespread in the tropical waters of the Indo-west Pacific region.
