"First report of the exotic blue land planarian, Caenoplana coerulea (Platyhelminthes, Geoplanidae), on Menorca (Balearic Islands, Spain)".
^ Breugelmans, Karin Quintana Cardona, Josep Artois, Tom Jordaens, Kurt Backeljau, Thierry (2012). It is known to feed on several arthropod groups, such as woodlice, millipedes and earwigs, as well as on land snails. This planarian is a predator of a variety of invertebrates on the forest floor. It is often seen after periods of heavy rain. It is found in moist forest areas, and during drier periods it shelters under rocks, rotting logs and in leaf litter. This species has however been accidentally introduced to the Balearic Islands, Argentina, Canary Islands, France, U.K (Portsmouth) and the USA (including California, Florida, Georgia, Texas, South Carolina and Iowa). This flatworm's native range is eastern Australia and New Zealand.
The head on some individuals has a pinkish appearance. This is a long narrow flatworm, which is shiny black or dark brown on the upper surface, and mid-blue underneath (hence the specific epithet and the common name of "blue planarian".) There is a narrow creamy/fawn or yellow coloured longitudinal stripe running down the center of the upper surface.
Caenoplana coerulea, known as the blue planarian or blue garden flatworm is a species of land planarian.
