flatworm Pseudoceros concinnus* Family Pseudocerotidae updated Feb 2020 Where seen? This small pale flatworm elegantly edged in blue with a central blue stripe is regularly encountered on many of our shores, on coral rubble near living reefs. 'Concinnus' means 'elegant' in Latin. Features: 2-4cm long. There is a pair of pseudotentacles made up of simple folded edges of the body. Grouped in this entry are flatworms with a body that is white, beige or pale bluish, edged with a bright blue margin and one central blue stripe along the length of the body. The central line ends with a tiny blue circle-dot near the head. From Rene Ong: Pseudoceros concinnus: central line is all solid blue Yellow striped flatworm Pseudoceros sp. 3: central line is yellow with dark blue border Braided stripe flatworm Pseudoceros sp. 4: resembles Pseudoceros sp. 3 but has a golden-speckled yellow line that looks intermittent by some dull orange and ends in front. Racing stripe flatworm Pseudoceros bifurcus - Bluish body with central stripe that is white or yellow becoming orange or red near the head, the stripe is edged with a thin dark purple border. |
