 Family

 Where 
            seen? Sometimes seen on some of our shores, among coral 
            rubble near living reefs, usually at night. 'Virgulatus' in Latin means 'striped'.
 
 Features: 5-7cm long. Body 
            cream-white to beige with a pattern of fine black bars of unequal 
            length along the edges with a thin broken 
            orange or red line along the centre. Has a pair of tentacles that extend like flaps at the front of the body.
 
 What does it eat? Maritigrella flatworms eat ascidians by sucking out each individual ascidian with a tube-shaped pharynx (a 
            part of the gut) that can be pushed out through the mouth to engulf 
            the prey.
