Feb 2020
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. |
