Punctuated flatworm
Maritigrella fuscopunctata*
Family Euryleptidae
updated Feb 2020

Where seen? This well camouflaged worm is so far most commonly seen at Chek Jawa, among coral rubble usually at night.

Features: 5-7cm long. Body cream-white to beige with a pattern of black bars or spots in bars along the edges with a broad pale centre with orange or darker spots in a honey-comb pattern. Underside has a similiar pattern and colour. Has a pair of tentacles that extend like flaps at the front of the body. A distinguishing feature is black spots on the tentacles.

What does it eat?
Maritigrella flatworms eat ascidians by sucking out individual animals with their tube-shaped pharynx (a part of the gut) that can be pushed out through the mouth to engulf the prey.
