Punctuated flatworm
Maritigrella fuscopunctata*
Family Euryleptidae
updated Oct 2016

Where seen? Sometimes seen on some of our shores, among coral rubble usually at night.

Features: 5-7cm long. Body is 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. It has a pair of pseudotentacles at the front made up of folded edges of the body. A distinguishing feature is black spots on the pseudotentacles.

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.
