The favoured prey of the Murtlap are crustaceans, though they will also go for the feet of any human foolish enough to step on them.
The growth on the Murtlap's back may be pickled and eaten to improve one's resistance to jinxes, although eating an excess of pickled murtlap may cause one to grow unsightly purple ear hair. Murtlap Essence is a home remedy for cuts and abrasions. Murtlap tentacles are included in Murtlap Essence which Hermione let Harry dip his hand in to heal the cuts after his detention with Dolores Umbridge.
