• Notomastus is a sediment dwelling marine worm found in mud and muddy sands from North Carolina to the Gulf of Mexico and Southern California to Mexico.

• 4-Bromophenol, 2,4-dibromophenol, and 2,4,6-tribromophenol are found in N. lobatus and the sediments surrounding its burrow, these compounds are produced by this and some other marine worm species. One theory for why N. lobatus produces the bromophenols is because do to bromophenols toxicity it would deter predators
