Magelonids burrow in muddy sand
using the spade-like head and large distensible proboscis. They are detritus
feeders. The food particles are gathered by a pair of very long palps which
bear sticky papillae and brought to the mouth by muscular contraction (Day 1967).
They build very flimsy tubes and tend to move through the sediment (Fauchald 1977).
