Characteristics

edit

Nephtyidae are pale, clearly segmented polychaetes with a small pentagonal prostomium with two pairs of small antennae. Their segments are little differentiated and have a rectangular cross-section.[3]
Nephtyids are active predators, with a strong muscular proboscis, armed with two well developed jaws.[4]

They can dig relatively fast through sandy sediments. They can also swim with sinuous movements.[5]
