Nephtyidae is a family of polychaete worms.[1] They are commonly referred to as catworms.[2]
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]
