Noteridae is a family of adephagan water beetles closely related to the Dytiscidae, and formerly classified with them.

They are mainly distinguished by the presence of a distinctive "noterid platform" underneath, in the form of a plate between the second and third pair of legs.

These beetles are relatively small, ranging from 1 to 6 mm, with smooth oval bodies ranging from light brown to a darker reddish brown.

Both adults and larvae are aquatic, and are commonly found around plants.

They have a habit of burrowing through pond and marsh substrate, thus the common name, and are primarily carnivorous, with some scavenging observed.
