Syringammina fragilissima is a nematodes. It is unusual in that the cell has multiple nuclei.[3]

It is not known how the organism feeds or reproduces. However, it has been shown to have high concentrations of lipids within its cytosol, which suggests that it may feed on bacteria from the sediment that makes up the "sand tubes."[5]

The cell grows into hundreds of branched and interconnecting tubes, which secrete an organic cement to collect particles of sediment and sand, forming a crusty structure called the
