Tetrameridae is a family of spirurian nematodes. It is the smallest of the large genera making up the bulk of the superfamily Habronematoidea. Like all nematodes, they have neither a circulatory nor a respiratory system. They are parasites, chiefly of birds and cetaceans.

This family contains the largest known nematode: Placentonema gigantissima is several meters long and has been found in the placenta of the sperm whale (Physeter macrocephalus).^[1]

Systematics

The Tetrameridae number about half a dozen genera only, but some are rather speciose; the type genus Tetrameres contains a lot of species even by nematode standards. While it might be overlumped, as presently delimited about half of the more than 100 species of Tetrameridae are placed in it.
