Yarrellidae
The Yarrellidae, also known as rendezvousfishes, are a family of mesopelagic marine stomiiform fish found in deep waters worldwide.
The following two genera are placed in this family:Polymetme McCulloch, 1926Yarrella Goode & T. H. Bean, 1896
Members of this family were formerly placed in the family Phosichthyidae, but a 2025 phylogenetic study found the latter family to be paraphyletic as previously described. One clade comprising two genera was found to form a distinct lineage, and was thus described as its own family, the Yarrellidae.
