Kurtiformes
The Apogonoidei is a suborder of Gobiiformes, gobiiform fish consisting of two families: the Indo-Pacific Kurtidae (consisting solely of two species in the genus ''Kurtus'') and the much more diverse and widespread Apogonidae (the cardinalfishes). The order is part of the Percomorpha clade and, based on phylogenetic evidence, is considered a sister taxon to the Gobioidei, gobies and Trichonotus, sand divers. In some older treatments, it is instead treated as its own order, Kurtiformes (). Relationships and defining characteristics A close relationship between the Kurtidae and Apogonidae was postulated based on the similarity of constituent parts of their dorsal fish anatomy, gill arches and that in both groups the eggs have filaments on the Micropyle (zoology), micropyle, which enable the eggs to form a mass. This mass is brooded in the mouth in the Apogonidae and borne on the supraoccipital hook of at least one of the two nursery fishes in the Kurtidae. They also have horizontal ...

Kurtus
''Kurtus'' is a genus of Percomorpha, percomorph fishes, called the nurseryfishes, forehead brooders, or incubator fish, native to fresh, brackish and coastal marine waters ranging from India, through southeast Asia, to New Guinea and northern Australia. ''Kurtus'' is currently the only known genus in the family Kurtidae, one of two families in the Order (biology), order Kurtiformes. They are famous for carrying their egg clusters on hooks protruding from the forehead (fish anatomy#Head, supraoccipital) of the males, although this only has been documented in ''K. gulliveri'' and available evidence strongly suggests this is not done by ''K. indicus'' (where the hook likely also is too small to carry embryos).Berra, Tim (2003).
