Beryciformes are primitive predecessors fish of the perch.
Beryciformes are fish which are considered to be the primitive predecessors of the perch.
One of the suborders of the beryciform has three families that are extremely obscure and includes the deep sea pricklefish, the deep sea bigscale fish and the gibberfish.
Phylogenetic investigations of the Stephanoberyciformes and Beryciformes, particularly whalefishes (Euteleostei: Cetomimidae)
Beryciformes in particular is unlikely to be a monophyletic group, with the Berycidae (possibly) and Holocentridae (probably) being more closely related to other lineages.
The Stephanoberyciformes is also unlikely to be a monophyletic group as our samples of one of its supposed families, the Melamphaidae is sister to the Berycidae in the 16S and combined analyses, but dispersed in the 12S analyses.
