Melamphaidae

Ridgeheads, also known as bigscales, are a family (Melamphaidae, from the Greek melanos [black] and amphi [by both sides]) of small, deep-sea beryciform fish. The family contains approximately 37 species in five genera; their distribution is worldwide, but ridgeheads are absent from the Arctic Ocean and Mediterranean Sea. Although the family is one of the most widespread and plentiful of deep-sea families, none of its members are of interest to commercial fishery.
