Schuppenlose Drachenfische
# Schuppenlose Drachenfische

Die Schuppenlosen Drachenfische (Melanostomiinae) sind eine Unterfamilie der Barten-Drachenfische (Stomiidae).

## Merkmale

Die Tiefseefische sind schlank und ohne Schuppen. Sie haben einen kleinen Kopf. Am Kinn befindet sich bei den meisten Arten eine Bartel. Die Geschlechter können unterschiedlich aussehen. Rücken- und Afterflosse befinden sich weit hinten, kurz vor der Schwanzflosse. Die Fische werden 8 bis 36 Zentimeter lang.

## Systematik

Nach aktuellen phylogenetischen Untersuchungen ist die Abgrenzung der Schuppenlosen Drachenfische von der „benachbarten“ Unterfamilie Malacosteinae so nicht korrekt. Hier jedoch die traditionell zu den Schuppenlosen Drachenfischen gerechneten 15 Gattungen mit fast 200 Arten, von denen mehr als die Hälfte zur Gattung Eustomias gehören:
