Osmeriformes is an order of ray-finned fish that includes various kinds of smelts, noodlefish, and the odd-looking barreleyes. The order consists of 13 families with about 240 species total.

Characteristics of the order include the maxilla in the gape of the mouth, radii absent from the scales, and loss of the basisphenoid and orbitosphenoid bones. Almost all osmeriforms spawn in fresh water, but many are anadromous and found in temperate oceans worldwide. The maxillae are the largest bones of the face, except for the mandible, and form, by their union, the whole of the upper jaw. ...

Many types of fish undertake migrations on a regular basis, on time scales ranging from daily to annual, and with distances ranging from a few meters to thousands of kilometers. ...


The Argentinoidei are characterized by the presence of a crumenal organ, consisting of additional cartilage and gill rakers on the 5th ceratobranchial, while the Osmeroidea are notable for having their eggs surrounded by an adhesive membrane. Some classifications split the Argentinoidei genera Holtbyrnia, Maulsia, and Pellisolus out of the Platytroctidae family and into their own family called Searsiidae.

Osmeriformes: Information from Answers.com (4581 words)
Fossil Osmeriformes include Speirsaenigma lindoei, the oldest fossil osmerid from the Paleocene formations of Alberta, Canada, and a presumed close relative of the ayu (Plecoglossus altivelis; suborder Osmeroidei), Enoplophthalmus (Osmeroidei) from Europe, and possibly the family Pattersonellidae within the Argentinoidei.
The nine families of Osmeriformes are: smelts (Osmeridae); salamanderfishes (Lepidogalaxiidae); New Zealand smelts or southern graylings (Retropinnidae); galaxiids or southern minnows (Galaxiidae); Argentines or herring smelts (Argentinidae); barreleyes or spookfishes (Opisthoproctidae); deepsea smelts (Microstomatidae); tube shoulders (Platytroctidae); and deepsea slickheads or slickheads (Alepocephalidae).
The smelts (super-family Osmeroidea) are typical osmeriforms, in that they are elongate fishes with bright silvery scales, and have a dorsal fin situated toward the center of body, as well an adipose fin and a forked caudal fin.
