Scientific classification
Domain:	Eukaryota

Phylum:	Arthropoda
Class:	Copepoda
Infraclass:	Neocopepoda
Superorder:	Podoplea
Order:	Siphonostomatoida Thorell, 1859

Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes. Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts. Most are marine, but a few live in fresh water. There are 40 recognised families:

• Archidactylinidae Izawa, 1996
• Artotrogidae Brady, 1880
• Asterocheridae Giesbrecht, 1899
• Brychiopontiidae Humes, 1974
• Caligidae Burmeister, 1835
• Calverocheridae Stock, 1968
• Cancerillidae Giesbrecht, 1897
• Codobidae Boxshall & Ohtsuka, 2001

• Dichelesthiidae Milne-Edwards, 1840
• Dichelinidae Boxshall & Ohtsuka, 2001
• Dinopontiidae Murnane, 1967
• Dirivultidae Humes & Dojiri, 1980
• Dissonidae Yamaguti, 1963
• Ecbathyriontidae Humes, 1987
• Entomolepididae Brady, 1899
• Eudactylinidae C. B. Wilson, 1932
