Siphonostomatoida

Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes.^[1] Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts.^[2] Most are marine, but a few live in fresh water.^[3] There are 40 recognised families:^[4]
