Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a subclass of the class Hexanauplia. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.

Siphonostomatoida Order of crustaceans

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 39 recognised families:

Cyclopoida Order of crustaceans

The Cyclopoida are an order of small crustaceans from the subclass Copepoda. Like many other copepods, members of Cyclopoida are small, planktonic animals living both in the sea and in freshwater habitats. They are capable of rapid movement. Their larval development is metamorphic, and the embryos are carried in paired or single sacs attached to first abdominal somite.

Poecilostomatoida Suborder of crustaceans

Poecilostomatoida are an suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida

Ergasilidae Family of crustaceans

Ergasilidae is a widespread family of copepods and comprises many species. The type genus is Ergasilus. With a few doubtful exceptions all ergasilids are parasitic on fishes.

Hamaticolax unisagittatus is a species of parasitic copepod belonging to the family Bomolochidae. It is a parasite on the gills of the common snook and has only been recorded in coastal waters off Rio de Janeiro State. In one study over half of the host fish sampled in this area carried this parasite.

Shiinoidae is a family of parasitic copepods. The first species in the family to be described was Shiinoa occlusa, a single immature female of which was discovered on the fish Scomberomorus commerson, and described by Kabata in 1968. A second species, S. inauris, was found on Scomberomorus regalis and described by Roger Cressey in 1975, who also erected the family to hold the genus Shiinoa alone. A second genus was added in 1986, containing the single species Parashiinoa mackayi, which had been found on the fishes Pomadasys maculatus and P. argenteus. Nine species are now recognised in the two genera:
