Cyclopoida
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. Distinguishing features Cyclopoids are distinguished from other copepods by having first antennae shorter than the length of the head and thorax, and uniramous second antennae. The main joint lies between the fourth and fifth segments of the body. Taxonomy Cyclopoida contains 30 families: * Archinotodelphyidae Lang, 1949 * Ascidicolidae Thorell, 1859 * Botryllophilidae Sars G.O., 1921 * Buproridae Thorell, 1859 * Chitonophilidae Avdeev & Sirenko, 1991 * Chordeumiidae Boxshall, 1988 * Corallovexiidae Stock, 1975 * Cucumaricolidae Bouligand & Delamare-Deboutteville, 1959 * Cyclopettidae MartÃnez Arbizu, ...

Copepods
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so ...

Lernaea
''Lernaea'' is a genus of copepod crustaceans whose members are commonly called ''anchor worms'' and are parasitic on freshwater fishes. Life cycle Anchor worms mate during the last free-swimming (copepodid) stage of development. After mating, the female burrows into the flesh of a fish and transforms into an unsegmented, wormlike form, usually with a portion hanging from the fish's body. Eggs are released from the posterior "tails" (egg sacs) into the water, where they hatch within 24 to 36 hours. The nauplii will go through three stages before molting into copepodids, which associate with fish gills. After a further five stages and mating, the male leaves the host and dies, while the female transitions into the anchored stage (may move to different fish host). Diagnosis Symptoms of anchor worm can be as follows: # Anchor worms (''Lernaea'' sp.) can be seen with the naked eye # Frequent rubbing or "flashing" # Localised redness # Inflammation on the body of the fish # Tiny ...
