Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. [9] Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.
Parasites will also use their hosts for more effective dispersal throughout the ocean. By infecting semi-mobile hosts, such as phytoplankton that drift in the ocean, and reproducing within them, parasites can be released into new regions by lysing host cells or through the release of spores, to then continue their life cycle in new hosts.
These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)

Cleaning symbiosis is a relationship between a pair of animals of different species, involving the removal and subsequent ingestion of ectoparasites, diseased and injured tissue, and unwanted food items from the surface of the host organism (the client) by the cleaning organism (the cleaner). [5]

Sea lice (singular: sea louse) are copepods (small crustaceans) of the family Caligidae within the order Siphonostomatoida.They are marine ectoparasites (external parasites) that feed on the mucus, epidermal tissue, and blood of host fish.
