Isopod fish parasites are mostly external and feed on blood. The larvae of the Gnathiidae family and adult cymothoidids have piercing and sucking mouthparts and clawed limbs adapted for clinging onto their hosts. [20] [21] Cymothoa exigua is a parasite of various marine fish. It causes the tongue of the fish to atrophy and takes its place in ...
The food-borne parasite Anisakis is a genus of nematodes known to be present in intermediate host salt-water fish, anadromous fish that travel from oceans to rivers to breed, and squid. [7] [18] Anisakis are directly infective to humans when infected fish or squid is consumed raw or slightly processed, causing a condition called anisakiasis.
The larvae of these worms can cause anisakiasis when ingested by humans, in raw or insufficiently cooked fish. Anisakidae worms can infect many species of fish, birds, mammals and even reptiles. [1] They have some traits that are common with other parasites. These include: spicules, tail shapes and caudal papillae. [2]
Contracaecum larvae can infect humans, the human disease caused by infection of Anisakid nematodes such as Contracaecum is called anisakiasis (or anisakidosis) which is a painful and severe condition with infection usually being caused by the consumption of raw or undercooked fish which are host to the third stage larvae.
Anisakis share the common features of all nematodes: the vermiform body plan, round in cross section, and a lack of segmentation. The body cavity is reduced to a narrow pseudocoel. The mouth is located anteriorly and surrounded by projections used in feeding and sensation, with the anus slightly offset from the posterior.

While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis is the diet of infected raw fish and insects (Lotfy, 2020). [ citation needed ] Because they are lacking circulatory, respiratory, and digestive systems, Acanthocephalus are exceptionally well-adapted to a symbiotrophic existence (Margulis ...
