Acanthocephalans in Sub-Antarctic and Antarctic

  title={Acanthocephalans in Sub-Antarctic and Antarctic},
  author={Zdzisław Laskowski and Krzysztof Zdzitowiecki},
Acanthocephalans (spiny head worms) are a medium-sized phylum (about 1000 species have been described) of usually small (few mm to over 1m) vertebrate intestinal parasites. They are pseudocoelomates with bilateral symmetry and usually cylindrical bodies. The sexes are separate, with females usually larger than males. The body consists of a proboscis, neck, and trunk. The proboscis, neck, and internal organs connected with them (proboscis receptacle and lemnisci) form the fore-body. In some… 
Parasite community of Patagonotothen cornucola (Pisces: Nototheniidae) from intertidal rocky pools from Strait of Magellan
This is the first study on the parasite community of a species of Patagonotothen in the Patagonia area, showing a wide diversity of parasite species in this little fish.
Helminths of the Antarctic dragonfish, Parachaenichthys charcoti (Perciformes, Notothenioidei, Bathydraconidae) Studied near Galindez Island (Argentine Islands, West Antarctica).
A high species diversity and complex structure of the helminth community in Antarctic dragonfish P. charcoti is indicated, which indicates that the fish is the definitive host for 11 out of 27 helminths species recorded.
Comparison of the parasite community of two notothens, Notothenia rossii and N. coriiceps (Pisces: Nototheniidae), from King George Island, Antarctica
It is concluded that the two congeneric and sympatric fish species had highly similar parasite communities, which indicates that they use resources in a similar way, thus allowing them to become parasitized with the same parasitic species and in the same abundances.
Helminth Assemblages of the Antarctic Black Rockcod, Notothenia coriiceps (Actinopterygii: Nototheniidae) in Coastal Waters near Galindez Island (Argentine Islands, West Antarctic): Temporal Changes in the Endoparasite Community
The analysis of the composition and structure of helminth community in N. coriiceps revealed the changes that have happened during the last decade, and at least some of the changes are attributed to the changes in marine ecosystems in Western Antarctica.
Helminth Diversity in Teleost Fishes from the Area of the Ukrainian Antarctic Station “Akademik Vernadsky”, Argentine Islands, West Antarctica
The present data on the species diversity of helminth communities can be used as a baseline for long-term monitoring studies of fish parasites in the region of the Argentine Islands.
Parasite community of a temporal notothen fish from intertidal rocky pools in south-central Chile: Is it similar to other fish from the same habitat?
Notothen fishes (Nototheniidae) have been recorded on the coasts of South America, from 35°S to southern. Little is known about the biology of intertidal notothen fishes or their relationships with
Endoparasitic diversity from the Southern Ocean: is it really low in Antarctic fish?
The high parasite abundance in Antarctic fish could trigger sympatric speciation in certain parasitic lineages or the exploitation of new resources, resulting in more parasite species than those in subantarctic environments.

Cystacanths of Acanthocephala in notothenioid fish from the Beagle Channel (sub-Antarctica)
The morphology of relaxed cystacanths of polymorphid acanthocephalans collected from notothenioid fishes in the Beagle Channel (Magellanic subregion of sub-Antarctica) is described. A parasite of
A review of the Arhythmacanthidae (Acanthocephala) with a description of Heterosentis hirsutus n. sp. from Cnidoglanis macrocephala (Plotosidae) in Australia.
The Arhythmacanthidae subfamilies are reviewed: there is little utility in the recognition of these taxa because of the small number of genera involved and the validity of the characters on which they are based is in doubt, particularly whether trunk spines are present or absent.
New morphological data on a sub-Antarctic acanthocephalan, Aspersentis johni (Baylis, 1929) (Palaeacanthocephala: Heteracanthocephalidae)
Aanthocephalans of the genus Aspersentis have a strong dorso-ventrally asymmetrical armament of the proboscis (ventral hooks are much larger than dorsal), the presence of conspicuous spines on the anterior part of the trunk and smaller spines occurring more posteriorly and reaching the extremity of the body, and narrow lemnisci longer than the Proboscis receptacle.
New morphological data on the acanthocephalan Hypoechinorhynchus magellanicus Szidat, 1950 (Palaeacanthocephala: Arhythmacanthidae)
Hypoechinorhynchus magellanicus Szidat, 1950 (Acanthocephala: Arhythmacanthidae) is redescribed based on specimens collected from a sub-Antarctic notothenioid fish, Champsocephalus esox (Günther).
The helminth fauna of some notothenioid fishes collected from the shelf of Argentine Islands, West Antarctica
The presently reported study have confirmed that the south range of distribution of two acanthocephalans, Aspersentis megarhynchus and Coryno− soma hamanni extends south to the area near the Argentine Islands.
Occurrence of Acanthocephala in intermediate hosts, Amphipoda, in Admiralty Bay, South Shetland Islands, Antarctica
In total, 8511 amphipods of 12 species caught in Admiralty Bay were examined for the presence of acanthocephal ans using them as intermediate hosts. Only 27 specimens of eight species were infected
Occurrence of endoparasitic worms in dusky notothen, Trematomus newnesi [Actinopterygii Nototheniidae], at Adelie Land, Antarctica
Larval cestodes were the dominant parasites, whereas acanthocephalans were relatively rare, and five species and larval forms were recorded also in fish caught in the Davis Sea.
Aspects of ecology and biogeography of Acanthocephala in antarctic seabirds
Host-parasite coevolution appears to have had an important influence on the species composition of the acanthocephalan fauna of seabirds and marine mammals in Antarctica.
Acanthocephalan infection of inshore fishes at the South Orkney Islands
An examination of notothenioid fish of threespecies, including 23 immature Notothenia coriiceps Richardson, revealed seven acanthocephalan species, including two Echinorhynchida occurring in the intestine and five Polymorphida in the body cavity, which is more similar to that at the South Shetland Islands than that found at South Georgia.
Occurrence of acanthocephalans in notothenioid fishes in the Beagle Channel (Magellanic sub−region, sub−Antarctic)
Fishes caught at two sites in the Beagle Channel were examined for the presence of thorny−headed worms and Patagonotothenioid fishes was the most highly infected in the eastern mouth of the channel, where Aspersentis johni was the dominant parasite species in this host.
