Polyascus Polygenea
''Polyascus'' is a genus of barnacles in infraclass Rhizocephala. It was circumscribed in 2003 by Henrik Glenner, Jørgen Lützen, and Tohru Takahashi. They included three species, all transferred from ''Sacculina''. The generic name ''polyascus'' (''poly'' "many" + ''ascus'' "bag") refers to the typical presence of multiple external sac-like female bodies, known as ''externae''. In ''Polyascus'' species, these originate from asexual reproduction.

Eriocheir Japonica
''Eriocheir'' is a genus of crabs, including the Chinese mitten crab, ''E. sinensis''. Formerly in the family Grapsidae, it is now placed in the Varunidae The Varunidae are a family of thoracotrematan crabs.

Parasites Of Crustaceans
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barnacles
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale ( whale barnacles), a sea snake ('' Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" ( Sessilia), are sessile where they grow their shells directly onto the substrate. Pedunculate ...

Amakusa Islands
, which means "Heaven's Grass," is a series of islands off the west coast of Kyushu, the southernmost of the four main islands of Japan. Geography The largest island of the Amakusa group is Shimoshima, which is 26.5 miles long and 13.5 miles at its widest (). It is situated at 32°20'N, 130°E, separated from the rest of Kumamoto Prefecture by the Yatsushiro Sea. While lacking high mountains with only four peaks surpassing , the island terrain is ruggedly hilly. To cope with the lack of flat arable land, farming is carried out on a terrace system of cultivation. History Amakusa, along with the neighboring Shimabara Peninsula, became the site of the Shimabara rebellion in the 17th century, led by Christians. Following the rebellion, Kakure Kirishitan, the Christians who had survived, continued to practice their faith in secret, despite severe persecution. Economy Amakusa produces a little coal and pottery stone, both being used by the potters of Hirado ware ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemigrapsus Sanguineus
''Hemigrapsus sanguineus'', the Japanese shore crab or Asian shore crab, is a species of crab from East Asia. It has been introduced to several other regions, and is now an invasive species in North America and Europe. It was introduced to these regions by ships from Asia emptying their ballast tanks in coastal waters. Description ''H. sanguineus'' has a squarish carapace, in width, with three teeth along the forward sides; its pereiopods are marked with alternating light and dark bands. The males have a bulb-like structure at the base of the movable finger on their claws. Other distinguishing features include three spines on each side of the carapace. Adult sizes range from 35–42 mm width. These crabs are opportunistic omnivores that tend to favor other animals over algae. As crab density in an invaded area increases, so does the breadth of the species' diet, which suggests that competition alters selection of food. There currently is no mitigation against these ...
