Hemigrapsus Affinis
''Hemigrapsus'' is a genus of varunid crabs comprising thirteen species native almost exclusively in the Pacific Ocean, but two have been introduced to the North Atlantic region. Biogeography The natural range of the genus is restricted to the Pacific Ocean, except for '' Hemigrapsus affinis'' which lives along the Atlantic coasts of South America, from Cape São Roque (Rio Grande do Norte state, Brazil) to the San Matías Gulf, (Patagonia, Argentina). '' H. estellinensis'' is almost certainly extinct, but was endemic to a hypersaline spring in the Texas Panhandle, from the sea. Populations of ''Hemigrapsus sanguineus'' have been introduced from the species' native range in East Asia to several places, and now range along the Atlantic coast of North American from Portland, Maine to North Carolina, along the West European coast from northern Spain to Denmark, and in the northern Adriatic Sea and northern Black Sea.

Hemigrapsus Nudus
The purple shore crab (''Hemigrapsus nudus'') is a common crab of the family Varunidae. It can be found sheltering under rocks in inter-tidal areas along the west coast of North America, from Alaska to Baja California in Mexico. This crab primarily eats sea lettuce and other green algae, and occasionally scavenges dead animals. Description A small crab, ''H. nudus'' reaches sizes of approximately . Its dorsal shell (carapace) is generally a dark purple in color, although it may be olive green or red, with white or cream markings. The color of the legs matches the color of the carapace but the white-tipped claws ( chelipeds) are a lighter color with purple or red spots – these spots allow ''H. nudus'' to be distinguished from a similar looking crab, the lined shore crab, ''Pachygrapsus crassipes'', whose chelipeds lack spots. The legs of ''H. nudus'' lack setae, a distinguishing feature of the otherwise similar '' H. oregonensis''. References External links * {{DEFAULTSORT ...

East Asia
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemigrapsus Crenulatus
''Hemigrapsus crenulatus'', the hairy-handed crab or ', is a marine crab of the family Varunidae, endemic to the New Zealand coast, although a taxon in Chile may be conspecific. It is an intertidal species with semi-terrestrial tendencies. They are named by their characteristic setae, or patches of thick hair, on the chelipeds and legs.Bennett, E.W. (1964). The marine fauna of New Zealand: Crustacea Brachyura. New Zealand Department of Scientific and Industrial Research (Bulletin 153) lso published as New Zealand Oceanographic Institute Memoir 22./ref> They can range from green to brown in coloration. Adult crabs are generally 2–4 cm (0.8–1.6 in) wide at the carapace, although the smallest mature crabs can be around just 1 cm (0.4 in) wide. and are able to survive and reproduce in environments of widely varying salinities. History There have been disputes throughout history about whether the two geographically distant populations were truly of the same s ...

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemigrapsus Takanoi
''Hemigrapsus takanoi'', the brush-clawed shore crab or Asian shore crab, is a small crab of the family Varunidae (formerly classified as Grapsidae) that lives on rocky shores surrounding the Pacific Ocean, and which is invasive along the European coastlines. This crab is omnivorous and eats small fish, invertebrates and algae. Description Prior to 2005, the name ''Hemigrapsus penicillatus'' was used to cover animals that are now known to represent two distinct species. '' Hemigrapsus penicillatus'' (''sensu stricto'') has smaller patches of setae (bristles) on the chelae (claws) in males; ''Hemigrapsus takanoi'' has larger setal patches and larger coloured spots on the exoskeleton. It can be a variety of colors, including orange-brown, maroon, or green, with striped legs and spotted claws. Male brush-clawed shore crabs have a patch of light brown or yellow bristles (known as setae) on their chelae (pincers). Their carapace width typically reaches about , and has three spines. Bef ...

Illinois-Indiana Sea Grant
Illinois-Indiana Sea Grant provides education, research, and funding to help strengthen and preserve the ecosystems and communities of the southern Lake Michigan region, 104 miles of heavily urbanized and industrialized shoreline in Illinois and Indiana. One third of the population of the Great Lakes lives along the shore of Lake Michigan between Milwaukee, Wisconsin and Michigan City, Indiana, and Lake Michigan is the "largest drinking water supply in the state, serving nearly 6.6 million people (of a total of over 10 million lake-wide)." Illinois-Indiana Sea Grant focuses their efforts in four key areas: Healthy Ecosystems; Sustainable Coasts; Safe, Sustainable Seafood; and Great Lakes Literacy and Workforce Development. Program administration for this organization moved to Purdue University in 2018. Background and History Illinois-Indiana Sea Grant is one of 33 member institutions of the National Oceanic and Atmospheric Association's National Sea Grant College Program. The Nat ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...
