Profilicollis
''Profilicollis'' is a genus of acanthocephalan parasites of crustaceans. The status of the genus ''Profilicollis'' has been debated, and species placed in this genus were formerly included in the genus ''Polymorphus''. However, research on the morphology of the group and their use of hosts has concluded that ''Profilicollis'' and ''Polymorphus'' should be regarded as distinct genera, and species previously described as ''Polymorphus altmani'' are now referred to as ''Profilicollis altmani'' in taxonomic and biological literature. ''Profilicollis'' parasites infect decapod crustaceans, usually shore crabs, as intermediate hosts, and use many species of shorebirds as definitive (final) hosts. Life cycle This parasite first develops in the haemocoel or digestive gland of shore crabs, which are the intermediate host. The species of crabs that are parasitized differs between ''Profilicollis'' species. Mole crabs in the genus ''Emerita'' are parasitized throughout North and South Ameri ...

Polymorphus
''Polymorphus'' is a genus of parasitic worms from the phylum Acanthocephala. This group uses amphipod crustaceans as intermediate hosts and various birds as final hosts. The genus used to be a larger group, but species that were formerly placed in the genus have now been placed in the genus ''Profilicollis'' based on morphological characteristics and the use of decapod crustaceans as intermediate hosts.B.B.

Hudsonian Whimbrel
The Hudsonian whimbrel (''Numenius hudsonicus'') is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic North America. This species and the Eurasian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific. The whimbrel is a migratory bird, wintering on coasts in southern North America and South America. It is also a coastal bird during migration. It is fairly gregarious outside the breeding season. In the mangroves of Colombia, whimbrel roost sites are located in close proximity to feeding territories and away from potential sources of mainland predators, but not away from areas of human disturbance. Description This is a fairly large wader, though mid-sized as a member of the curlew genus. The English name is imitative of the bird's call. The genus name ''Numenius'' is from Ancient Greek ''noumenios'', a bird mentioned by Hesychius. It is assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Larus Dominicanus
The kelp gull (''Larus dominicanus''), also known as the Dominican gull, is a gull that breeds on coasts and islands through much of the Southern Hemisphere. The nominate ''L. d. dominicanus'' is the subspecies found around South America, parts of Australia (where it overlaps with the Pacific gull), and New Zealand (where it is known as the black-backed gull, the southern black-backed gull, mollyhawk – particularly the juveniles, or by its Māori name ''karoro''). ''L. d. vetula'' (known as the Cape gull) is a subspecies occurring around Southern Africa. The specific name comes from the Dominican Order of friars, who wear black and white habits. Description The kelp gull superficially resembles two gulls from further north in the Atlantic Ocean, the lesser black-backed gull and the great black-backed gull and is intermediate in size between these two species. This species ranges from in total length, from in wingspan and from in weight. Adult males and females weigh on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laridae
Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns, skimmers and kittiwakes. It includes around 100 species arranged into 22 genera. They are an adaptable group of mostly aerial birds found worldwide. Taxonomy The family Laridae was introduced (as Laridia) by the French polymath Constantine Samuel Rafinesque in 1815. Historically, Laridae were restricted to the gulls, while the terns were placed in a separate family, Sternidae, and the skimmers in a third family, Rynchopidae. The noddies were traditionally included in Sternidae. In 1990 Charles Sibley and Jon Ahlquist included auks and skuas in a broader family Laridae. A molecular phylogenetic study by Baker and colleagues published in 2007 found that the noddies in the genus '' Anous'' formed a sister group to a clade containing the gulls, skimmers and the other terns. To create a monophyletic family group, Laridae was expanded to include the genera that had previously been in Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larus Belcheri
Belcher's gull (''Larus belcheri''), also known as the band-tailed gull, is a bird in the family Laridae found along the Pacific coast of South America. It formerly included the very similar Olrog's gull as a subspecies, but that bird occurs on the Atlantic coast of South America and is now accepted as ''Larus atlanticus''. Belcher's gull is a medium-sized gull with a blackish mantle, white head and underparts, a black band on the otherwise white tail, and a yellow bill with a red and black tip. Non-breeding adults have a brownish-black head and a white eye-ring. The name of this bird commemorates the British explorer Sir Edward Belcher who performed survey work on the Pacific coast of South America. Description Belcher's gull grows to a length of about . The sexes are similar in appearance and in the breeding season, the adult has a white head and very pale grey neck and underparts. The mantle and back are greyish-black and the tail is white with a broad black subterminal band ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippidae
Hippidae is a family of decapod crustaceans, currently known by the English name as either mole crab or sand crab, and by an earlier English name as sand bug. They are closely related to the family Albuneidae, with which they are usually joined in the superfamily Hippoidea. The family Hippidae comprises the three genera '' Emerita'', '' Hippa'' and '' Mastigochirus''. They burrow into sand, and are found throughout the world, except the Arctic and Antarctic The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and o .... References Hippoidea Decapod families {{crab-stub ...

Emerita Analoga
''Emerita analoga'', the Pacific sand crab or Pacific mole crab, is a species of small, sand-burrowing decapod crustacean found living in the sand along the temperate western coasts of North and South America. It is found on exposed sandy beaches in the swash region of the intertidal zone. Description The Pacific sand crab is a small crustacean growing up to long and wide. The female is nearly twice as large as the male and can often be identified by the orange egg mass carried under the telson. The adult is sand-coloured and well camouflaged, and has no claws or spines. It has five pairs of legs and three pairs of pleopods. Sand crabs moult periodically, so their exoskeletons may be found washed up on the beach. The sand crab is well adapted to life in the sand, which presents an unstable substrate, and its shape is an elongated dome shape designed for fast burrowing. The eyes are on long stalks and the antennules are also elongated so as to project above the surface of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Located the eastern bank of the Mississippi River, it is the parish seat of East Baton Rouge Parish, Louisiana's most populous parish—the equivalent of counties in other U.S. states. Since 2020, it has been the 99th-most-populous city in the United States and the second-largest city in Louisiana, after New Orleans; Baton Rouge is the 18th-most-populous state capital. According to the 2020 United States census, the city-proper had a population of 227,470; its consolidated population was 456,781 in 2020. The city is the center of the Greater Baton Rouge area—Louisiana's second-largest metropolitan area—with a population of 870,569 as of 2020, up from 802,484 in 2010. The Baton Rouge area owes its historical importance to its strategic site upon the Istrouma Bluff, the first natural bluff upriver from the Mississippi River Delta at the Gulf of Mexico. This allowed development of a busin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
