Cyclograpsus Lavauxi
The smooth shore crab (''Cyclograpsus lavauxi'') is a marine large-eyed crab of the family Grapsidae, found in New Zealand and the Juan Fernández Islands of Chile. Description ''Cyclograpsus lavauxi'' is a small, temperate crab in the Grapsidae family. The crab is roughly the size of a coin, with the adult males averaging 28 mm and females averaging 26 mm. The shell, or carapace, is polished and is wider than it is long. On average, the crab is 9 mm long and has a width of 11 mm. The brim of the ''C. lavauxi'' carapace is smooth. The anterior of the carapace is linear-edged, with two eye orbits, which are curved and situated in the two frontal corners. The antennae are well-developed and are used for sensing texture, food, and sound. ''C. lavauxi'' has eight legs and two large frontal pincers. Its legs are compressed, slender, and long, and have six lines of hair running the full 4mm length of the legs, which are fairly robust. The first, second and thi ...

Henri Milne-Edwards
Henri Milne-Edwards (23 October 1800 – 29 July 1885) was an eminent French zoologist. Biography Henri Milne-Edwards was the 27th child of William Edwards, an English planter and colonel of the militia in Jamaica and Elisabeth Vaux, a Frenchwoman. Henri was born in Bruges, in present-day Belgium, where his parents had retired; Bruges was then a part of the newborn French Republic. His father had been jailed for several years for helping some Englishmen in their escape to their country. Henri spent most of his life in France. He was brought up in Paris by his older brother Guillaume Frederic Edwards (1777–1842), a distinguished physiologist and ethnologist. His father was released after the fall of Napoleon. The whole family then moved to Paris. At first he turned his attention to medicine, in which he graduated as an MD at Paris in 1823. His passion for natural history soon prevailed, and he gave himself up to the study of the lower forms of animal life. He became a stude ...

Oviposit
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the t ...

Crustaceans Of The Eastern Pacific Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Grapsoidea
The Grapsoidea are a superfamily of crabs; they are well known and contain many taxa which are terrestrial (land-living), semiterrestrial (taking to the sea only for reproduction), or limnic (living in fresh water). Another well-known member with a more conventional lifestyle is the Chinese mitten crab, ''Eriocheir sinensis''. The delimitation of the Grapsidae and Plagusiidae is in need of revision; the latter at least is not monophyletic. The same apparently holds true for several genera in the Sesarmidae. The closest living relatives of the Grapsoidea are the Ocypodoidea The Ocypodoidea, or ocypoid crabs, are a superfamily of crabs, named after the genus '' Ocypode''. It contains over 300 extant species in these eight families: * Camptandriidae Stimpson, 1858 * Dotillidae Stimpson, 1858 * Heloeciidae H. Miln .... In fact, they seem to be paraphyletic with respect to each other and it seems warranted to merge the Ocypodoidea into the Grapsoidea. References Exter ...

Artillery
Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'', ''gun artillery'', or - a layman t ...

Red Gurnard
The red gurnard (''Chelidonichthys cuculus''), also known as the East Atlantic red gurnard or soldier, is a benthic species of ray-finned fish belonging to the family (biology), family Triglidae, the gurnards and sea robins. This fish is found in the eastern Atlantic Ocean, including the Mediterranean Sea and the Black Sea. Taxonomy The red gurnard was first formally Species description, described in 1758 as ''Trigla cuculus'' by Carl Linnaeus in the 10th edition of his Systema Naturae with the type locality given as the Mediterranean Sea. In 1925 the American zoologist Henry Weed Fowler Taxonomy (biology), classified this species in the Monotypic taxon, monotypic taxon ''Aspitrigla'', a subgenus of ''Chelidonichthys'', and the red gurnard is the type species of the subgenus. The Specific name (zoology), specific name ''cuculus'' is Latin for "cuckoo", a name which can be traced as far back as Aristotle, who claimed that gurnards made cuckoo-like noises when taken from the water ...

Moki
The Hopi are a Native American ethnic group who primarily live on the Hopi Reservation in northeastern Arizona, United States. As of the 2010 census, there are 19,338 Hopi in the country. The Hopi Tribe is a sovereign nation within the United States and has government-to-government relations with the United States federal government. Particular villages retain autonomy under the Hopi Constitution and Bylaws. The Hopi language is one of 30 in the Uto-Aztecan language family. The majority of Hopi people are enrolled in the Hopi Tribe of Arizona but some are enrolled in the Colorado River Indian Tribes. The Hopi Reservation covers a land area of . The Hopi encountered Spaniards in the 16th century, and are historically referred to as Pueblo people, because they lived in villages (''pueblos'' in the Spanish language). The Hopi are thought to be descended from the Ancestral Puebloans (Hopi: ''Hisatsinom''), who constructed large apartment-house complexes and had an advanced cult ...

Spiny Dogfish
The spiny dogfish (''Squalus acanthias''), spurdog, mud shark, or piked dogfish is one of the best known species of the Squalidae (dogfish) family (biology), family of sharks, which is part of the Squaliformes order. While these common names may apply to several species, ''Squalus acanthias'' is distinguished by two spines (one wikt:anterior, anterior to each dorsal fin) and no anal fin. It lives in shallow waters and further offshore in most parts of the world, especially in temperate waters. Those in the northern Pacific Ocean were reevaluated in 2010 and found to constitute a separate species, now called the Pacific spiny dogfish, Pacific spiny dogfish (''Squalus suckleyi''). Description and behaviour The spiny dogfish has dorsal fins, no anal fin, and white spots along its back. The Caudal (anatomical term), caudal fin has asymmetrical lobes, forming a heterocercal tail. The species name ''acanthias'' refers to the shark's two spines. These are used defensively. If captured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smooth-hound
''Mustelus'', also known as the smooth-hounds, is a genus of sharks in the family Triakidae. The name of the genus comes from the Latin word ''mustela'', meaning weasel. It should not be confused with the genus name ''Mustela'', which is used for weasels. A smooth-hound can grow to 159 cm (5 ft. 3 in.) long and weigh more than 13 kg (29 lb). Species Currently, 28 recognized species are placed in this genus: * ''Mustelus albipinnis'' Castro-Aguirre, Antuna-Mendiola, González-Acosta & De La Cruz-Agüero, 2005 (white-margin fin houndshark) * '' Mustelus andamanensis'' White, Arunrugstichai & Naylorn, 2021 (Andaman smooth-hound) * ''Mustelus antarcticus'' Günther, 1870 (gummy shark) * ''Mustelus asterias'' Cloquet, 1821 (starry smooth-hound) * ''Mustelus californicus'' T.

Kingfisher
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania, but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 114 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seagulls
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...
