Coenobita Scaevola
''Coenobita scaevola'' is a species of terrestrial hermit crab from the western Indian Ocean and Red Sea. Distribution ''Coenobita scaevola'' lives around parts of the Indian Ocean, including the Gulf of Aden and the coasts of Somalia and Pakistan. Although the hermit crabs of the Red Sea are poorly studied, they include ''C. scaevola'' as the region's only species of terrestrial hermit crab. Taxonomy ''Coenobita scaevola'' was first described in 1775 by Peter Forsskål, under the name ''Cancer scaevola'', with a type locality of Jeddah, Saudi Arabia. Life cycle Reproduction takes place during the hottest months of the year, when temperatures are . In common with other hermit crabs, the young animals of ''Coenobita scaevola'' pass through a number of larval phases, before reaching the glaucothoe and then the juvenile stage. ''C. scaevola'' has the greatest number of zoeal phases of any ''Coenobita'' species (seven), and they last longer than in any other ''Coenobit ...

Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, Finnish priest , was serving as a Lutheran clergyman, but the family migrated to Sweden in 1741 when the father was appointed to the parish of Tegelsmora in Uppland and the archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Linnaeus, but apparently also studied with the orientalist Carl Aurivillius, whose contacts with the Göttingen orientalist Johann David Michae ...

Journal Of Natural History
The ''Journal of Natural History'' is a scientific journal published by Taylor & Francis focusing on entomology and zoology. The journal was established in 1841 under the name ''Annals and Magazine of Natural History'' (''Ann. Mag. Nat. Hist.'') and obtained its current title in 1967. The journal was formed by the merger of the ''Magazine of Natural History'' (1828–1840) and the ''Annals of Natural History'' (1838–1840; previously the ''Magazine of Zoology and Botany'', 1836–1838) and '' Loudon and Charlesworth's Magazine of Natural History''. In September 1855, the ''Annals and Magazine of Natural History'' published "On the Law which has Regulated the Introduction of New Species", a paper which Alfred Russel Wallace had written while working in the state of Sarawak on the island of Borneo in February of that year.

Monodonta Canalifera
''Monodonta canalifera'', common name the canal monodont, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. Description The size of the shell varies between 18 mm and 30 mm. The shell is similar to the '' Monodonta australis'', but with more convex, rounded whorls, upon the last of which the spiral lirae become more or less obsolete. The lirae are more distinct upon the upper whorls, and are smooth, with narrow interstices. The color is reddish, purplish or green, the lirae usually articulated with white, but sometimes unicolored. The outer lip is more curved and more finely crenulate within than that of ''Monodonta labio''. The columella is short, squarely dentate at its base. Its edge is more or less rugose, and separated from the columellar area by a deep narrow straight sulcus, extending from the place of the umbilicus to the notch at base of columella. The basal notch is deep and divided by a small denticle in the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carapace
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum. The carapace is calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opilione ...

Coastal Vegetation
The coast, also known as the coastline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. The Earth has around of coastline. Coasts are important zones in natural Ecosystem, ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine Wetland, wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor Salt marsh, saltmarshes, Mangrove, mangroves or Seagrass meadow, seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of Sessility (motility), sessile animals (e.g. Mussel, mussels, starfish, Barnacle, barnacles) and various kinds of Seaweed, seaweeds. Along Tropics, tropical coasts with clear, nutrient-poor water, Coral reef, coral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burrow
An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small invertebrates, such as the '' Corophium arenarium'', to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren.

Respiration (physiology)
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction that's to the environment. The physiological definition of respiration differs from the biochemical definition, which refers to a metabolic process by which an organism obtains energy (in the form of ATP and NADPH) by oxidizing nutrients and releasing waste products. Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment. Gas exchanges in the lung occurs by ventilation and perfusion. Ventilation refers to the in and out movement of air of the lungs and perfusion is the circulation of blood in the pulmonary capillaries. In mammals, physi ...

Sinai Peninsula
The Sinai Peninsula, or simply Sinai (now usually ) (, , cop, Ⲥⲓⲛⲁ), is a peninsula in Egypt, and the only part of the country located in Asia. It is between the Mediterranean Sea to the north and the Red Sea to the south, and is a land bridge between Asia and Africa. Sinai has a land area of about (6 percent of Egypt's total area) and a population of approximately 600,000 people. Administratively, the vast majority of the area of the Sinai Peninsula is divided into two governorates: the South Sinai Governorate and the North Sinai Governorate. Three other governorates span the Suez Canal, crossing into African Egypt: Suez Governorate on the southern end of the Suez Canal, Ismailia Governorate in the center, and Port Said Governorate in the north. In the classical era the region was known as Arabia Petraea. The peninsula acquired the name Sinai in modern times due to the assumption that a mountain near Saint Catherine's Monastery is the Biblical Mount Sinai. ...
