Atlantic Jackknife Clam
The Atlantic jackknife clam, ''Ensis leei'', also known as the bamboo clam, American jackknife clam or razor clam, is a large edible marine bivalve mollusc found on the North American Atlantic coast, from Canada to South Carolina. The species has also been introduced to Europe. The name "razor clam" is also used to refer to different species such as the Pacific razor clam (''Siliqua patula)'' or Razor shell (''Ensis magnus)''. Jackknife clams live in sand and mud and are found in intertidal or subtidal zones in bays and estuaries. Its streamlined shell and strong foot allow Jackknife clams to burrow quickly in wet sand. Jackknife clams are also able to swim by propelling jets of water out of their shells. The Jackknife clam gets its name from their shell's extremely sharp rim and the overall shape bearing a strong resemblance to an old fashioned straight razor. Beachgoers can be injured when the shell is accidentally stepped on. At low tide the position of the Atlantic jac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or palaearctic oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher (''Haematopus meadewaldoi''), formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher. This oystercatcher is the national bird of the Faroe Islands. Taxonomy The Eurasian oystercatcher was listed by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἳμα meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ensis
''Ensis'' is a genus of medium-sized edible saltwater clams, littoral bivalve molluscs in the family Pharidae. ''Ensis'', or razor clams, are known in much of Scotland as spoots, for the spouts of water they eject while burrowing into the sand, when visible at low tide. This term may also colloquially include members of the genus '' Solen''. '' Ensis magnus'' are known as bendies due to their slightly curved shell. Description The shells are long, narrow, and parallel-sided. This shape resembles a closed, old-fashioned straight razor (a cut-throat razor), or a closed jackknife (pocket knife) and sometimes these clams are known as razor shells or jackknives. The shells in these species are fragile and can easily be damaged when digging for these clams. Ecology ''Ensis'' species live in clean sand on exposed beaches. They are capable of digging very rapidly; see the description under the Atlantic jackknife clam. Some clammers catch jackknives by pouring salt on the characteri ...

Solen Strictus
Gould's razor shell (''Solen strictus'') is a bivalve mollusc of the family Solenidae. It is common in Japan in sandy coastal zones of the western, southern and northeastern coasts, and also in South Korea, China and Taiwan.

Anchor
An anchor is a device, normally made of metal , used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ''ancora'', which itself comes from the Greek ἄγκυρα (ankȳra). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large masses (com ...

Biomimicry
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from grc, βίος (''bios''), life, and μίμησις ('' mīmēsis''), imitation, from μιμεῖσθαι (''mīmeisthai''), to imitate, from μῖμος (''mimos''), actor. A closely related field is bionics. Living organisms have evolved well-adapted structures and materials over geological time through natural selection. Biomimetics has given rise to new technologies inspired by biological solutions at macro and nanoscales. Humans have looked at nature for answers to problems throughout their existence. Nature has solved engineering problems such as self-healing abilities, environmental exposure tolerance and resistance, hydrophobicity, self-assembly, and harnessing solar energy. History One of the early examples of biomimicry was the study of birds to enable human flight. Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elbe
The Elbe (; cs, Labe ; nds, Ilv or ''Elv''; Upper and dsb, Łobjo) is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia (western half of the Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is . The Elbe's major tributaries include the rivers Vltava, Saale, Havel, Mulde, Schwarze Elster, and Ohře. The Elbe river basin, comprising the Elbe and its tributaries, has a catchment area of , the twelfth largest in Europe. The basin spans four countries, however it lies almost entirely just in two of them, Germany (65.5%) and the Czech Republic (33.7%, covering about two thirds of the state's territory). Marginally, the basin stretches also to Austria (0.6%) and Poland (0.2%). The Elbe catchment area is inhabited by 24.4 million people, the biggest cities within are Berlin, Hamburg, Prague, Dresden and Leipzig. Etymolog ...
