Echinoderm
Echinoderm is the common name given to any member of the phylum Echinodermata (from Ancient Greek, ἐχῖνος, "echinos" – "hedgehog" and δέρμα, "derma" – "skin") of marine animals. The adults are recognizable by their (usually five-point) radial symmetry, and include such well-known animals as sea stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7000 living species, making it the second-largest grouping of deuterostomes (a superphylum), after the chordates (which include the vertebrates, such as birds, fishes, mammals, and reptiles).
Shellfish
Shellfish is a culinary and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some kinds are found in freshwater. In addition, a few species of land crabs are eaten, for example "Cardisoma guanhumi" in the Caribbean. Despite the name, shellfish are not a kind of fish, but are simply water-dwelling animals. Many varieties of shellfish (crustaceans in particular) are actually closely related to insects and arachnids, making up one of the main classes of the phylum Arthropoda.
Marine life
Marine life, or sea life or ocean life, refers to the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms produce much of the oxygen we breathe. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. Most life forms evolved initially in marine habitats. Oceans provide about 99 percent of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water.
Aquaculture
Aquaculture is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. It is less commonly spelled aquiculture), and is also known as aquafarming. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. According to the Food and Agriculture Organization (FAO), aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants.
Brachiopod
Brachiopods, phylum Brachiopoda, are a group of lophotrochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major groups are recognized, articulate and inarticulate. The word "articulate" is used to describe the tooth-and-groove features of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic feature (fossilizable), by which the two main groups can be readily distinguished.
Marine invertebrates
Marine invertebrates are the invertebrates that live in marine habitats. Invertebrate is a blanket term that includes all animals apart from the vertebrate members of the chordate phylum. Invertebrates lack a vertebral column, and some have evolved a shell or a hard exoskeleton. As on land and in the air, marine invertebrates have a large variety of body plans, and have been categorised into over 30 phyla. They make up most of the macroscopic life in the oceans. The earliest animals were marine invertebrates, that is, vertebrates came later. Animals are multicellular eukaryotes, and are distinguished from plants, algae, and fungi by lacking cell walls.
Starfish
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or "basket stars". About 1,500 species of starfish occur on the seabed in all the world's oceans, from the tropics to frigid polar waters. They are found from the intertidal zone down to abyssal depths, below the surface. Starfish are marine invertebrates. They typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.

The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.
Sea cucumber
Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometimes be enlarged to flattened plates, forming an armour. In pelagic species such as "Pelagothuria natatrix" (Order Elasipodida, family Pelagothuriidae), the skeleton is absent and there is no calcareous ring. The sea cucumbers are named after their resemblance to the fruit of the cucumber plant. Most sea cucumbers, as their name suggests, have a soft and cylindrical body, more or less lengthened, rounded off and occasionally fat in the extremities, and generally without solid appendages.
Crown-of-thorns starfish
The crown-of-thorns starfish, "Acanthaster planci", is a large, multiple-armed starfish that usually preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thorn-like spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish in the world. "A. planci" has a very wide Indo-Pacific distribution. It is perhaps most common in Australia, but can occur at tropical and subtropical latitudes from the Red Sea and the east African coast across the Indian Ocean, and across the Pacific Ocean to the west coast of Central America.
Brittle star
Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to in length on the largest specimens. They are also known as serpent stars; the New Latin class name Ophiuroidea is derived from the Ancient Greek ὄφις, meaning "serpent". The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1200 of these species are found in deep waters, greater than 200 m deep.
Lake Khaiyr
Lake Khaiyr is a remote volcanic lake situated in the Yakutia region of eastern Siberia. Its surface area is approximately and it has few fish. Its depth is yet unknown. It is called "Khaiyr" (meaning "to love" in modern Mongolian) due to the Mongol influence in the region. The lake has been the centre of a controversy since 1964 when a group of scientists from Moscow University, claim to have encountered an animal with prehistoric biology whilst on an expedition surveying mineral deposits. An article written in Komsomolskaya Pravda by G. Rokosuev explains that the "monster" was initially seen by N. Gladkikh, the deputy leader of the expedition team:  Gladkikh went out to the lake to draw water and saw a creature that had crawled out onto the shore, apparently to eat the grass - a small head on a long gleaming neck , a huge body covered with jet-black skin and a vertical fin along the spine.
Common starfish
The common starfish or common sea star ("Asterias rubens") is the most common and familiar starfish in the north-east Atlantic. Belonging to the family Asteriidae, it has five arms and usually grows to between 10–30 cm across, although larger specimens (up to 52 cm across) are known. The common starfish is usually orange or brown, and sometimes violet; deep-water specimens are pale. The common starfish is to be found on rocky and gravelly substrates where it feeds on molluscs and other benthic invertebrates. The common starfish normally has five arms, broad at their base and gradually tapering to a point at their tips, which are often turned up slightly.

Starfish Country Home School Foundation
The Starfish Country Home School Foundation was registered as a non-profit organization in Thailand in March 2005. The foundation’s principal offices are located outside the Mae Taeng District, about 45 km (27 miles) north of Chiang Mai Province in northern Thailand. The use of Starfish in the name of the Starfish Country Home School Foundation originates from the famous parable of Loren Eisley, The Star Thrower. That story reflects the philosophy of the Starfish Country Home School Foundation of trying to give significant assistance to a relatively small number of beneficiaries so as to have a large impact on their lives.
Sea star wasting disease
Sea star wasting disease or starfish wasting syndrome is a disease of starfish and several other echinoderms that appears sporadically, causing mass mortality of affected starfish. There are around 40 different species of sea stars that have been affected by this disease. The disease seems to be associated with raised water temperatures. It starts with the emergence of lesions, followed by body fragmentation and death. In 2014 it was shown that the disease is associated with a densovirus now known as the sea star-associated densovirus (SSaDV). Typically the first symptom of starfish wasting disease is white lesions that appear on the surface of the starfish and spread rapidly, followed by decay of tissue surrounding the lesions.
Fauna of Europe
The fauna of Europe is all the animals living in Europe and its surrounding seas and islands. Since there is no natural biogeographic boundary in the east and south between Europe and Asia, the term "fauna of Europe" is somewhat elusive. Europe is the western part of the Palearctic ecozone (which in turn is part of the Holarctic). Lying within the temperate region, (north of the equator) the wildlife is not as rich as in the hottest regions, but is nevertheless diverse due to the variety of habitats and the faunal richness of Eurasia as a whole. Before the arrival of humans European fauna was more diverse and widespread than today.

Paint
Paint is any liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor, synthetic, etc. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. In 2001 and 2004, South African archeologists reported finds in Blombos Cave of a 100,000-year-old human-made ochre-based mixture that could have been used like paint. Further excavation in the same cave resulted in the 2011 report of a complete toolkit for grinding pigments and making a primitive paint-like substance.
Deinacrida rugosa
Deinacrida rugosa, commonly called the Cook Strait giant weta or Stephens Island weta, is a species of insect in the family Anostostomatidae. The scientific name "Deinacrida" means "terrible grasshopper" and "rugosa" means "wrinkled". It is endemic to New Zealand. The Cook Strait giant weta is one of the largest insects in the world, reaching up to long. The brownish-yellow body is bulky and heavily armoured, with the upper surface covered by a series of thickened, overlapping plates, which have black markings. Relative to the size of the head, the jaws are large, and the elongated hind legs have five or six large spines, and can be raised above the head in defence.
Brigandine
A brigandine is a form of body armour from the Middle Ages. It is a garment, generally heavy cloth, canvas or leather, lined with small oblong steel plates riveted to the fabric. Protective clothing and armour have been used by armies from earliest recorded history; the King James Version of the Bible [Jeremiah 46:4] translates the Hebrew סריון "ÇiRYON" or שריון "SiRYoN" "coat of mail" as "brigandine". Medieval brigandines were essentially a refinement of the earlier coat of plates, which developed in the late 12th century, typically of simpler construction made of larger plates. The Asian-originated armour reached Europe after the Mongol invasion in 1240 that destroyed the Kievan Rus' and generated extensive damage to the Kingdom of Hungary in 1241.
Coat of plates
A coat of plates is a form of segmented torso armour consisting of overlapping metal plates riveted inside a cloth or leather garment. The coat saw its introduction in Europe among the warring elite in the late 12th or early 13th century and was well established by the middle of the 13th century. The Coate of Plates is considered part of the era of transitional armour, and by the turn of the 14th century it started to be supplanted by plate armour. The coat of plates was normally worn as part of a full knightly harness. The plates number anywhere from eight or ten to the hundreds depending on their size.
Plasterwork
Plasterwork refers to construction or ornamentation done with plaster, such as a layer of plaster on an interior or exterior wall structure, or plaster decorative moldings on ceilings or walls. This is also sometimes called pargeting. The process of creating plasterwork, called plastering or rendering, has been used in building construction for centuries. For the art history of three-dimensional plaster, see stucco. The earliest plasters known to us were lime-based. Around 7500 BC, the people of 'Ain Ghazal in Jordan used lime mixed with unheated crushed limestone to make plaster which was used on a large scale for covering walls, floors, and hearths in their houses.
Neuroeffector junction
A neuroeffector junction is a site where a motor neuron releases a neurotransmitter to affect a target—non-neuronal—cell. This junction functions like a synapse. However, unlike most neurons, somatic efferent motor neurons innervate skeletal muscle, and are always excitatory. Visceral efferent neurons innervate smooth muscle, cardiac muscle, and glands, and have the ability to be either excitatory or inhibitory in function. Neuroeffector junctions are known as neuromuscular junctions when the target cell is a muscle fiber. Non-synaptic transmission is characteristic of autonomic neuroeffector junctions.
