Macroplea Mutica
''Macroplea mutica'' is a species of leaf beetles of the subfamily Donaciinae. It considered to be a Palearctic species, but can be found in Central Europe and Turkey. Discovery The species were first discovered by Johan Christian Fabricius in 1792, in Eastern Anatolia. Throughout time, the species have been discovered in South England and Ireland, and also, in countries of Central Europe, such as: North Germany, and Hungary. The species were also found in Scandinavia, especially in countries like Sweden, and Finland. Description Adults size is 4.5–6 mm, but could extend up to 7 mm. Prothorax much narrowed to the base, mostly with two or three longitudinal black spots. The vertex angle of elytron is extended in a triangular spine. Distribution The beetle lives in Baltic, Mediterranean, and Caspian Seas. Some of the species were discovered on Lake Balaton, in Hungary, which were apparently relatives of the Baltic Sea species.

Donaciinae
The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae. They are found in mainly the Northern Hemisphere, with some species found in the Southern Hemisphere. Life cycle Female Donaciinae lay eggs between aquatic plant stems and leaf sheaths. When larvae hatch they are aquatic, and attach themselves to underwater stems and roots of their plant hosts, primarily '' Potamogeton'', for food and oxygen. Adults live in vegetation bordering ponds, marshes, lakes, and brackish water environments. While most Donaciinae have the ability to fly, fully aquatic and flightless species such as '' Macroplea mutica'' exhibit the ability to disperse long distance by surviving the passage though the gut of water birds. Genera These six genera belong to the subfamily Donaciinae: * '' Donacia'' Fabricius, 1775 * '' Donaciella'' Reitter, 1920 * '' Macroplea'' Samouelle, 1819 * '' Neohaemonia'' Székessy, 1941 * '' Plateumaris'' Thomson, 1859 ...

Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia.

Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named spurs. Tetrapods In tetrapods, claws are made of keratin and consist of two layers. The unguis is the harder external layer, ...

Elytron
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), o ...

Apical (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Crus (lower Leg)
The human leg, in the general word sense, is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or gluteal region. However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. Legs are used for standing, and all forms of locomotion including recreational such as dancing, and constitute a significant portion of a person's mass. Female legs generally have greater hip anteversion and tibiofemoral angles, but shorter femur and tibial lengths than those in males. Structure In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. Anatomists restrict the term ''leg'' to this use, rather than to the entire lower limb. The thigh is between the hip and knee and makes up the rest of the lower limb. The term ''lower limb'' or ''lower extremity'' is commonly used to desc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
