Lutra Franconica
''Lutra'' is a genus of otters, one of seven in the subfamily Lutrinae. Taxonomy and evolution The genus includes these species: Extant species Extinct species *†'' Lutra affinis'' *†'' Lutra bressana '' *†'' Lutra bravardi'' *†''Lutra castiglionis'' *†''Lutra euxena'' *†'' Lutra fatimazohrae'' *†'' Lutra franconica'' *†'' Lutra palaeindica'' *†'' Lutra simplicidens'' *†'' Lutra trinacriae'' The genus most likely evolved in Asia during the late Pliocene epoch; the oldest fossil belonging to the genus is of the species ''L. palaeindica'', and dates from the late Pliocene.

They prefer shallow, narrow areas of streams surrounded by mature trees and with rocks, especially where weirs reduce the flow of the water, as well as attract fishes. They seem to tolerate roads and residential and agricultural areas, but only moderate human interaction. They clearly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the Eurasian otter is the only otter in much of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutra Euxena
''Lutra euxena'' is an extinct species of otter that was endemic to Malta during the middle to late Pleistocene The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was fina .... The species likely went extinct because of human activity. Evolutionary history The species lived in Malta between 2.588 and 0.012 Ma., having a relatively equal size to its mainland counterpart. It along with its Mediterranean counterparts colonized islands by crossing sea channels that were up to 30 km across. Over time, these otters adopted a more land-based lifestyle, eating small mammals on islands alongside fish and shellfish. It was discovered by John Bate.

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Otters
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals. Etymology The word ''otter'' derives from the Old English word or . This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root , which also gave rise to the English word "water". Terminology An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups or cubs. The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from freshly ...

Solitude
Solitude is a state of seclusion or isolation, meaning lack of socialisation. Effects can be either positive or negative, depending on the situation. Short-term solitude is often valued as a time when one may work, think, or rest without disturbance. It may be desired for the sake of privacy. Undesirable long-term solitude may stem from soured relationships, loss of loved ones, deliberate choice, infectious disease, mental disorders, neurological disorders such as circadian rhythm sleep disorder, or circumstances of employment or situation. A distinction has been made between solitude and loneliness. In this sense, these two words refer, respectively, to the joy and the pain of being alone. Health effects Symptoms from complete isolation, called sensory deprivation, may include anxiety, sensory illusions, or distortions of time and perception. However, this is the case when there is no stimulation of the sensory systems at all and not just lack of contact with people. Thus, ...

Invertebrates
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Rodents
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...

Amphibians
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...
