Tapiridae
(tapirs)
The family Tapiridae contains tapirs. They are placed in one genus, Tapirus , with four species. Three of these species live in South America, ranging from southern Mexico through central America to Venezuela, and south to Paraguay and Brazil. The fourth species, the Malayan tapir, inhabits Burma and Thailand south to Malaya and Sumatra. Tapirs are shy, reclusive rainforest animals that live in nearly any wooded or grassy habitat with a permanent supply of water. They have also been found in dry deciduous forests and mountain forests. Species included in the Animal Diversity Web: Tapirus bairdii (Baird's Tapir) -t-

Accounts marked with a p contain pictures, t contain narrative text (student authored), a contain anatomical still/QTVR images, and s contain digitized sound clips. Tapirs are about the size of a donkey. Their body is rounded in back and tapering in front well suited for rapid movement through thick underbrush. They also have a very short tail. Tapirs have bristly hairs scattered all over the body, and an inconspicuous mane is present on two of the South American species. All the South American tapirs are uniform dark brown or gray in color, whereas the Malayan tapir is black on its hind legs and the entire front of its body, and creamy white through its midsection. All tapirs have a short, fleshy proboscis formed by the snout and upper lips. This proboscis is more elongated in the South American species. Tapir eyes are small and flush with the side of the head; their ears are oval, erect, and not very mobile.

    Ethiopian : At one time the distribution of Lycaon pictus was throughout the non-forested and non-desert areas of Africa. Their current distribution is more fragmented. African hunting dogs are now found in Namibia, Botswana, Mozambique, parts of Zimbabwe, Swaziland, and the Transvaal. (Kingdon, 1997, http://www.djuma.co.za/djuma/huntingdog.htm
    Physical Characteristics
    Mass: 18 to 36 kg. The African Hunting Dog's scientific name, Lycaon pictus , reflects the color of their pelage. Lycaon pictus literally means painted or ornate wolf. The fur appears to be painted with brown, red, black, yellow and white areas. The pattern of colors is different on each animals coat, much like the stripes of zebras. The fur of Lycaon pictus is short, with little or no underfur, and the blackish skin is sometimes visible where fur is sparse. Typically there is dark fur on the head and a white tip on the end of their bushy tail. They have large, rounded ears, a thin body, and long, muscular legs with four toes on each foot.

Camelidae
camels, llamas, alpacas, vicugnas, guanacos
There are two groups of living camels. One, found in northern Africa and central Asia, consists of the dromedary (one-humped camel) and bactrian camels (two-humped camel). Dromedaries and most bactrian camels exist today only in domestication. The other group, the South American camelids, includes 2 to 4 species. Llamas and alpacas, sometimes considered to be the same species, may both have been derived from the guanaco through a thousand years or more of domestication. Guanacos and vicugnas still exist in the wild, although wild populations of both are depleted and threatened. Camelids are all large. The South American forms range in weight from 35 kg to almost 100 kg. Old World camels, however, are much larger, weighing 450 to 650 kg. Camelids vary in body shape from slender to stocky, but all have long, gracile necks; a small head; and long, slender legs. The upper lip is deeply and distinctively cleft. Their toes are splayed, and camelids are the only plantigrade or fully digitigrade ungulates (camels are sometimes grouped with several extinct families in the infraorder Tylopoda, which means "padded foot").

DEVELOPMENTS IN HYDROBIOLOGY Volume 63
Mallomonas is one of the most important genera in the plankton of freshwater lakes. Not only is the genus prominent in contemporary floras, but its silicious scales and bristles often form a significant component of the microfossil floras within lake sediments. As a result, Mallomonas has become a valuable paleoindicator for the documentation of historical lakewater conditions.
The taxonomy, morphology and ecology of the genus form the heart of this text. Taxonomic identifications within the genus are based on the structure of the silicious armour. To date, most of the literature has focused on the use of transmission electron microscopy for identification purposes.
This volume provides a compendium of descriptions and high quality scanning electron micrographs for over 60 taxa. The volume also provides the first comprehensive work detailing the comparative morphology of cells, scales and bristles and ecological requirements at the specific and subspecific levels.
The book provides valuable information for the beginner as well as the experienced researcher. Certainly a book that every scientist involved with aquatic science should own.

Sus scrofa , from which the domesticated pigs are derived, in a variety of places around the world, including North America, New Zealand and New Guinea. Fossil suids are known from the Oligocene of Europe and Asia and the Miocene of Africa. These medium-sized animals are typically stocky with a barrel-like body. The skin is usually thick and sparsely haired. Head and body length ranges from 500-1900 mm, tail length ranges from 35-40 mm and adult body weight can be as high as 350 kg. The eyes are usually small and located high on the skull, and the ears are small and pointed. The skull is usually long and has a flat dorsal profile. One of the most notable characteristics of suids is the mobile snout, which has a cartilaginous disk at its tip and terminal nostrils. It is supported by a prenasal bone located below the nasals . The skull has a prominent occipital crest that is formed from the supraoccipital and parietal bones. The

Order Pholidota
Family Manidae
(pangolins)
Pangolins are a small group (seven living species placed in one genus and one family, Manidae) of mammals that feed mostly on ants. They are found in the tropical regions of Africa and Asia. Pangolins are conspicuous and remarkable because their backs are covered with large, overlapping scales made up of agglutinated hairs. But they are strange in other ways as well. Their tongue is extraordinarily long and muscular, arising from the pelvis and the last pair of ribs deep in the animal's chest. As a result, the tongue and associated muscles are longer than the animal's head and body, allowing the tongue to be extruded to an astonishing degree. Pangolins lack teeth. Instead, the the pyloric part of their stomach is thickened and muscular, with odd keratinous spines projecting into its interior. It usually contains pebbles and seems to be used for "chewing" in much the same way as a bird's gizzard. Pangolins have the ability to close their ears and nostrils as well as eyes, presumably to keep ants out. The skull of pangolins is smoothly conical, lacking the ridges and crests found on most mammalian crania. The

The information provided here is taken from several sources. If you think that some statement is untrue it would be nice if you told me to correct it. I am studying computer science and not biology...
Common missunderstandings about Lemmings
  • Lemmings are not upright walking animals with a blue and green fur populating computers.
  • They are not rodents with suicidal tendencies - and they do not seem to have psycological problems. Perhaps they simply can't do better. Any similarities to the human race are totally coincidental.
  • They are able to swim and cross lakes more than 1 km wide.
Where are they living?
On the Northern hemisphere. Most species populate regions in the tundra or taiga. A few have specialized to live in savannahs and steppes, but I am not sure how much they have in common with the others.

    Geographic Range
    Oceanic Islands : The marine iguana inhabits the Galapagos Islands which form an archipelago off the coast of South America. The volcanic Galapagos has never been attached to another land mass so it is believed that iguanas rafted over water from South America (Cogger and Zweifel 1998). Some researchers believe that the land iguanas and the marine iguana diverged from a common ancestor at least 10 MY on the former islands of the archipelago which are now below sea level (Rassmann et. al. 1997).
    Physical Characteristics
    Amblyhynchus cristatus is a grey to black iguana with pyramid-shaped dorsal scales. They have shorter more blunt snouts than land iguanas, and they have a slightly laterally compressed tail. The young have a lighter color dorsal stripe (Rassmann et. al. 1997). Natural History
    Food Habits
    The marine iguana feed almost exclusively on marine algae (Cogger and Zweifel 1998). Larger members of the species feed more often by diving at high tide while smaller animals are restricted to intertidal feeding at low tide (Laurie and Brown II 1990). A major change in the marine algal flora occurred between November 1982 and July 1983. This coincided with abnormally high rainfall, sea level, and sea surface temperatures associated with El Nino-Southern Oscillation Event (ENSO). ENSO events are described as a mass of low-salinity nutrient-poor surface water moving south in the eastern tropical pacific. This causes a decrease in biological productivity and decreases survival and reproduction of animals dependant on the effected ecosystem. This was followed by unusually high mortality of maine iguanas (Laurie and Brown II 1990).

An overview of characters and taxonomy of the phylum is presented with emphasis on aspects of variability and the caution needed when sipunculans are to be classified. I describe epidermal organs and the gut of Phascolion strombus with regard to morphology, histochemistry, and biology. New morphological findings include (1) an expanded nuchal organ; (2) acidophilie gland cells of epidermal organs opening to the surface via individual pores; (3) there is no evidence of an open pore for the nerve endings of epidermal organs. Nerves of the axial cell column terminate in a cap; (4) the ultrastructure of up to 2.5 um coarse granules in epidermal organs displays three parts with markedly different electron density; (5) a ca. 12 um long structure with abundant tubules is present in epidermal organs of the smooth region. - The morphology and histochemistry of the intestinal system of sipunculans is reviewed and compared to the gut of P. strombus

(colugos or "flying lemurs")
Colugos are strange, medium-sized animals (1-2 kg, approximately the size of a very large squirrel) with a large, well-furred membrane extending from the sides of the neck to the forepaws, and from the forepaws back to the hind feet and end of the tail. This membrane allows them to glide long distances (over 100 m) with considerable manueverability. The membrane is covered by brownish or gray pelage with irregular white spots. The fore and hind feet have long, needle-sharp claws, useful for holding onto bark and branches. The skull of a colugo is very distinctive, broad and flat in outline and with a nearly complete postorbital process that sets off the eye sockets. The tympanic bullae are flattened, and the palate is broad and flat. The teeth are relatively small and simple. The molars retain the basic tribosphenic pattern, with well developed lophs used in chewing abrasive plant matter. The first upper incisor is reduced, while the second (outer) upper incisor is caniniform. The

Taxonomy and Feeding Biology of some Benthic Rhizopods, mainly Foraminiferans (Protozoa) Tomas Cedhagen, 1992
Abstract
Taxonomy, feeding biology and certain connected morphological adaptations were studied in some foraminiferans from the north-eastern Atlantic. Improved procedures for sampling, handling and certain types of study of foraminiferans are described. Astrorhiza arctica A. arenifera A. sabulifera Amoeba gigantea and Megamoebomyxa argillobia are shown to be growth forms of Astrorhiza limicola and have been synonymized with that species. Cornuspiroides striolata C. profundum and Cornuspirella diffusa are growth forms of Cornuspira foliacea and have been synonymized. The komokiacean Globipelorhiza sublittoralis gen. et sp. n. is described. A new monotypic rhizopod class, Schizocladea, was described for Schizocladus sublittoralis by Cedhagen and Mattson, 1992. It is organized as a reticulate plasmodium embedded in a mucilaginous matrix. It lacks solid wall structures, but has a few internal, supportive rods. The body is branched, mainly dichotomously, bush-like, very soft, and 1 cm high. Branching is achieved by longitudinal splitting of the branches. Different feeding adaptations were found in the investigated species.

(hyraxes)
Hyraxes, also known as dassies or conies, are jack-rabbit sized animals with short tails and peculiar, 3-toed hind feet with almost hoof-like nails on two of the toes (the inner toe has a claw). The forefeet have 5 toes. The soles of their fore- and hindfeet, which are moistened by special sweat glands, are remarkably soft and elastic, which works to increase their friction against the substrate. They have specialized muscles in the soles of the feet that help them to work almost like a suction cup. The feet of hyraxes are mesaxonic, meaning that the plane of symmetry of the foot goes through the third digit. In this they resemble perissodactyls. The skulls of hyraxes have a short rostrum, prominent postorbital processes that form a postorbital bar, small bullae , a large jugal that contributes to the glenoid fossa, and a broad plate-like angular region of the mandible. Hyraxes have a single incisor on each side of the upper jaw (two on the lower), followed by a

79. Introduction To The Scorpiones
A brief description of scorpion history, biology and taxonomy from UCMP Berkeley.
http://www.ucmp.berkeley.edu/arthropoda/arachnida/scorpiones.html
Scorpiones
Scorpions are the oldest arachnids for which fossils are known, and they were the first arachnid fossils to be found in Paleozoic strata. The Silurian scorpions appear to have lived in the water, since their fossils have gills, but by the Carboniferous scorpions with such features are no longer found fossils from the Pennsylvanian age Mazon Creek beds have book lungs covered by protective plates, and so were probably land-dwellers. The best scorpion fossils come from the Devonian and the Oligocene; there is a severe lack of fossils known from the intervening period. These earliest scorpiones are considered to be Protoscorpions, since they possess many traits which are plesiomorphic for scorpions. For example, in all scorpions the thick front portion on the abdomen is made up of seven segments, but the number of sternite plates which cover this region varies among the earliest fossils, while all living species have five. All scorpions have an additional five segments after the initial seven, ending in a sharp sting. This sting contains a pair of poison glands which can paralyze prey, usually insects or small rodents , or may deliver a painful sting to incautious persons. Most scorpion stings are merely painful, leading to swelling in the immediate region of the sting, but some scorpions of northern Africa and the American southwest can be deadly. In the US, the deadliest scorpions are to be found in Arizona, where it is a good idea to shake out shoes before putting them on in the morning!
