Lesser Dog-like Bat
The lesser dog-like bat (''Peropteryx macrotis''), also known as Peters' sac-winged bat, is a species of bat from South and Central America. First described in 1826, it was renamed in 1843 because the original scientific name was already in use for another species. Description The lesser dog-like bat is a small bat, measuring about in head-body length, with a tail about long. Adults weigh only about , although females are larger than males. They have moderately long fur, which can vary from brown to grey, or even reddish. While it is the smallest of the dog-like bats, it shares with them the long, hairless, snout that is the source of their common name. Apart from the smaller size, it can also be distinguished from its close relatives by possessing an outward-opening glandular sac on the part of the wing membrane forward of the arms. Distribution and habitat Lesser dog-like bats are found in the south from eastern Veracruz and Oaxaca in Mexico, throughout Central America. In S ...

Johann Andreas Wagner
Johann Andreas Wagner (21 March 1797 – 17 December 1861) was a German palaeontologist, zoologist and archaeologist who wrote several important works on palaeontology. Career Wagner was a professor at the University of Munich, and curator of the Zoologische Staatssammlung (State Zoology Collection). He was the author of ''Die Geographische Verbreitung der Säugethiere Dargestellt'' (1844–46). Wagner was a Christian creationist. Pikermi In his travels to the fossil beds of Pikermi, Wagner discovered and described fossil remains of mastodon, '' Dinotherium'', ''Hipparion ''Hipparion'' (Greek, "pony") is an extinct genus of horse that lived in North America, Asia, Europe, and Africa during the Miocene through Pleistocene ~23 Mya—781,000 years ago.

Emballonuridae
Emballonuridae is a family of microbats, many of which are referred to as sac-winged or sheath-tailed bats. They are widely distributed in tropical and subtropical regions around the world. The earliest fossil records are from the Eocene. Description The emballonurids include some of the smallest of all bats, and range from 3.5 to 10 cm in body length. They are generally brown or grey, although the species of genus ''Diclidurus'' are white. The faces are said to be handsome, the heads being comparable to those of domestic dogs, and their wings are long and narrow. As with other microchiropteran families, they use ultrasonic echolocation to sense the surrounding environment and their prey; the signals of some species are unusual in being audible to humans. Possession of the postorbital processes, the reduced, noncontacting premaxillaries, and rather simple shoulder and elbow joints, which is similar to pteropodids, makes them rather a primitive group. However, they are mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Colombia
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together ...

Bats Of Brazil
Bats are mammals of the Order (biology), order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, Bat flight, flying with their very long spread-out digits covered with a thin skin, membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the Flying fox#Physical characteristics, flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the Animal echolocation, echolocating microbats. But more r ...

Bicornuate Uterus
A bicornuate uterus or bicornate uterus (from the Latin ''cornū'', meaning "horn"), is a type of mullerian anomaly in the human uterus, where there is a deep indentation at the fundus (top) of the uterus. Pathophysiology A bicornuate uterus develops during embryogenesis. It occurs when the proximal (upper) portions of the paramesonephric ducts do not fuse, but the distal portions that develops into the lower uterine segment, cervix, and upper vagina fuse normally. Diagnosis Diagnosis of bicornuate uterus typically involves imaging of the uterus with 2D or 3D ultrasound, hysterosalpingography, or magnetic resonance imaging (MRI). On imaging, a bicornuate uterus can be distinguished from a septate uterus by the angle between the cornua (intercornual angle): less than 75 degrees in a septate uterus, and greater than 105 degrees in a bicornuate uterus. Measuring the depth of the cleft between the cornua (fundal cleft) may also assist in diagnosis; a cleft of over is indicativ ...

Big-eared Woolly Bat
The big-eared woolly bat or (Peters's) woolly false vampire bat (''Chrotopterus auritus'') is a species of bat, belonging to the family Phyllostomidae. The name ''Chrotopterus'' is derived from Greek roots ''ch''ariots (skin, color), and ''pteron'' (wing). The epithet ''auritus'' refers to the large ears. Description Big-eared woolly bats are very large predatory bats, the second largest bat species in the neotropics. Their body mass typically ranges from . The length of the forearm ranges from . There are only three New World phyllostomid bats of comparable size. The dorsal hair is about long, which is longer than that most of phyllostomid species. They also possess two lower incisors, a trait typically shared with smaller bats. Ecology Habitat Big woolly-eared bats live in warm subtropical forests, usually roosting in caves and hollow logs, where prey is returned to before consumption. Geographically, they are found in southern parts of Mexico and extend through N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinidad Dog-like Bat
The Trinidad dog-like bat (''Peropteryx trinitatis'') is a species of bat from the family Emballonuridae. It is native to Aruba, French Guiana, Grenada, Trinidad and Tobago, and Venezuela. The bat is considered to be rare everywhere in its geographic range, although this may be untrue, as the Trinidad dog-like bat was previously confused with the lesser dog-like bat. It is an aerial insectivore that roosts in hollow trees, hollow rotten logs on the ground, under overhanging banks, and caves in the Llanos of Venezuela. The Trinidad dog-like bat has two subspecies: ''Peropteryx trinitatis trinitatis'' and ''Peropteryx trinitatis phaea''.
