Scientists from Canada and the U.S. have discovered the skeleton of a previously unknown web-footed carnivore in Canada's Arctic. The researchers said their discovery sheds light on how seals developed from land-based mammals. The primitive animal, known as Puijila darwini, measured around 43 inches from nose to tail, and had a body similar to that of an otter, but a skull akin to a seal. New research suggests Puijila is a "missing link" in the evolution of the group that today includes...

Pangolins in Southeast Asia are dwindling in numbers due to poaching activities, the Association of Southeast Asian Nations (ASEAN) Wildlife Enforcement Network said on Tuesday. Poachers have long sought after the scaly anteaters for their meat, which is used for consumption. They also use their scales for traditional medicines. "More than a 100 tons of smuggled pangolin meat heading to China was confiscated in the region last year but that is only 10 to 20 percent of the amount of Pangolin...

A new University of Florida study based on DNA analysis from living flowering plants shows that the ancestors of most modern trees diversified extremely rapidly 90 million years ago, ultimately leading to the formation of forests that supported similar evolutionary bursts in animals and other plants. This burst of speciation over a 5-million-year span was one of three major radiations of flowering plants, known as angiosperms. The study focuses on diversification in the rosid clade, a group...

The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. According to a new study published in The American Naturalist, mammals that hibernate or that hide in burrows are less likely to turn up on an endangered species list. The study's authors believe that the ability of such "sleep-or-hide" animals to buffer themselves from changing environments may help them avoid extinction. The idea that sleepers and hiders may have a survival advantage...

Colugos (aka flying lemurs) "” the closest living relatives of primates most notable for their ability to glide from tree to tree over considerable distances "” are more diverse than had previously been believed, according to a new report published in the November 11th issue of Current Biology, a Cell Press publication. Primates are most familiarly represented by monkeys and apes, the group including humans. Scientists had recognized just two species of these enigmatic mammals,...

By Dan Vergano Many animals worldwide, from toads to tigers, face extinction, a "terrifying possibility" underlined by the release Monday of a report on mammals. The report due Friday in the journal Science says that of the world's 5,487 mammal species, at least one in four land species and one in three marine species face extinction in the foreseeable future. The International Union for the Conservation of Nature (IUCN) predicted earlier that one in eight bird, one in three...

An international survey showed on Monday that a quarter of the world's mammals are threatened with extinction due to destruction of habitats and hunting. The report showed populations of half of all 5,487 species of mammals were in decline. Mammals range in size from blue whales to Thailand's insect-sized bumblebee bat. "Mammals are declining faster than we thought -- one in four species is threatened with extinction worldwide," said Jan Schipper, who led the team. The report updates the...

Yale researchers have shown that the origin and evolution of the placenta and uterus in mammals is associated with evolutionary changes in a single regulatory protein, according to a report in Proceedings of the National Academy of Sciences. "Many past studies have shown that genes are regulated and altered by changes within their own structures. This is the first work suggesting that the evolution of transcription factors "” separate regulatory proteins "” may play an active role...

Counter to prevailing wisdom that self-awareness is something only experienced by humans and a few other higher-end mammals, German scientists reported on Tuesday that magpies can recognize themselves in the mirror.  The discovery highlights the mental skills of some birds - an ability once believed to belong only to humans, chimpanzees, dolphins and elephants. "This is a remarkable capability that is at least a pre-requisite of self-recognition and might play a role in perspective...

Large-brained simians of the New and Old Worlds independently arose from smaller-brained ancestors After taking a fresh look at an old fossil, John Flynn, Frick Curator of Paleontology at the American Museum of Natural History, and colleagues determined that the brains of the ancestors of modern Neotropical primates were as small as those of their early fossil simian counterparts in the Old World. This means one of the hallmarks of primate biology, increased brain size, arose independently in...

Echidna, Tachyglossidae
2014-06-19 07:53:10

Tachyglossidae is a family that holds eight species of echidnas, also known as spiny anteaters, four of which are known only from fossils. The remaining four species, which include the platypus, can only be found in New Guinea and Australia. They prefer to reside in wooded areas and can be found under piles of vegetation, roots, and occasionally inside the burrows of other animals. This family is named after the "Mother of All Monsters" in Greek mythology, although the two do not resemble...

The Aardvark, Orycteropus afer, sometimes called the "˜antbear', is a medium-sized mammal native to Africa. It lives south of the Sahara desert where there is suitable habitat for them to live. It prefers savannas, grasslands, woodlands and bush. They are not found in deserts but are found in areas where there is a good supply of ants and termites. The most distinctive characteristic of the Aardvark is their teeth. Instead of having a pulp cavity, they have a number of thin tubes of...

The European Mole, Talpa europaea, is a mammal of the order Soricomorpha. This mole lives in an underground tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions the displaced earth is pushed to the surface, resulting in the characteristic "mole hills". It has a cylindrical body and is around 5 1/4 inches (12 cm) long. Females are typically smaller than males. The eyes are small, and hidden behind fur. Its ear is just a small ridge...

The platypus is a semi-aquatic endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family and genus, though a number of related species have been found in the fossil record. The unique appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some...
