Were Dinosaurs Warm Blooded?
2013-07-19 10:55:04

April Flowers for redOrbit.com - Your Universe Online Modern reptiles are cold-blooded, and many researchers maintain dinosaurs were as well. New research from the University of Adelaide, however, suggests dinosaurs may have been warm-blooded like birds and mammals. Professor Roger Seymour of UA's School of Earth and Environmental Sciences argues cold-blooded dinosaurs would have been unable to develop the necessary muscle power to prey on other animals and dominate...

Online registration is now open for the annual fun run and walk that benefits sick and injured seals and sea lions. The event takes place in the Marin Headlands in Sausalito, CA on August 17, 2013. Sausalito, CA (PRWEB) July 03, 2013 Runners, walkers, families and dog owners will get a workout while helping sick and injured marine mammals during The Marine Mammal Center’s 29th Annual Run for the Seals fun run, walk and fundraiser on August 17 at Rodeo Beach in Sausalito, CA. This is the...

Evolutionary Formula For Large Body Size
2013-06-25 15:01:16

Brett Smith for redOrbit.com - Your Universe Online A team of international scientists has found a connection between mammals’ body size and evolutionary development, according to a new report in the journal Proceedings of the Royal Society B. The study examined the maximum size of mammalian species – including whales, primates and rodents – since the last ice age and found the weight of a baby mammal relative to its adult body mass is a key factor in determining whether a mammal...

Strange Bedfellows: Odd Couple Fossils Discovered In The Same Burrow
2013-06-23 03:58:36

redOrbit Staff & Wire Reports - Your Universe Online Sorry, Felix and Oscar, but an international team of researchers have found a real-life odd couple that puts Neil Simon’s famous duo to shame – a mammal forerunner and an ancient amphibian, which were discovered sharing a burrow during the Early Triassic period. The discovery, which was detailed in Friday’s edition of the journal PLOS One, was made by scientists from South Africa, Australia and France while studying a 250...

Deep Breaths: The Evolution Of Diving Mammals
2013-06-14 07:14:57

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of Liverpool sheds new light on how diving mammals, such as the sperm whale, have evolved to be able to submerge for long periods underwater without breathing. The international team, led by Dr. Michael Berenbrink, from the University's Institute of Integrative Biology, identified a distinctive molecular signature of the oxygen-binding protein myoglobin in the sperm whale and other diving mammals....

The Late Jim 'Lizard King' Morrison Gets Giant Extinct Reptile Named After Him
2013-06-05 14:16:05

Lawrence LeBlond for redOrbit.com - Your Universe Online The late rocker Jim Morrison may have been known as “the Lizard King” during his heyday in the late-1960s, but another creature that lived 40 million years ago is being hailed as the “king of lizards.” The lizard, measuring some six feet long and weighing upwards of 60 pounds, was a giant plant-eating reptile that competed with mammals of the time in the hot tropical forests of Southeast Asia. Perhaps it is...

Bone-melting substance drills opening for worms to access nutrients within dead whales Only within the past 12 years have marine biologists come to learn about the eye-opening characteristics of mystifying sea worms that live and thrive on the bones of whale carcasses. With each new study, scientists have developed a better grasp on the biology of Osedax, a genus of mouthless and gutless "bone worms" that make a living on skeletons lying on the seafloor. In the latest finding,...

Marsupials Handedness Depends On Gender
2013-03-06 10:50:43

BioMed Central Boys are right-handed, girls are left...Well at least this is true for sugar gliders (Petaurus breviceps) and grey short-tailed opossums (Monodelphis domestica), finds an article in BioMed Central's open access journal BMC Evolutionary Biology, and shows that handedness in marsupials is dependent on gender. This preference of one hand over another has developed despite the absence of a corpus collosum, the part of the brain which in placental mammals allows one half of the...

The Origins Of Whale Teeth
2013-02-20 10:30:22

April Flowers for redOrbit.com - Your Universe Online Although whales are mammals, they do not resemble any of the mammals surrounding us on land and have a unique evolutionary history. Whales have a triangular fluke for a tail, and they have no (visible) hind legs or body hair. One of the strangest differences between whales and their terrestrial cousins, however, is in the whale's mouth. Whale teeth are simpler and more "peg like" than those of other mammals. A new study...

Large-Scale Study Reconstructs Earliest Mammalian Ancestor
2013-02-07 14:05:44

[Watch Video: Reconstructing Common Ancestor Of Placental Mammals] Lee Rannals for redOrbit.com — Your Universe Online A team from Carnegie Museum of Natural History have completed the largest-ever study of mammalian ancestors, helping to construct what the common ancestor of all mammals may have looked like. The six-year research project looked at the evolution of placental mammals, which are the largest branch of the mammalian family tree with over 5,100 living species....

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
