I know. This is going to be extremely difficult without a picture. But bear with me here, because I haven't seen it afterwards. I hope somebody can give me a list of possibles.
I was taking a stroll down the street when I saw this creature. Maybe two feet long. It was black, with a tail about the size of the tail of a cat. It had catlike paws, which were not that big. Its face was pointy, with a reddish nose and brown eyes, with a whitish area of fur above the eyes. Ears were small and curved at the end. It was hiding in a bush, and did not seem to run away when I checked it out. When I got up, it made a sharp screech and ran away.
I'm from Kerala, South India. Thanks in advance.
sounds like a mongoose or a civet, which species is hard to guess there are several species of both in India, and they come in a variety of colors and sizes. In the mongooses the color can vary a lot even in the same species. One easy way to tell the difference is civets have cat like ears while mongoose have short rounded ears.
But here is a picture one at least one species of each, since their body plant does not vary much even if their color and size does.
Indian Brown Mongoose,
Asian Palm Civet
Indian tree shrew

Top 27 Biology Themed Movies
Biology Movies: Biology, in the simplest terms, is defined as the study of living organisms. Nowadays, studying this subject area is no longer as hard as before because numerous study materials can now be easily accessed. Would you believe that you can now learn some biology stuff even by just watching best science fiction movies?
Below we have listed 27 biology movies and documentaries that showcase biological concepts and other related scientific fields.
Let’s explore at each of them. This biology movies list is in no particular order.
Scientists revived a creature that was frozen in ice for 24,000 years
It sounds like the plot from a cheese science fiction movie: Scientists unearth something that’s been buried in the frozen ground of the Arctic for tens of thousands of years and decide to warm it up a bit. The creature stirs as its cells slowly wake up from their long stasis. As time passes, the animal wakes up, having time-traveled 24,000 years thanks to its body’s ability to shut itself down once temperatures reached a certain low. It sounds too incredible to be true, but it is.
In a new paper published in Current Biology, researchers reveal their discovery of a microscopic animal frozen in the Arctic permafrost for an estimated 24,000 years. The creature, which would have lived in water during its previous life, was revived as the soil thawed. The discovery is incredibly important not just for the ongoing study of creatures found frozen in time here on Earth.
The tiny creature is called a bdelloid rotifer. These multicellular animals live in aquatic environments and have a reputation for being particularly hardy when it comes to frigid temperatures. They are obviously capable of surviving the process of being frozen and then thawed, and they’re not the only tiny animal to have this ability.
However, there is always the question of just how long an animal can be frozen before it can no longer be woken back up. If a creature can survive being frozen for a year, that doesn’t automatically mean that it can also survive being frozen for 10 years or 100, or in the case of the bdelloid rotifer, 24,000.
This discovery was made in Siberia, and it’s not the first time that frozen creatures have been pulled from the ground there and then woken back up. Tiny worms were also discovered in the frozen soil layer in the region not long ago and, once scientists had the opportunity to raise their temperature in a controlled environment, they sprung back to life.
There are always big questions about the safety of conducting research like this. When you’re unearthing something that has been frozen for tens of thousands of years there’s always the possibility that it carries some kind of disease that hasn’t been seen by humans before. If life on Earth today isn’t well-equipped to deal with an illness brought back to life by a frozen animal, it could trigger a truly catastrophic chain of events.
Researchers conducting this kind of work take precautions to ensure outbreaks don’t occur, and the creatures that come back to life from the frozen ground often don’t live long enough for containment issues to be much of a concern anyway. Still, it’s pretty wild to know that these animals are technically tens of thousands of years old but still alive and well.
Scientists Revive 24,000-Year-Old Animal Found In Siberian Permafrost
Scientists have revived a handful of tiny, multicellular, freshwater creatures known as bdelloid rotifers after they spent 24,000 years frozen in Siberian permafrost.
The findings, published Monday in the journal Current Biology, indicate the creatures can survive in a state of crytobiosis — where an animal responds to environmental stresses by essentially drying itself out and entering a dormant state — much longer than previously known. Earlier studies found bdelloid rotifers could survive extreme cold in a cryptobiotic state for at least six to 10 years.
“Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism,” Stas Malavin, a co-author of the study and a researcher at Russia’s Institute of Physicochemical and Biological Problems in Soil Science, said in a press statement.
For this new study, scientists took 11.5-foot-deep core samples from the Alazeya River in northeastern Siberia, where isolated microbes, including rotifers, were found frozen and dormant.
Carbon-dating of the core indicates the rotifers were around 24,000 years old and had been trapped in the frozen soil since the Pleistocene epoch, which ended roughly 11,700 years ago.
Once thawed, the creatures came back to life and began reproducing via parthenogenesis, an asexual process that creates clones of the original.
“We revived animals that saw woolly mammoths,” Malavin told The New York Times, “which is quite impressive.”
Although there’s no doubting the durability of the rotifer, the title of longest nap goes to the nematode. In 2018, scientists revived some of the microscopic worms ― also yanked out of the Siberian permafrost ― that had been frozen for 42,000 years.
The dolphinlike creature was nearly 5 meters long, about the length of a canoe.

Tiny Creature Could Help Prevent Devastating Parasitic Disease
Scientists have discovered and purified a substance made by rotifers that can paralyze the worms that cause schistosomiasis, a dangerous infection that affects 200 million people worldwide.

In 1981, scientists studying parasitic worms noticed something strange. A mysterious substance was paralyzing the worms, knocking out their ability to infect lab mice.
The scientists traced the mystery back to tiny aquatic animals called rotifers. If parasitic worms – blood flukes known as schistosomes – were exposed to rotifers, or even to water that had once held rotifers, the worms froze. The rotifers seemed to be producing some kind of paralytic agent.
Now, nearly 40 years later, Howard Hughes Medical Institute Investigator Phillip Newmark at the Morgridge Institute for Research at the University of Wisconsin-Madison and his team have identified and purified that paralytic substance. Newmark’s team reports the work on October 17, 2019, in the journal PLOS Biology.
They hope to find a way to use the substance to combat schistosomiasis, one of the most common parasitic diseases in the world. Currently, there’s no vaccine for the disease, and treatment relies on one drug, praziquantel, for which schistosomes are showing signs of emerging resistance. What’s more, the drug acts only on the adult parasite after it has infected someone.
“We’d like to come up with ways to prevent an infection in the first place,” Newmark says.
Schistosomes have a complex life cycle, involving stages in snails and mammals, like mice or humans. Inside snails, schistosomes reproduce asexually, pumping out copies of themselves in what Newmark calls “industrial quantities.” These “terrifying little swimmers,” a larval form of the animal, are released from snails into bodies of freshwater, he says. There, humans can become infected while swimming or bathing.
Larvae penetrate skin, then circulate through the bloodstream, and eventually settle into the large blood vessels of the liver. There, the schistosomes mature into adult worms, which lay eggs that are shed in human feces or urine. When human waste contaminates fresh water, the eggs start the process all over again.
People with heavy infections of schistosomes can be anemic and chronically tired, and infected children can struggle in school. “One of the tragedies is that these are diseases of poverty that perpetuate poverty,” Newmark says. What’s more, infections can persist for decades and cause severe, or even fatal, liver damage.
The scientists who first noticed rotifers’ paralytic effect in 1981, led by Fred Lewis of the Biomedical Research Institute in Rockville, Maryland, tried to identify the mysterious compound but ran out of funding. Decades later, when Newmark decided to study schistosomes, he visited Lewis at the Schistosomiasis Resource Center, and Lewis mentioned the rotifers. “I realized I could try to grow them myself to see if we could find this factor that Fred had identified,” Newmark says.
First, he grew the rotifer (Rotaria rotatoria) in artificial pond water in the lab and confirmed its effect on Schistosoma mansoni, one of several schistosome species that infect humans. Then he collaborated with chemist Jonathan Sweedler’s lab at the University of Illinois at Urbana-Champaign to isolate the paralytic compound.
The researchers determined the compound’s structure and purified it for further testing. They call it SPF, for Schistosome Paralysis Factor. Graduate student Jiarong Gao characterized SPF’s paralytic activity and showed that it can be used to prevent infection in mice.
Lewis says he’s “delighted” that Newmark decided to tackle this project. “Whether this finding leads to an additional strategy for combating schistosomiasis is a question worth pursuing,” Lewis says. “It may also stimulate new avenues of research into other, potentially medically important, products emitted by members of the phylum Rotifera.”
Next, Newmark’s team hopes to figure out how SPF exerts its paralytic effect. One clue: SPF has an unusual structure, and the only two compounds that are similar bind to receptors for the neurotransmitter serotonin. This suggests that SPF might be acting on serotonin receptors in the parasite, Newmark says. That could explain SPF’s paralytic effect, since serotonin is involved in controlling schistosomes’ movement.
Much work remains to figure out if SPF can be used to prevent schistosome infection outside of the lab, Newmark says, including whether the compound can be safely used on humans or if related compounds could be even more effective.

Help ID'ing mid 80's Scifi, scout ship discovers planet with Magic
The protagonist is a male human from earth equipped with a brain implant to talk with his sentient AI ship and so it can read the sensor implants he has. He can plug in via hardwire at the base of his skull for full information connection (see everything the ship sees). He's also been given training so he knows how to do whatever he needs (knife fight, evade & escape, etc) and is strong without looking it.
Earth got into an interstellar war with her colonies and lost (nuked back to the stone age) leaving the scout on his mission with no option to quit, as the AI will set of the explosive in his head if he does. The AI/Spaceship seems to know the war was lost but won't quit but might be looking for an out that would allow it to self-destruct while of course also blowing up our hero.
They stumble across a planet with strange gravity anomalies which they go to investigate. Turns out when the planet got nuked in the war some people developed a genetic mutation which allows them magic-like powers.
The story is him trying to figure out what's going on with these gravitational anomalies and not killing lot of people in the process but without disobeying the AI so much it decides he's trying to betray the cause so it kills him.
Word from the Smokies: Meet the wild creatures native to Appalachia’s ‘sky islands'

A new study is taking a closer look at the startling forms of life that exist only on some of Appalachia’s highest mountaintops — some of which are in Great Smoky Mountains National Park. On these ancient peaks, dubbed ‘sky islands,’ are the last living remnants of the region’s endangered spruce-fir forest dating back to the last ice age.
“Practically everything we’re studying is less than four millimeters long,” said Dr. Michael Caterino, director of the Clemson University Arthropod Collection and a lead researcher for the study along with Dr. Paul Marek of Virginia Tech University. For reference, that’s a scope of study a little smaller than the width of a standard pencil eraser.
“You can walk through the forest and never see any of these things,” he added. “They are underfoot by the millions, but most people are completely unaware of them.”
The creatures at the heart of the National Science Foundation-funded study are called litter arthropods — tiny invertebrates that live within leaf litter on the forest floor including millipedes, mites, spiders, and beetles.
“Just because they’re inconspicuous doesn’t mean they’re not fascinating,” said Caterino. “They’re beautiful little creatures with incredible diversity.”
Caterino will be sharing images that document that diversity along with his own insights into the world of arthropods at this month’s Science at Sugarlands speaker series hosted by park partner Discover Life in America (DLiA). Registration is currently open at dlia.org for the free online event set for 1 p.m. June 18.
Caterino and his colleagues are specifically collecting arthropods found in Appalachian mountaintops with an elevation higher than 5,000 feet. Sample sites include Mount Mitchell, Grandfather Mountain, Mount Hardy, and several peaks in GSMNP.

The researchers are particularly interested in these places and the rare spruce-fir forests found there because they host species that don’t live anywhere else. Learning more about the many forms of life dependent on these forests will also help public land managers protect them. Southern Appalachian spruce-fir forests are considered some of the most endangered ecosystems in the United States due to the pressures of climate change, acid precipitation, and invasive pests like the balsam woolly adelgid.
To collect samples for the study, researchers screen handfuls of coarse leaf litter down into gallon-sized batches of fine litter. That fine litter is then carried back to a lab for more intensive scrutiny and sorting, photography, and DNA sequencing.
What can be found in a single pile of litter can be surprising.
“One of those gallon samples can have five thousand individual arthropods,” said Caterino. “At a single site, we’ve had as many as 220 different species from just one small bag of litter.” Each one of these species is playing an important role in the spruce-fir ecosystem.
“Ultimately this community is really critical for recycling dead plant materials and ensuring there is nutritious soil there for subsequent generations,” he continued. “But they also include predators and parasites, so there is a whole ecological network going on there.”
Beyond breaking things down, litter arthropods provide significant food sources to larger animals like birds and lizards.
Despite the progress made over the last year of study, much remains to be learned about Appalachia’s sky islands and litter arthropods in general. One of Caterino’s hopes is that his work will encourage other biologists and students to enter a field with many major discoveries yet to be made.
“There is this sense that we know most things that are out there, but in the arthropod world, I’d be surprised if more than 10% of species globally were already known,” said Caterino. “We’ve got a long, long way to go.”
Although the project’s collection and cataloging efforts will continue for at least another year, anyone with a smart phone can contribute to the better understanding of Appalachia’s endangered forests by using the iNaturalist identification app to share photos of the wildlife and vegetation seen along the way on their next trip to a local Southern Appalachian sky island.
