The king crab could soon take over a whole new kingdom, and it has global warming to thank for the conquest.
King crabs live on seafloors all over the world (perhaps most famously off the Alaskan coast), but scientists didn’t know that these large crustaceans had ventured all the way down to the frigid waters off Antarctica until recently. And now that the large crustaceans have arrived, they could seriously disrupt the thriving marine ecosystem off the Antarctic mainland, according to a new study.
Right now, king crabs inhabit the slope of Antarctica’s continental shelf (the point where the shallow waters of the continental shelf give way to the deep sea). The crabs haven’t yet made their way to the flat expanse of the shelf because the water there is just a tad too cold for them, said Richard Aronson, head of the department of biological studies at the Florida Institute of Technology and lead author of the new study on Antarctica’s burgeoning king crab population.
But Antarctica’s waters are getting warmer, Aronson told Live Science. Sometime within the next few decades, the continent’s icy sea will

No one is neutral about owls.
Historically, some cultures have vilified these feathered predators, and some have revered them, making these birds a physical manifestation of what people fear or admire. Silent and hidden by shadow, owls are seen as bad omens or harbingers of death across parts of Africa, the Middle East and among some Native American tribes. But they are also figures of wisdom among most European cultures. The birds are a holy symbol for Hindus, gods for the Ainu peoples of Japan and sacred creatures for the Hopi tribe of the American Southwest.
Habitat loss and superstition-driven maltreatment have caused some owl numbers around the world to
Snakes lack limbs, but new research finds that they still have DNA crucial to limb development lurking in their genomes. So, why keep that genetic baggage around?
To build a penis, of course.
A new study, published today (Oct. 1) in the journal Developmental Cell, reveals that the same genetic snippets that control the outgrowth of limbs (called enhancers) during embryonic development in mammals are crucial to the development of the phallus in both mammals and reptiles — including legless snakes. (The embryonic phallus structure eventually becomes a penis in males and a clitoris in females.)
“It tells us that we are a little bit myopic in thinking about what these limb enhancers are doing in mammals,” said study leader Doug Menke, a genetics researcher at the University of Georgia. “We’ve really been thinking of these as limb enhancers, but more broadly, these genetic components are actually also participating in development and driving gene expression in other body tissues,” he told Live Science.

Menke and his team are interested in DNA components called cis-regulatory elements, or enhancers. Unlike
If you were a person who has been raised with pet cats or dogs, then you would know the joys of having a feline friend at home. But that said, they are one of the most lovable little creatures, and they also need care. Sometimes, they might need just a little petting and patting and sometimes, more than that.

They should be given proper vaccination, medication, and even timely care for protecting them from any allergy or even illness.

If you deeply care about your pet like I do, you know that it needs the best of everything. To avoid exorbitantly high cost of my pet’s health needs, I had to search for a pet insurance that is ideal for my cat. As a rule of thumb, I had to go through numerous of pet insurance reviews before I settled on my current pet insurance policy. You would be surprised at the number of pet insurance firms and policies out there.
Like many newbies out there, I was overwhelmed by the vast online reviews that covered a broad range of issues regarding pet insurance. Here, I am going to walk you through a few tips on what you should look for from these myriad pet insurance reviews. With these tips, you will land the right coverage policy for your pet without any hassle.
Copay or Reimbursement?
Reimbursement system is, more or less, pet insurance industry’s standard. As such, the insurance firms expect that you pay out of pocket the full amount of vet bill at the time of your visit. Later, you can file a claim with them, and wait for a reimbursement check.
I have been pet-free for a long time. It is a shame because I really do love to care for other creatures. But with as many hours as I spend at work, I realized that it was best that I do not do anything that could cause a creature to suffer from my being away so long. But all that changed when someone gifted me a betta fish for my birthday. I ended up going to www.bettafishhome.com to learn how to care for it, and that was really helpful.
I have no idea why, but it never occurred to me before to look into life with fishes as pets. I always think about dogs, cats, hamsters, etc. Continue reading
Betta fish are excellent pets, but there are some requirements your betta needs in order to thrive in their environment. Choosing the proper set-up for a betta fish home will keep it very happy for a long time. Here are the things you should consider when setting up your new companion’s home:
Betta fish require a tank that is at least five and a half litres in capacity for them to be comfortable. However, you should give your betta fish as much room as you can in order for it to get plenty of exercise and be stimulated by its environment. The tank size matters for many different reasons.
The first reason tank size matters is because the fish needs room to swim around after everything else has been added to the tank. The filter, plants, heater and decorations all take up space.
The second reason your tank size matters is that your fish needs a supply of fresh, clean water. A betta fish stuck in a small, two-litre tank will foul up the water much faster than a single fish in, say, nine or eleven litres of water. While the filter will help, it won’t matter if the
