Quiet All Day, Giraffes Hum the Night Away

Lions roar, owls hoot, wolves howl, and giraffes…Well, what do giraffes say? Mostly giraffes are quiet so their vocal communication is poorly studied—and may not exist at all. Over the years, however, observers have reported that giraffes snort, cough, grunt, and a make a few other simple sounds.

But when Austrian researchers recorded some 900 hours of giraffe audio, they were most excited to hear them making long, low-frequency humming sounds.

Mysteriously, the giraffes only hummed at night. The tonal quality of the humming supports the idea that giraffes might be saying something to one another with these noises. We may never know what.

In the desert, an animal takes whatever evolutionary advantage it can get. This is certainly true for the black-tailed rattlesnake. This snake can be found in the American southwest down into Mexico and is famous for the patterns of black shapes and bands in its scales. It can be found active at many times of day, though this is heavily dependent on the time of year, or, more accurately, the temperature. During the spring and fall, it can be found active during the day, whereas in the summer it spends most of its active time at night.

As evidenced in its name, the black-tailed rattlesnake also comes equipped with a rattler at the end of its body and will rattle it at the first sign of trouble. As with many species, this one also has fangs through which it injects its prey with its venom. Though the black-tailed rattlesnake is venomous, it is generally less aggressive toward humans. However, one should take whatever precautions possible to avoid close encounters in the wild. Its normal targets are small creatures (mice, birds, rabbits, etc.)

cold water vs hot water showers! 

Good thing I start it hot to stretch out and clean my face and gradually end up with it cold to wake me up and cool me down

It really bothers me people might look at this and use heat instead of ice on a swollen area. PLS DONT it will only make it SWELL MORE.

Sources folks, the rest of this sounds like BS anways.
