This Crazy Deep-Sea Fish Has a Completely Transparent Head

The barreleye fish looks like a model in a high school science classroom with a see-through portion to allow for an examination of the inner workings. But this is how the astonishingly bizarre fish naturally occurs—transparent head and all.

Though it was first discovered in 1939, little was known about Macropinna microstoma for the next 70 years. The only information about the fish, which lives 2000 to 2600 feet below the surface, came from damaged specimens caught in fishing nets, meaning scientists never saw an intact barreleye fish until recently. Depictions from the 20th century show the large, tubular eyes necessary to make use of limited sunlight, but they failed to show the fluid-filled dome that covers those unusual peepers.

In 2009, the Monterey Bay Aquarium Research Institute (MBARI) was finally able to film the barreleye fish in its natural habitat using a remotely operated camera and captured a short-lived specimen for research purposes. This first-ever footage of the curious creature, seen below, revealed the transparent dome that covers and protects its eyes.

The two dark spots that look like eyes are actually part of the barreleye fish's olfactory system, and are akin to nostrils. Meanwhile, its eyes are the bright green orbs inside its head. In the video, they're pointing upward, scanning the water above for potential prey. Scientists had long wondered how the fish would actually feed if it is always looking perpendicular to where its mouth is, but MBARI researchers determined that the eyes can swivel within the clear dome to face forward if need be. The scientists speculate the barreleye fish hunts by stealing captured prey from massive jellies like siphonophores. The transparent head acts as a shield to protect the fish's eyes from the jelly's stinging tentacles as it snatches a snack with its small, precise mouth

You’re Probably Not Cleaning Your Dog’s Leash—But Here’s Why You Should Be

There are several items you use every day that you probably aren't cleaning enough, like your phone, your water bottle, and your pajamas. If you're a dog owner, there may be one especially filthy object in your home that you don't clean at all: your pet's leash. According to Reader's Digest, leashes get dirty fast, and if you can't remember the last time you cleaned yours, it's definitely due to be sanitized.

Leashes are just as easily soiled as anything you touch on a regular basis. Constant use causes microbes and oils from your hands to build up on the handle. And chances are, the leash is also covered with your dog's own germs, fur, and saliva, as well as mud and dirt from the outside world. This adds up to create a cocktail of nastiness on the leash that's hanging beside your front door.

The quickest way to gauge if your leash needs to be cleaned is to look at it. Is it covered with hair and splattered with mud? If yes, it should definitely be taken care of before your dog's next walk. But even a relatively neat looking leash should be cleaned about once a month. For rope and nylon leashes, let it soak in hot soapy water for 10 minutes before rinsing it and hanging it to dry. Scrubbing with a soft nylon brush may be necessary for tougher messes like stains and caked-on grime. Some leashes can also be safely cleaned in the washing machine in a delicates bag. If your dog's leash gets dirty quickly, you may want to invest in a few extras so you aren't constantly washing the one you have.

If you're looking for cleaning projects, disinfecting the items around your home that you've been neglecting is an excellent time-killer. From pillows to shower heads, here's how often you should be washing common household items.

Drive-Thru Coronavirus Testing Site in Pennsylvania Amish Country Accommodates Horses and Buggies

One way coronavirus testing centers can encourage social distancing is by testing patients in their vehicles. In Pennsylvania's Amish Country, that includes horses and buggies as well as cars. As CNN reports, a small clinic is accommodating the old-school transportation method in an effort to make tests more accessible to Amish and Mennonite communities.

Most residents of Belleville, Pennsylvania, are Amish or Mennonite—two groups that are uniquely vulnerable to the COVID-19 pandemic. Their cautious approach to technology can result in lower news consumption, which may leave people ill-informed about a crisis that's changing by the day.

Both communities are also tight-knit: a benefit in most times of hardship, but a recipe for tragedy during a pandemic. "When they have church, they have 300 people crowded together in a little farmhouse. From the point of view of an infection like this, this is a disaster," Dr. D. Holmes Morton, founder and medical director of the Central Pennsylvania Clinic in Belleville, told CNN.

Many Amish and Mennonite meetings and church services have been suspended indefinitely, but social distancing is just one part of keeping the communities safe. Testing is also essential to containing the virus, and the Central Pennsylvania Clinic aims to make its tests available to as many people as possible. As one of the few coronavirus testing sites in the area, they're working to test asymptotic patients as well as those who are feeling sick. Research suggests that up to 50 percent of novel coronavirus carriers show no symptoms.

The clinic is not just accommodating Amish and Mennonite patients, but also how they see them. Residents are able to roll up in their horses and buggies and get tested without stepping into the clinic. At least 65 people have used the drive-through (or ride-through) clinic since it opened on April 1.
