#6 Baffling Beetles
These insects seem to suffer from a case of identity crisis. They’re beetles that are native to Costa Rica and are very small at about 1.6 mm long. But they don’t look like beetles, nor do they live like them. This species lives within a colony of nomadic army ants and has kind of adopted their appearance. They’ve also adopted the ants as their means of personal transportation whenever the colony moves. The small, spindly beetles are known to latch onto the waist of worker ants, and let those insects carry them to their destination. Once it’s attached, the beetle mimics the appearance of the ant’s abdomen, making it look like the worker has two of those segments. Until they can get Uber, it looks like hitchhiking is the beetles best chance for a lift.
#5 Mariana Snailfish
These deep sea creatures belong to a family of fish that contains over 400 species. And geographically, they’re the world’s most widespread marine fish organisms. Members of this species measure about 29 centimeters long (11 inches) and appear like pale tadpoles. Although they weigh a scant 160 grams (0.35 pounds), they’re the top predators in their deep sea environment That includes various regions of the Mariana Trench, where depths can approach 8,500 meters (27,000 feet). Did you know that these snailfish inhabit the Challenger Deep? It’s located in the southern part of the Mariana Trench and contains the deepest point known in the planet’s seabed at nearly 11,000 meters (36,000 feet).
#4 Extremely Senior Citizens
Fossil specimens known as Dickinsonia (dik-in-so-nee-uh) were initially found in South Australia, and have since turned up in Ukraine and Russia among other locations. Specimens can range more than 4.5 feet long (1.4 m) and have a thickness of only a few millimeters. The fossils have engendered a lot of debate as to whether they were created by organisms like plants, fungi (fun-jie), or bacteria. Researchers have now concluded that the fossils belonged to animals, and not to something like an enormous amoeba. That’s because analysis revealed the presence of molecular fossils of cholesterol, which is only found in animals. Since they date back to the Ediacaran (ee-dee-AK-ur-uhn) period some 557 million years ago, Dickinsonia represents the world’s oldest known animal fossils! As for what type of animal created those fossils is still open to debate. Tell us what you think in the comments.
#3 Frogs with Fangs
Now there’s a phrase you don’t hear so often. But these amphibians endemic to Indonesia are indeed known to possess such choppers. The animals are around 1.5 inches long (37 mm) from snout to vent and are known for having well-developed tails and mouth parts at birth. As to the purpose of those fangs? Experts say that many amphibians have teeth, although they’re very different from ours. The fangs of these frogs aren’t really teeth, though. They’re bony protrusions that erupt through the gumline. The spike-like structures might be used for snatching prey from fast-moving water. But their exact function still remains a mystery. Have any ideas?
#2 Deepsea Lizardfish
This unusual beast was initially found in 2017 off the eastern coast of Australia and was then declared a distinct species about a year later. They have slender cylindrical bodies that can reach more than 70 cm long, and huge mouths filled with sharp, needle-like teeth used to capture and tear at prey. Researchers say they’re one of the world’s deepest dwelling apex predators. And they’re known to eat anything, including others of their kind. But they’re not worried about ravaging their population. These creatures are hermaphrodites that possess both male and female reproductive traits. Living some 3,500 meters (11.500 feet) below the surface, these lizardfish don’t get to hook up so often. As hermaphrodites, they can perpetuate the species regardless of which gender they encounter.
This site provides links to random videos hosted at YouTube, with the emphasis on random.
The original idea for this site actually stemmed from another idea to provide a way of benchmarking the popularity of a video against the general population of YouTube videos. There are probably sites that do this by now, but there wasn’t when we started out. Anyway, in order to figure out how popular any one video is, you need a pretty large sample of videos to rank it against. The challenge is that the sample needs to be very random in order to properly rank a video and YouTube doesn’t appear to provide a way to obtain large numbers of random video IDs.
Even if you search on YouTube for a random string, the set of results that will be returned will still be based on popularity, so if you’re using this approach to build up your sample, you’re already in trouble. It turns out there is a multitude of ways in which the YouTube search function makes it very difficult to retrieve truly random results.
So how can we provide truly random links to YouTube videos? It turns out that the YouTube programming interface (API) provides additional functions that allow the discovery of videos which, with the right approach, are much more random. Using a number of tricks, combined some subtle manipulation of the space-time fabric, we have managed to create a process that yields something very close to 100% random links to YouTube videos.
YouTube is an American video-sharing website headquartered in San Bruno, California. YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
YouTube and selected creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google. As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.
YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos, its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods, hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters, videos of minors attracting pedophilic activities in their comment sections, and fluctuating policies on the types of content that is eligible to be monetized with advertising.
