Squids, octopuses, and cuttlefishes are among the few animals in the world that can change the color of their skin in the blink of an eye. These cephalopods—a group of mollusks with arms attached to their heads—can change their skin tone to match their surroundings, rendering them nearly invisible, or alternatively give themselves a pattern that makes them stand out. Many thousands of color-changing cells called chromatophores just below the surface of the skin are responsible for these remarkable transformations. The center of each chromatophore contains an elastic sac full of pigment, rather like a tiny balloon, which may be colored black, brown, orange, red or yellow. If you squeezed a dye-filled balloon, the color would be pushed to the top, stretching out the surface and making the color appear brighter—and this is the same way chromatophores work. A complex array of nerves and muscles controls whether the sac is expanded or contracted and, when the sac expands, the color is more visible. Besides chromatophores, some cephalopods also have iridophores and leucophores. Iridophores have stacks of reflecting plates that create iridescent greens, blues, silvers and golds, while leucophores mirror back the colors of the environment, making the animal less conspicuous. The most obvious reason such a soft-bodied animal would change color is to hide from predators—and octopuses are very good at this. They can change not only their coloring, but also the texture of their skin to match rocks, corals and other items nearby. They do this by controlling the size of projections on their skin (called papillae), creating textures ranging from small bumps to tall spikes. The result is a disguise that makes them nearly invisible; can you even see the octopus in the video above? Color changing is just one tool in an octopus’s arsenal of defenses, however; it can also spray ink, and make a quick escape through any hole it can get its hidden bony beak through. The Mimic Octopus (Thaumoctopus mimicus) has a unique way of camouflaging. Rather than blending in with the seafloor, it changes its skin color and how it moves its tentacles to take on the shape of other sea creatures. It has been known to impersonate more than 15 different marine species, including flounders, lionfish, and sea snakes. Octopuses and cuttlefish also use color change to warn their predators or any animals that threaten them. One of the best examples is the extremely venomous blue-ringed octopus (Hapalochlaena lunulata), which lives in tide pools in the Pacific and Indian Oceans from Japan to Australia. When these small octopuses are provoked, iridescent blue rings surrounding dark brown patches appear all over their bodies. Despite its beauty, this reaction means, “If you touch me you will most likely get hurt!” Cephalopods can also use chromatophores to communicate with one another. Male Caribbean reef squid (Sepioteuthis sepioidea) turn red to attract females and white to repel other males—and can even split the coloration of their bodies down the middle to attract a female on one side and repel a male on the other! The Humboldt Squid (Dosidicus gigas), also called the “Jumbo Squid” and the “Red Devil,” is known for its flashing colors. This flashing is suspected to be a means of communication—but no one knows what the squid are trying to say. No wonder cephalopods are sometimes called chameleons of the sea!

Watch this fun video of these amazing border collies running in the wild! -- The Border Collie is a working and herding dog breed developed in the Anglo-Scottish border region for herding livestock, especially sheep. It was specifically bred for intelligence and obedience. Considered highly intelligent, extremely energetic, acrobatic and athletic, they frequently compete with great success in sheepdog trials and dog sports. They are often cited as the most intelligent of all domestic dogs. Border Collies continue to be employed in their traditional work of herding livestock throughout the world. -- In general, Border Collies are medium-sized dogs with a moderate amount of coat, which is most often thick and sheds often. They have a double coat that varies from smooth to rough and is occasionally curled. While black and white is the most commonly seen colour pattern of the Border Collie, the breed appears in just about any colour and pattern known to occur in dogs. Some of these include black tricolour (black/tan/white), liver and white, and red tricolour (red/tan/white) which have also been seen regularly, and other colours such as blue, lilac, red merle, blue merle, brindle, and Australian red (also known as ee red, blonde, recessive red, or gold) which is seen less frequently. Some Border Collies may also have single-colour coats. Eye colour varies from brown to blue, and occasionally eyes of differing colour occur; this is usually seen with merles. The ears of the Border Collie are also variable — some have fully erect ears, some fully dropped ears, and others semi-erect ears (similar to those of the rough Collie). Although working Border Collie handlers sometimes have superstitions about the appearance of their dogs (handlers may avoid mostly white dogs due to the unfounded idea that sheep will not respect a white or almost all white dog), in general, the American Border Collie Association considers a dog's appearance to be irrelevant. Instead, it is considered more useful to identify a working Border Collie by its attitude and ability. Dogs bred for show are more homogeneous in appearance than working Border Collies, since to win in conformation showing they must conform closely to breed club standards that are specific on many points of the structure, coat, and colour. Kennel clubs specify, for example, that the Border Collie must have a "keen and intelligent" expression, and that the preferred eye colour is dark brown. In deference to the dog's working origin, scars and broken teeth received in the line of duty are not to be counted against a Border Collie in the show ring. The males' height from withers comes from 48 to 56 centimetres (19 to 22 in), females from 46 to 53 centimetres (18 to 21 in).

I was walking in Hyde Park and suddenly found this hungry little fella on the way. -- Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels, chipmunks, marmots (including woodchucks), flying squirrels, and prairie dogs amongst other rodents. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known squirrels date from the Eocene period and are most closely related to the mountain beaver and to the dormouse among other living rodent families. -- That word "squirrel", first attested in 1327, comes from the Anglo-Norman esquirel which is from the Old French escurel, the reflex of a Latin word sciurus. This Latin word was borrowed from the Ancient Greek word σκίουρος, skiouros, which means shadow-tailed, referring to the bushy appendage possessed by many of its members.[2][3] The native Old English word for the squirrel, ācweorna, survived only into Middle English (as aquerne) before being replaced. The Old English word is of Common Germanic origin, cognates of which are still used in other Germanic languages, including the German Eichhörnchen (diminutive of Eichhorn, which is not as frequently used), the Norwegian ikorn/ekorn, the Dutch eekhoorn, the Swedish ekorre and the Danish egern. -- Squirrels are generally small animals, ranging in size from the African pygmy squirrel at 7–10 cm (2.8–3.9 in) in length and just 10 g (0.35 oz) in weight, to the Laotian giant flying squirrel at 1.08 m (3 ft 7 in) in length and the Alpine marmot, which weighs from 5 to 8 kg (11 to 18 lb). Squirrels typically have slender bodies with bushy tails and large eyes. In general, their fur is soft and silky, though much thicker in some species than others. The coat color of squirrels is highly variable between—and often even within—species.

I was diving and suddenly bumped into this lovely sea turtle eating. It was so cute that I couldn't not film it - plus, it was an awesome experience! Sea turtles (superfamily Chelonioidea), sometimes called marine turtles, are reptiles of the order Testudines and of the suborder cryptodira. The seven existing species of sea turtles are: the green, loggerhead, Kemp's ridley, olive ridley, hawksbill, flatback, and leatherback. -- he majority of a sea turtle's body is protected by its shell. The turtle's shell is divided into two sections: the carapace (the dorsal portion) and the plastron (the ventral portion). The shell is made up of smaller plates called scutes. The leatherback is the only sea turtle that does not have a hard shell. Instead, it bears a mosaic of bony plates beneath its leathery skin. In general, sea turtles have a more fusiform body plan than their terrestrial or freshwater counterparts. The reduced volume of a fusiform (tapering at both ends) body means sea turtles cannot retract their head, legs, and arms into their shells for protection like other turtles can. However this more stream-lined body plan reduces drag in the water and allows the turtle to swim more easily. The leatherback is the largest species of sea turtle. Measuring 2–3 meters (6–9 ft) in length, and 1-1.5 m (3–5 ft) in width, weighing up to 700 kilograms (1500 lb). Other species are smaller, being mostly 60–120 cm (2–4 ft) and proportionally narrower. -- Sea turtles, along with other turtles and tortoises, are part of the order Testudines. All species except the leatherback are in the family Cheloniidae. The leatherback is the only extant member of the family Dermochelyidae. The origin of sea turtles goes back to the Late Jurassic (150 million years ago) with genera such as Plesiochelys, from Europe. In Africa, the first marine turtle is Angolachelys, from the Turonian of Angola. However, neither of these are related to extant sea turtles; the oldest representative of the lineage leading to these was Desmatochelys padillai , from the Early Cretaceous. A lineage of unrelated marine testudines, the pleurodire (side-necked) bothremydids, also survived well into the Cenozoic. Other pleurodires are also thought to have lived at sea, such as Araripemys.[8] Sea turtles constitute a single radiation that became distinct from all other turtles at least 110 million years ago. Sea turtles' limbs and brains have evolved to adapt to their diets. One of the main things sea turtles consume is jellyfish and the use of their limbs to hold, swipe, and forage their food has helped them eat more efficiently. Originally sea turtles' limbs have evolved for locomotion but now they have evolved to aid them in the ability to get food. In addition to the evolution of limbs, sea turtles' brains have also evolved. The frontal cortex of a sea turtle's brain was not very developed. This underdevelopment caused the sea turtles to not be able to learn from their surroundings.

The Golden Bridge is a 150-metre long pedestrian bridge in the Bà Nà Hills resort, near Da Nang, Vietnam. It is designed to connect the cable car station with the gardens (avoiding a steep incline and to provide a scenic overlook and tourist attraction. The bridge loops nearly back around to itself, and has two giant stone hands designed to appear to support the structure. The client for the project was the Sun Group. The bridge was designed by TA Landscape Architecture based in Ho Chi Minh City. The company's founder, Vu Viet Anh, was the principal designer. The bridge opened in June 2018.

Check out this phenomenal cover of Ed Sheeran's “Shape Of You” by an incredibly talented female artist. You are sure to enjoy her melodious voice that transcends her audience into a state of calmness, tranquility, and warmth. Ed Sheeran is an incredible artist who has become immensely popular and well-known. This particular song of Sheeran is actually more popular than many people realize. For example, YouTube has stated that the song “Shape of You” is “the second-most viewed YouTube video by views.” It is mind blowing when fans realize that the song has achieved 3.88 billion views! That is absolutely incredible. This is not an easily acquired task, and it is definitely a huge success that very few people on the entire planet can say they have reached. This just does not happen every day. This is one of the few examples of an artist who could literally live the rest of their lives off of the profits from just one song, and they would never have to worry about any kind of work ever again if they did not want to. This is every person’s dream, but few get to reap these kinds of benefits. The artist who is featured in this video has a very unique voice and her singing brings some novelty and freshness on the Internet. There is no denying that she is greatly gifted and talented musically. With her <a href="https://rumble.com/v6ewu9-hallelujah-violin-cover-by-karolina-protsenko.html" target="_blank">performance</a> she will definitely stay in the memory of people watching her. The singer is obviously on her way up the ladder, but she is going to have to continue to keep on working hard to get herself really famous. This is especially true in today’s <a href="https://rumble.com/v4ielt-how-frank-ocean-trolled-the-music-industry.html" target="_blank">music industry</a>. The entire picture of show business is totally different from the way things used to be. It is now much more difficult to get discovered and to get your music out to the public. We do not have to know many details of this woman’s life to be able to see that she is obviously pursuing a music career, and she has the potential to really be and do something great. She has a soft voice that is very relaxing and melodious for sure. However, to become a mega celebrity, she may have to find that piece of her music and rhythms that make her stand out from the rest. One of the reasons that it is going to be more difficult for this young woman to make a name for herself in this incredibly brutal industry is partly attributed to the fact that most people nowadays do not buy CD’s and albums. People all around the world can now just go to a website online and have everything available at a fingertip. No matter what this young woman encounters, though, she seems to have the heart and drive to do the work that it will take her to wherever it is that she wants to be. We send our good wishes of luck as she endeavors to fulfill her dreams of being a singer and a performer!

Check out this fantastic cover of Tracy Chapman's “Fast Car” by this exceptional artist. This song was written in 1988. Tracy Chapman was an incredible artist that people still love to this day. What a talent! “Fast Car” was one of her most popular songs, alongside “One Reason,” which is arguably her best and most popular song above all of the others. Her <a href="https://rumble.com/v4hbw9-all-the-stars-feat.-sza-cover-with-scissors-kendrick-lamar.html" target="_blank">songs are often covered</a> by artists such as the one in this video, and they are always extremely popular in karaoke performances for sure! Chapman’s album that “Fast Car” appeared on was a self-titled album, “Tracy Chapman.” The performance that really put her on the map was when she appeared and performed for Nelson Mandela’s seventieth birthday. After this performance, her song became a mega hit. It ended up earning this amazing performer two nominations for the coveted Grammy Award. She was nominated for “Record of the Year” and “Song of the Year.” This is an incredible accomplishment. The next year in 1989, she was nominated for even more awards, including the “Video Music Award” and “Best Female Video.” Chapman had a very unique sound to her vocals that was very new and fresh in her time. She was different, and that is what made her so memorable. The artist in this video could certainly one day follow in Tracy Chapman’s footsteps being as <a href="https://rumble.com/v50x67-professor-and-her-students-cover-halo-by-beyonce-a-capella.html" target="_blank">talented</a> as she is. It is truly a beautiful performance, and there is no doubt that her audience feels the same way. While we may not know any details about this woman’s personal life, we hope that she is pursuing a career in music. She has a soft voice that is very relaxed and melodious for sure. She does not have the uniqueness that Chapman has in her voice, but there is certainly something special there. However, to become a mega celebrity and to be as successful as Chapman, she may have to find that piece of her music and vocals that makes her stand out from the rest. Today’s music industry is not what it used to be. It is much more difficult nowadays to become a well known and super successful artist. This is partly attributed to the fact that most people do not still purchase CD’s and albums in that nature. Instead, streaming has become the new “in thing.” When you can go to YouTube and see and listen to the exact song that you want to listen to without having to actually pay for it, why wouldn’t you? Of course you would. However, that is what is creating such an enormous problem for the artists in the music industry. This creates an especially difficult and large obstacle to young artists and new artists who are trying to break into the business. The woman in this video may be encountering the same difficulties if she is trying to start or maintain a career in the music industry. Whatever the case may be, it is evident that this woman does have a natural talent, and we wish her all the luck in the world to be successful!
