🌅🌪️ This dreamy-yet-haunting image from the spring of 1981 shows a tornado touching down near Cordell, Oklahoma. If you look closely, you can see a dust and debris cloud forming at the base of the twister. This shot is a product of the “Sound Chase” project, a collaboration between the U.S. National Oceanic and Atmospheric Administration’s National Severe Storms Laboratory and Mississippi State University.

This flashy fellow is a male peacock spider (genus: Maratus). These vibrant arachnids are famous for the colorful and iridescent markings on the abdomens of males used in courtship. Not only are these creatures visually striking, but they also have impressive dance moves. 💃 To seduce a mate, male Maratus spiders display their markings by raising their backend, all while performing a complex courtship dance complete with visual cues, vibrations, and even some percussive drumming. Maratus courtship rituals are not all fun and games, though: if a male’s performance fails to impress a potential mate, he may become her next meal. 🍴 Talk about a high-stakes performance! Tag a friend with moves!

The Mississippi River Delta has been an area of intense study for, among other things, the dynamic growth and loss of land experienced in the region due to natural and man-made causes. Although coastal wetlands are typically the topic of conversation, a recent paper published in the journal Geophysical Research Letters (Ortiz, Roy, & Edmonds, 2017) explores how pond expansion due to wind contributes to land loss, an inland erosion process referred to as ‘internal fragmentation.’ The scientists analyzed about 10,000 satellite images taken between 1982 and 2016 by the Landsat 8 satellite (a collaboration between the U.S. Geological Survey and NASA launched in 2013), and found that ponds in the area tend to grow in the direction of the prevailing winds. Their research led them to suggest that ponds in the Terrebonne and Barataria basins are unstable, where 80 percent of ponds are expanding. This image shows the area of study along the Atchafalaya Delta of Louisiana, which the authors deemed stable due to the fact that there are nearly as many ponds contracting as expanding.

The formidable Black Canyon of the Gunnison River is an awe-inspiring canyon in the American West most famous for its dramatic depth, extremely steep cliffs, narrowness, and unforgiving darkness. Located in western Colorado and millions of years in the making, the Black Canyon stretches for 77 kilometers (48 miles), with the deepest (and arguably the most spectacular) 22.5-kilometer (14-mile) section making up Black Canyon of the Gunnison National Park. The canyon reaches a maximum depth of 829.7 meters (2,722 feet) at Warner Point (accessible from the south), making it almost exactly as deep as the tallest free-standing structure in the world, the Burj Khalifa in Dubai, which is about 828 meters (2,716.5 feet) in height. The canyon is also very narrow, reaching a width of 12 meters (40 feet) at a section called ‘The Narrows.’ The Black Canyon gets its name from the fact that its severe steepness prevents much sunlight from piercing its depths, blanketing much of the canyon in shadow. In fact, author Duane Vandenbusche reports that sections of the Black Canyon only see 33 minutes of sunlight a day! What’s your favorite local canyon?

​This colorful parrot is a rainbow lorikeet, and is commonly found along the eastern seaboard of Australia. These medium-sized parrots are famous for the vibrant and striking plumage that is common to both males and females. While beautiful, these birds are not loved by all. There has been a few separate instances of rainbow lorikeets being accidentally or illegally released into non-native locations, such as Western Australia and New Zealand, resulting in non-indigenous, feral populations of the parrot being established. In Western Australia, rainbow lorikeets compete with indigenous bird species for food and nesting spots, and have adversely affected a number of native bird species. Additionally, the parrots are known to strip orchards of fresh fruit (much to the annoyance of farmers), and the birds are a nuisance in urban locations. This has led to the rainbow lorikeet being classified as a pest and an introduced species in some areas. In this photograph, we see two rainbow lorikeets on a flowering Xanthorrhoea in Western Australia. Do you know of any invasive species in your region? Let us know!

This is a blue whale. These marine mammals are the largest animals on Earth, and are even larger than almost all known dinosaurs. As growing calves, blue whales gain weight quickly, as much as 90 kilograms (198 lb) every day. 😮 As mature adults, they then reach a length of up to about 30 meters (98 ft), and a weight of up to around 181 metric tons (~400,000 lb)!

Wildlife photographer Giovanni Mari was exploring Andasibe-Mantadia National Park in eastern Madagascar when he came across this magnificent Parson’s chameleon about to capture its prey. 👅🐛 Chameleons primarily hunt insects, and use their unique tongues to strike from a distance. The chameleon tongue structure is composed mostly of tongue muscles, hyoid bones, and collagenous elements (structural proteins). The apparatus is able to reach an impressively long distance with some chameleons projecting their tongues more than twice their body length. Not only do they strike far, but also very fast: chameleons can reach their prey in 0.07 seconds. Tag a lizard fan!

Did you know that scorpions have a secret glow? 💡 We don’t entirely know why yet, but scorpions are fluorescent under ultraviolet light. The predatory arachnids are known to give off a blue-green glow when exposed to specific wavelengths of ultraviolet light, which is why a portable UV lamp has been a favorite tool for researchers studying these nocturnal creatures. What we do know is that all scorpions have fluorescent substances in a thin layer of their exoskeleton known as the epicuticle, and researchers have identified one of the fluorescent components in some species as beta-carboline (a tryptophan derivative). What we don’t know is what purpose this fluorescence provides. Any ideas? 🔬 Photo: Arnoud Quanjer. #guffscience #science #nature #biology #biochemistry #earth #education #bestoftheday #interesting #didyouknow #nowyouknow #naturelovers #natureshots #nature_perfection #animal #awesomeanimals #wildanimals #wildlife #arnoudquanjer #naturephotography #ultraviolet #blacklight #scorpion #fluorescence

This colorful creature is the peacock mantis shrimp of the Indo-Pacific, and the red mass below her is a carefully guarded collection of fertilized eggs. Females will continue to carry around their eggs until they hatch, continuously maintaining and cleaning them with their front appendages. They are unable to eat during this period because their front appendages are usually used for hunting. Aside from their visual beauty, peacock mantis shrimp are also famous for the strength of these front appendages. The shrimp use their front appendages and an extremely fast punching motion to break open and kill snails, mollusks, and other crustaceans. This punching motion is one of the fastest in the entire animal kingdom, and has been known to break through glass aquariums!

Are these Japanese macaques posing for a family photo? 📸🐒 Perhaps, but it’s more likely that these inhabitants of Shōdoshima Island are huddling together to pool body heat. Of the twenty-two different macaque species, all rely on complex relationships and societies to survive. These monkeys live in matrilineal social groups that sometimes have strict hierarchies and social customs. Somewhat similar to humans, Japanese macaques are famous for their group visits to the warm waters of relaxing hot springs! What’s your favorite kind of monkey?
