Originally, Aristotle separated all living things into two categories: plants and animals. Plants move too slowly for people to notice. These became the kingdoms Vegetabilia (later Plantae) and Animalia in Linnaeus’ system. Since then, it has been evident that the Plantae as originally classified includes multiple unrelated taxa, and fungi and some algal groups have been reassigned to different kingdoms. However, in many circumstances, these are still considered plants. Bacterial life is occasionally included in flora, and some classifications distinguish between plant and bacterial flora.
Regional floras, which can also include fossil flora, relics of plant life from a prior epoch, depending on the objective of study, are one of the various ways to classify plants. People in many regions and countries take great interest in their unique collections of flora, which can vary greatly throughout the globe due to climate and topography variances.
Native flora, agricultural and garden flora, and purposely developed and cultivated flora are some of the most popular classifications used to categorize regional floras. Some “native flora” was really imported centuries ago by people migrating from one region or continent to another, and has since formed an integral part of the native, or natural flora of the new location. This is an example of how human involvement with nature can cause the definition of what constitutes nature to be questioned.
Weeds have traditionally been assigned to a different plant category. Though the term “weeds” has gone out of favor among botanists as a formal manner of classifying “useless” plants, the informal use of the phrase to designate plants that are regarded worthy of eradication exemplifies people’s and cultures’ overall desire to influence or shape the path of nature. Similarly, animals are frequently classified as domestic, farm animals, wild animals, pests, and other terms based on their interaction with humans.
Animals as a group share a number of qualities that distinguish them from other living creatures. Animals, unlike bacteria, archaea, and most protists, are eukaryotic and usually multicellular (but see Myxozoa). They are heterotrophic, digesting their food in an interior chamber that keeps them away from plants and algae. They also differ from plants, algae, and fungi because they lack cell walls.
Animals, with a few exceptions—most notably the two phyla of sponges and placozoans—have divided bodies into tissues. Muscles, which may contract and control locomotion, and the nervous system, which transmits and interprets information, are among them. There is usually an internal digestive chamber as well. All animals have eukaryotic cells that are surrounded by an extracellular matrix made up of collagen and elastic glycoproteins. This can be calcified to form shells, bones, and spicules, which provide a framework for cells to move around and reorganize during growth and maturation, as well as supporting the complex anatomy required for mobility.

How and why mountain goats climb so high?
Mountain goats, like Ibex and baboons, are among the most renowned animal climbers. The mountain goat’s keen eyesight allows it to plan the most effective ascent route. The bodies of mountain goats are quite thin. This improves their aerial balance by allowing them to move across ledges and stay closer to rocks. The mountain goat’s hooves are made up of two spreadable parts. The mountain goat can grab a bigger surface area when stretched out, which gives it a stronger grip. Also tough are the hooves. They have soft pads that conform to the curvature of the peak the goat ascends. A “speed breaker” in the form of two dewclaws is also provided to the mountain goat to slow down its descent. The back of its legs are covered in dewclaws.
When their parents lead them uphill, kids likewise fall. Within 48 hours of birth, a child can usually go climbing with its mother. It would sometimes shield its kid from such misfortunes by strategically positioning herself beneath her child as they ascended. This way, parent can use her legs to break the kid’s falls when it tumbles, or she can nudge the kid before it takes a disastrous step on their ascent. Mountain goats frequently travel great distances in quest of food. They could simply be grazing and climbing higher and higher, almost instinctively, in search of more grass. Mountain goats would similarly climb high to avoid being eaten by predators. A mountain goat can take its young to incredible heights simply to protect them from carnivorous predators.
Sanderling / Calidris alba
The sanderling is a little, whitish sandpiper with black legs and a black bill that is straight. Sanderlings have a compact, robust body that measures seven to eight inches long and has a 14-inch wingspan. In the spring, their plumage is brownish-gray, while in the winter, it is grayish-white. Their wings have a broad white stripe bordered by black and a white belly. They have a black bill that is straight and black legs. Bristle worms, amphipods, mollusks, and crustaceans are among the small, beach-dwelling creatures eaten by this bird. It eats by probing the sand with its bill along the water’s edge. Small flocks scurry along the water’s edge, fleeing approaching waves fast.
Annual Halloween Celebration at Oregon Zoo
The annual Squishing of the Squash at the Oregon Zoo features an Asian elephant family. During the Oregon Zoo’s 23rd annual Squishing of the Squash, some of the world’s largest land animals crushed some of the area’s largest pumpkins.The Oregon Zoo’s Asian elephant program, which has lasted more than 60 years, is well-known around the world. Asian elephants are considered highly endangered in their range countries due to habitat degradation, human conflict, and disease. Only 40,000 to 50,000 elephants are thought to persist in dispersed groups from India to Borneo. The zoo supports a variety of initiatives to protect wild elephants, including a $1 million endowment fund dedicated to Asian elephant conservation.
