The young penguins of South Africa shed their down, preparing for the struggle to come. Since their habitat was destroyed by mining, eggs are laid on sand instead of burrows, and the exposure to the elements kills many eggs before they hatch. Parents are forced to venture many more kilometers out to sea to find fish, as trawlers empty the ocean for distant tables. Regulations limiting fish harvests is desperately needed, not only for sea birds but for people who traditionally make their living fishing off the coast. In international waters, trawlers have total freedom, which can collapse fisheries. Alternatively, reducing ocean fish in your diet can counter this problem.
Mostly due to habitat loss, brown hyenas are the rarest of the hyena species, with 4-10 thousand individuals in the wild. There are 30-50 thousand wild spotted hyenas, for comparison.
Brown hyenas are also known as strandwolves, which means "beach wolves" in Afrikaans, a language spoken primarily in South Africa. This name was given to them because brown hyenas in coastal areas spend a lot of time walking down beaches in search of food, and maybe to unwind after a long day. Some of the largest brown hyena populations are found in these coastal areas of Southern Africa, but there are also large populations in the Kalahari desert.
Although the name strandwolf suggests it, brown hyenas are not closely related to wolves or other canines. They can resemble canines, but hyenas are more closely related to cats than dogs. Their closest relatives are mongooses and civets. The photo below shows an African civet.
Brown hyenas are generally smaller than striped and spotted hyenas, but they can still get pretty big, weighing up to 90 pounds (40.8 kg). This size and their powerful jaws make them seem like formidable predators, but they're pretty bad hunters. They mostly scavenge for food or steal it from more capable hunters like cheetahs, leopards, and jackals. Since they can digest bones, hooves, horns, hair, and skin, they can basically eat every scrap food they find. Brown hyenas often live in groups, but this scavenging is done on their own.
Their clans are much smaller than those of spotted hyenas, and the structure is more similar to a wolf pack; most hyenas in the group are the offspring of the dominant hyenas. Brown hyenas are very social and form close bonds with other hyenas.
I rate the brown hyena 17/10. I like them. They seem a little bit lazy with their poor hunting skills and walks down the beach

Vida's Sheep Jumping Spider: researchers believe that these tiny spiders developed their "woolly" appearance as a way to mimic lacewing larvae or scale insects
The scientific name for this species is Oviballus vidae, but it has also been referred to as the "sheepy jumping spider" or "Vida's jumping spider." It was discovered in 2015, and first described (in a formal context) back in 2020.
As this article (PDF) describes:
Recently, two new salticids, R. legitima and Oviballus vidae were described from South Africa, and suggested to be mimics of either scale insects (Hemiptera: Coccoidea) or lacewing larvae (Neuroptera: Chrysopidae), due to their white colouration and the presence of peculiar tufts of white setae on the body.
The possibility of [scale insects] being the model is supported by Oviballus vidae being regularly collected from plants with woolly scales, although the movements of O. vidae quite closely resemble those of chrysopid larvae.
In fact, a fourth species of possible scale mimic, a new Rhene species, was recently discovered in a collection of salticids
from southern Mozambique, indicating that this phenomenon may be more widespread than has previously been known or even suspected.
O. vidae was named after Vida van der Walt, the photographer who captured some of the first images of these spiders back in 2015, just after the species was discovered by Dr. Galina Azarkina. Vida van der Walt also took the photographs that appear in this post.

A mix of 160 Cape and African white-backed vultures to their new home at the Shamwari Private Game Reserve in Eastern Cape. Both rehabilitated vultures and purposely breed vultures.
The exclusive 54,300-acre reserve is patrolled by an anti-poaching team, and birds will be able to scavenge with little to no human exposure.
Vultures prevent harmful pathogens such as anthrax and brucellosis bacteria by destroying them in the vulture stomach.
