You may not be able to tell from this photo, but the white sturgeon is North America's largest fish. To date, the largest on record was caught in 1898 and weighed approximately 1,500 pounds! Vintage photographs reveal fish so large that, once caught, horses were needed to pull them from the water. In the late 1800s, commercial fisheries began to target this species to meet the demand for caviar (sturgeon eggs) and smoked sturgeon. These fisheries grew so rapidly that they collapsed towards the end of the 1800s due to over-fishing. The population began to rebound in the early 1900s when California banned commercial and sport fishing of white sturgeon. In recent years management of fisheries has also improved – environmentally safe farms now raise white sturgeon for fillets and caviar, helping to ensure populations in the wild remain.

Hi Everyone, I’d like to interrupt our ‘regularly-scheduled programming’ this summer to show you a few of the things we all can do to save the planet. In this case, the lesson literally starts in our own backyard! Knowing that butterflies, bees and other pollinators are in real trouble, we tilled up the grass in front and behind our office in order to plant Asclepias syriaca, or common milkweed - a species of milkweed native to our area that monarch caterpillars depend on. Click the link in my bio to find the right species of milkweed to grow in your area. Next up, we’ll plant nectar bearing plants and prairie grasses. Stay tuned!

Meet Billy – an Andean bear @parquejaimeduque. This species is often referred to as the spectacled bear because of the rings of light fur around the eyes, which look like a pair of glasses. Very little is known about them, however. In the wild they are very shy and tend to avoid humans. What we do know is that habitat loss is driving these bears out into the open, leading to human encounters. As their habitat shrinks, the bears stray onto farmland, feeding on the crops that replaced their natural diet, and the construction of new roads fragments bear habitat, increasing the risk of collisions with vehicles and poaching. In an effort to protect this gentle giant, Andean bears are now protected by international trade laws, and local people in bear habitats are being educated about the benefits of preserving habitat for the bears, tourism and the protection of water sources. #Nationalbearawarenessweek #gentlegiant #spectacledbear #andeanbear #billy #photoark #savetogether

Scarab beetles, like this emerald beetle from Kenya, play an important role as decomposers in many natural communities. Both the colorful, hard-coated adult beetles and their larvae feed on and break down plant matter. This action helps to create soil which contains all of the nutrients plants need to grow! To encourage beetles to visit your yard, try keeping a log or pile of dead wood present in your garden.

On this endangered species day, pledge to save Amur leopards like Usi @theomahazoo by avoiding animal-skin products. In the Russian Far East, agricultural plots and villages surround the forests where the leopards live, making poaching a problem not only for the leopards themselves, but also for important prey species, such as roe deer, sika deer and hare, which are hunted regularly. While deer and hare may be hunted as a source of food, the leopard is targeted for its beautiful, spotted fur. Saving this species ensures that the ecosystem remains balanced, which benefits both animals and humans. By acting as a smart consumer, you play a vital role in helping this species’ numbers recover. #endangeredspeciesday #amurleopard #leopard #russia #criticallyendangered #spotted #bigcat #carnivore #photoark #savetogether

This stunning bird is a lilac-breasted roller @theomahazoo. Ranging throughout eastern and southern Africa, this species is highly territorial, driving off any intruders that get too close to their nest. Because of this need for clearly defined boundaries, rollers choose to live in areas with trees that are spaced apart from one another and typically avoid areas inhabited by humans. This habitat is also ideal for hunting, as this bird has a knack for perching on a dead tree and snatching up prey fleeing from brush fires. After a successful hunt the roller will return to its perch and batter its prey to kill it before swallowing it whole. #roller #lilacbreastedroller #africa #territorial #colorful #photoark #savetogether

How did this gray four-eyed opossum get its name? It is the result of a unique adaptation that this nocturnal creature uses to fool potential predators! The opossum has white patches of fur above its eyes that give it the appearance of being awake, even when sleeping soundly. If this defense mechanism fails, the gray four-eyed opossum does not “play dead” like the Virginia opossum – instead, it is aggressive and ready for battle. A resident of Central and South America, this species does not have a well-defined territory, and home range stability depends on easy access to food and shelter. While adaptable and not currently in danger, this opossum, like many other species, is counting on us to adopt wildlife-friendly behaviors to secure their future for generations to come.

Gopher tortoises like this one @zooatl got their name because of their ability to dig large, deep burrows similar to gopher holes. These burrows aren’t just important shelter for the tortoises –they're often taken over by other species living in the same area, making gopher tortoises a key player in ensuring the survival of many other animals native to the southern U.S.. Unfortunately, collisions with vehicles are a major threat to these tortoises, as many individuals have to cross roadways in order to forage, find mates, or build a new home. If you live in a state that the gopher tortoise calls home check out the link in my bio to learn best practices and how you can report a sighting. #tortoise #gophertortoise #brakeforwildlife #vulnerablespecies #photoark #savetogether

​The figure in this image may look like a clump of moss, but upon closer inspection you’ll find that it is actually a pied mossy frog @houstonzoo! In their home country of Vietnam, this species will hide in basins of water with only its eyes protruding, allowing it to keep a close watch on its surroundings. This frog can also throw its voice up to 13 feet away - this in conjunction with its looks and overall demeanor makes finding this guy in the wild almost impossible. Having a well-rehearsed disappearing act is vital to the survival of this species as it is in high demand in the international pet trade. Remember to choose your pets wisely and do your research before bringing an animal home. Exotic species require a great deal of special care, and often their best chance for survival is in their natural habitat. #piedmossyfrog #frog #amphibian #mossy #notapet #vietnam #photoark #savetogether

Happy Mother’s Day from this white-bellied pangolin and her baby @pangolinconservation. The juvenile, called a pangopup, was only 70 days old when this photo was taken and was the first of her species to be bred in captivity in the U.S.. Pangopups rely on their mother’s milk for the first several months of life and will catch a ride on mom’s tail whenever possible. With a strong maternal instinct, pangolin moms will ball themselves up around their baby when danger is near to shield it from any potential threats. While all eight species of pangolin are in danger of extinction due to illegal trafficking, there is reason for hope. The @PangolinSG is working hard to combat the trafficking crisis and raise awareness among governments and NGOs. You can support this species by using the power of your network to bring attention to this incredible creature. #mothersday #pangolin #pangopup #scalyanteater #dragonscales #baby #love #photoark #savetogether

Commonly known as a bearcat, the binturong looks a bit like a cartoon drawing with the face of a cat, the body of a bear, and a tail as long as its body. This species proves that looks can be deceiving, as it isn’t related to bears or cats! Instead, binturongs are related to civets and fossas. They are one of only two carnivorous species with a prehensile tail (meaning it can grasp and hold onto objects), and despite their classification as a carnivore, this species prefers to eat fruit! Their diet makes them a key player in re-planting the rainforest, as their fecal deposits spread seeds from the fruits they eat all across their home range.

Its national shrimp day! In celebration, let’s take a look at a species that is often overlooked – the camel shrimp @aquariumdenver. This species goes by many names thanks to several unique characteristics. ​The name camel shrimp comes from the hump formed by its abdomen, but it is also known as the candy shrimp because of its striking red and white coloration, and the dancing shrimp because of its movements. As the ultimate night owl, this shrimp was believed to be extremely rare until people started diving at night. The camel shrimp wasn’t rare at all – it was nocturnal! In the wild, this species communes within well-developed caves in the tropics, often accompanied by black-spined sea urchins. #nationalshrimpday #camelshrimp #candyshrimp #dancingshrimp #nocturnal #photoark #savetogether
