They’re known as “charismatic megafauna” for a reason. These endangered animals ooze star power, a factor that conservationists have capitalized on in order to fund projects to protect them (and, often by default, the other organisms that share their complex ecosystems). People are far more likely to donate money to save an adorable panda or a magnificent tiger than they are to drop some shekels on preserving the limbless worm skink or the Gerlach’s cockroach. However, skinks and roaches are integral participants in their ecosystems as well and just as deserving of assistance as their flashier compatriots. You might then consider the animals on this list the A-listers whose box office draw finances the continued existence of the lesser-known character actors who inhabit the same environments. And if the concept of trickle-down conservation sticks in your craw, get to work on that “save the Gerlach’s cockroach” Kickstarter campaign. I’d donate. Maybe.
1.Orangutan (Pongo pygmaeus)
“Orangutan” is Malaysian for “person of the forest.” Though morphologically they may resemble melted Muppets more than people, their sophisticated cognitive abilities are very human indeed. Like gorillas and chimpanzees, they have been known to use tools. Due in large part to logging and capture for the exotic pet trade, orangutans—restricted to the Southeast Asian islands of Borneo and Sumatra—number fewer than 60,000 per a 2004 study. Unlike other great apes, they are usually solitary or live in groups of fewer than three, making them difficult to track and study.
2.Tasmanian devil (Sarcophilus harrisii)
Between 1996 and 2008, the population of Tasmanian devils dropped some 60% due a contagious cancer known as Devil Facial Tumour Disease. It continues to decimate populations of the species, which only occurs on the Australian island of Tasmania. There may only be 10,000 wild individuals remaining. Captive breeding of uninfected individuals has been instituted and efforts have been made to develop a vaccine for the cancer, which is thought to have stemmed from mutated cells from a single specimen.
3.Gorilla (Gorilla beringei andGorilla gorilla)

4.Snow leopard (Panthera uncia)

5.Sea otter (Enhydra lutris)

6.Asian elephant (Elephas maximus)
7.Blue whale (Balaenoptera musculus)

8.Whooping crane (Grus americana)
In 1938, the first year a population survey was conducted, only 29 whooping cranes remained in the wild. Three years later, only 16 were left. Hunting and reduction of their wetland habitat had vitiated the population and concerted efforts to salvage remnant birds did not being until the late 1960s. Today, there are over 400 birds, thanks in large part to innovative breeding programs. Though a plan that involved transferring whooping crane eggs to the nests of related sandhill cranes for fostering ultimately failed, captive rearing and reintroduction have established two wild populations in Florida, one of which has been taught to migrate to Wisconsin. Neither is self-sustaining. The only self-sustaining population migrates between Alberta, Canada, and Texas, U.S.
9.Tiger (Panthera tigris)
William Blake’s “forests of the night,” the stalking grounds of the six subspecies of tiger, are burning bright. Slash-and-burn agriculture, along with logging, and human encroachment, have hugely diminished the habitat available to these felines, which require extensive ranges capable of supporting the large herbivores that constitute the bulk of their diets. Poaching—for trophies and body parts used in Asian “medicine” —is thought to pose the greatest threat to tigers. Probably fewer than 4,000 are left in the wild. In 2014, China explicitly outlawed the consumption of endangered species, including tigers, whose bones, penises, and other organs are superstitiously believed to have magical curative powers.
10.Giant panda (Ailuropoda melanoleuca)
Everyone loves a panda…they might be the kitschiest animal humanity has driven to the brink of extinction yet. From stuffed animals to martial arts-trained CGI abominations, we just can’t seem to get enough of the bi-colored beasts. Though their “aww factor” may verge on the cloying, it hasn’t been without effect. China, which is home to the remaining wild population of fewer than 2,500 individuals, has since the late 1980s instituted more stringent habitat protections and poaching has all but ceased. Their status is still tenuous, though. Their range is fragmented and they are still subject to disease, occasional predation, and starvation when large swathes of the bamboo on which they feed completes its life cycle and dies.
