We have more mammoths than dodos

It makes sense when you think of population size and location (lots of mammoths stuck in permafrost, not so many dodos on a tropical island) but it still feels weird that we have more preserved remains* of something that (largely) died out over 10,000 years ago than we do of something that died out <400 years ago. I guess there are plenty of things that have died out in my lifetime that we have few samples of. * As in preserved soft tissues rather than skeletons


Tiger Tiger

Great news from India:

India says it now has almost a third more tigers than it did four years ago.

Presenting the findings of the latest tiger census, Environment Minister Prakash Javadekar said the tiger population had risen from 1,706 in 2011 to 2,226 in 2014.

Last year I watched the documentary that follows the Head of Tigers (probably not his actual title) at Australia Zoo (the Sumatran tigers there are amazing) and part of it showed him travelling to Indonesia to see the guys fighting tiger poaching; it was pretty upsetting stuff. We have to try harder to conserve and protect.



An endling is an individual that is the last of its species or subspecies. Once the endling dies, the species becomes extinct

I spotted a tweet Monday morning about Martha, the last Passenger Pigeon, she died 100 years ago but enjoyed some degree of posthumous celebrity:

It got me wondering how many other species we know (or at least think we can identify) the last member of that species.


Booming Ben, the last Heath Hen, was last spotted in 1932, he was the last member of his species for 4 years.

Long before Ben the Heath Hen was target for early conservationists, though in a turn that would be comical if it wasn’t both bad for conservation and quite racist:

Heath hens were one of the first bird species that Americans tried to save from extinction. As early as 1791, a bill “for the preservation of heath-hen and other game” was introduced in the New York State legislature. Some representatives misinterpreted the bill when it was read as an act to protect “Indians and other heathen“; although the legislation was passed, it turned out to be unenforceable.

As recently as this April the heath hen was proposed for ‘de-extinction’ by a company called Revive and Restore. The list also includes Plesitocene megafauna that have been extinct for 4,000-10,000 years. He may not be as big and flashy but I’d say Ben has a better chance.

Benjamin, the last Thylacine

Another Benjamin, the last Thylacine, died in Hobart Zoo in 1936. I’ve posted footage of him before, and it’s well worth watching if only to see how huge Thylacine jaws really were.

Thylacines are also a candidate for the Revive and Restore project though the Tasmanian Tiger still clocks up 40-50 unconfirmed sightings a year (the link is worth checking out for the Thylacoleo and Yowie sightings info).

Celia, the last Pyrenean Ibex was found dead in 2000, you can visit her taxidermied remains and she was briefly resurrected via cloning in 2009.


Lonesome George is one of the more famous examples, a number of attempts were made to breed him with similar sub-species but none of the eggs were viable. He died in 2012 at the age of 102, he’d been an endling for at least 40 years.


This is the quite possibly the last Rabbe’s fringe-limbed treefrog, he resides at the Atlanta Botanical Garden and has been the last known member of his species for 2 years now, though the last known female died in 2009. The species was only discovered in 2005 and the last known observation “was that of a single male heard calling (but not seen) in 2007″.


This is the last female Yangtze giant softshell turtle, she lives at Suzhou Zoo in China and is the last hope for continuing her species. She’s co-resident with one of the remaining males but after hundreds of unhatched eggs over the last 6 years it was confirmed last month that “the male is either infertile, or incapable of inseminating the female.”

The other two known members of their species live in separate lakes in Vietnam, though as the article states there have been unconfirmed sightings in the Red River in Yunan Province, and as our female certainly has no problems laying eggs artificial insemination may bring some success.


This photos contains the entire breeding population of Northern White Rhinoceros. They were formerly resident at the Dvůr Králové Zoo in the Czech Republic but were reintroduced into the wild in 2009 after the species had become extinct in the wild. One rhino remains at Dvůr Králové and two are in San Diego (a male and an infertile female). The last Northern White Rhino birth was in 2000.

In reality most endlings won’t be named, or even known. There are almost 20,000 species currently at risk of extinction.
