The Bat-Eared Fox – Did You Ever See a Fox Fly?

Saturday, 26 May 2018

Around 800,000 years ago a species developed on the African Savannah, a canid but quite unlike any other. It was small – with a head and body length of only around 55 cm, tawny furred and with black ears. It is the ears which really make this mostly nocturnal animal stand out.  On average they are a staggering 14 centimeters in length.  Proportionally they may not be as large as Dumbo’s but this is no fictional appendage. These ears are for real.

The Frog that Turns Blue

Saturday, 19 May 2018

The Moor Frog is a small and rather unprepossessing amphibian. They grow up to seven centimeters in length and are a reddish-brown color. However, all that changes once a year between March and June. It is then that the male of the species turns blue.

Here you can see the ‘before’ and ‘after’ colors of the male.

The Spiders That Decorate Their Own Webs

Saturday, 12 May 2018

Spider webs – possibly the most beautiful and intricate animal structures of the natural world. However, some spiders are not content with a simple web. They go one step further.

Some spiders decorate their own webs with even more elaborate and complex patterns than are necessary.  Could they be the best exterior designers on the planet?  Certainly from the look of these examples, they would be in the competition but the verdict is still out as to why they produce these extra web configurations.  Some scientists argue that it is nothing more than ’spidey’ aesthetics.  Take a look at some of these arachnid designs and come to your own conclusions.

Pink Dolphins on Parade

Sunday, 6 May 2018

Dumbo famously featured pink elephants, but did you know that there was a pink dolphin? In their wild habitat of the Amazon River they are quite happy to meet and greet those willing to forego a few fish for the pleasure of their company.

Also known as the Amazon River Dolphin this friendly and gregarious species is found not only in the river from which it gets one of its names.

It can also be seen in the Orinoco and the Araguaia Rivers – in fact its range covers six South American countries.

The Story of the Mountain Pine Beetle

Sunday, 29 April 2018


This is the story of a tiny insect smaller than a grain of rice – in a way it’s the circle of life writ very, very small. A native of North America, the species has recently been having something of a feast and the mountain pine beetle has reproduced to plague proportions. They have now killed most of the mature pine trees in an area the size of Wyoming.  The people at the Ruckelshaus Institute guide us through the story and the possible future of the mountain pine beetle.

You Don't Bring Me Flowers Anymore

Saturday, 28 April 2018

This alligator in Florida was captured on camera by Flickr user Marc Barrison.  While we should really - at all costs - avoid anthropomorphism, when you see a picture of an alligator with flowers on its head its is really hard to resist the temptation.  It might be hard to take an apex predator seriously with such a pretty bonnet but I would imagine that if it chose to lunge - flowers or no - we might not be the ones having the last laugh!

The Sand Cat – Desert Cat Extraordinaire

Saturday, 21 April 2018

Don’t be fooled by the off the scale cuteness quotient. This is the Sand Cat – or Felis margarita, a little known species of desert cat. In the wild it lives in areas that are too hot and dry for any other cat- the deserts of Africa and Asia, including the Sahara. It is the only desert species of cat known to us. As such, this cat is one tough cookie.

It also lives in the Arabian desert and those of Iran and Pakistan, yet despite being so widespread it was not described by a European until 1858. That happened to be one Victor Loche, a French soldier and naturalist who explored the Northern Sahara and found the sand cat waiting patiently there for his descriptive skills.

The Hellbender: Giant Salamander of the United States

Friday, 6 April 2018

When you think about where giant salamanders come from, most people would normally associate them with China and Japan.  Yet while it is true that almost all members of the giant salamander family, the Cryptobranchidae, originate in Asia there is one species which calls the eastern United States its home.  It is Cryptobranchus alleganiensis, known otherwise and popularly as the hellbender.

Why this giant salamander, which can grow up to 30 inches in length, acquired this name is lost to history.  Some say it is because of its strange looks which bewildered early European settlers who imagined that it was a creature from the underworld, bent on returning there.  While this is hardly fair, it is not its only unflattering moniker: it also goes by the names mud-devil, devil-dog and more recently, the snotty otter.  The first name, as we shall see is the most inaccurate: the hellbender doesn’t like mud one little bit.

The Desert Rain Frog: The Frog That Squeaks

Saturday, 10 March 2018


Meanwhile, over in Africa, a critically endangered species of frog has caught the world’s attention.  Endemic to just a 10 kilometer stretch between the countries of South Africa and Namibia, this small amphibian does not croak or rivvit – it squeaks.  Play the video above to see for yourself.  It sounds just like one of those squeaky toys you might give a dog to play with.

Squeaking aside for the moment, the Latin name for the desert rain frog is Berviceps macrops and it lives on a narrow strip of sandy shore between the sea and the dunes.  It lives mostly under the ground but when the fog drifts in from the ocean it takes to the surface and emits its war cry.  This may be enough to frighten off others of its species but it has become a long-lived meme on the internet.


Fortunately, it’s unlikely that many will venture to its sandy habitat to steal specimens.  Yet its environment is threatened both by industry and encroaching human populations.  It is difficult to find as it is nocturnal – even though it leaves behind it very distinctive ‘foot’ prints. These are usually discovered around heaps of animal dung – the frog is thought to live off the small insects which congregate around this matter.

It seems it is the misty air which keeps the frog’s skin moist – the areas where it is found get over 100 foggy days each year.  There are no pools for tadpoles, however; the young are laid under the ground and emerge at the surface as fully-formed if tiny desert rain frogs.  When they are seen above ground, they often have sand stuck to their skin.

Perhaps that’s why they get so angry.  It isn’t known really whether this is a warning, a mating song or something else.  One can only hope that the desert rain frog continues to squeak its way through the millennia despite our best efforts to destroy its habitat.

Why Conserve Biodiversity?

Tuesday, 27 February 2018


There are millions of species on the planet, right? So, surely we can spare a few of them!  Directed by Luis Navarro for Divulagare, this animated short documentary takes four minutes to explain very clearly why the conservation of our planet’s biodiversity is of paramount importance to us all.  Think of an ecological butterfly effect and you (ort of) get the picture.  Enough of me trying to explain – press play!

Peacock Spider – Australia’s Show Off Super Hero Spider

Sunday, 18 February 2018


Australia is home to many strange and unusual animals, something the majority of us know. When asked, most people would say that it is the marsupials of the country that are the most significantly different to the rest of the world.  Perhaps that assumption should be questioned – Australia is also home to the tiny Peacock Spider, whose behaviour and appearance is nothing short of startling.

Nature’s Fearless Fighting Machines – Superb Photography

Saturday, 3 February 2018

Animals fight for a variety of reasons. It may be for play, for space or, most likely, for sexual dominance. Here, with the help of some wonderful images – we take a look at a few species in the throes of fighting.

A pair of gulls fight in mid-air. Conflict is incredibly commonplace within the animal kingdom. Quite often the fights are short and based on display rather than actual physical contact and so it is difficult to capture on film. The photographer must be incredibly quick in order to get that photograph. This particular spat, for example, would have been over in seconds.

The Sand Dollar – the Animal that Can Clone Itself

Sunday, 14 January 2018


This somewhat strange looking specimen is a Sand dollar. It is a sea urchin which burrows and comes from the order Clypeasteroida – and you can see why it gets its name, as it resembles a coin.  Some joke that it is the only stable dollar in the world at the moment.  Humor aside, it does have one trick up its sleeve that we can only wish would apply to real money.  It can clone itself – creating a perfect copy.

What Are Those Things on Giraffes’ Heads?

Sunday, 7 January 2018

Are they antlers? Perhaps they are horns?  They are definitely not antenna – the Serengeti is not (as far as we know) wired for giraffid telecommunications.  They are called ossicones – and giraffes are born with them.
