Isn’t he gorgeous? He’s an Australian peacock spider (Maratus volans) and the photo is by Jürgen Otto. He has a whole gallery of even better photos of this spectacular little arachnid that you’ll want to check out. However what you really have to see is his video of the dance the males perform to attract the females (you might want to watch it on YouTube for the slightly larger format):
Absolutely wonderful images that demonstrate how apt the common name for these little spiders is. Thank you Jürgen for sharing them.

Two more episodes from the excellent television series Inside Natures Giants are now available for viewing on YouTube. As I wrote in a previous post, this is a fascinating zoology program wherein the bodies of various large animals are dissected to demonstrate the details of their anatomy. This is combined with discussions of the living animals and their natural history with occasional incites from Richard Dawkins about evolutionary biology.
First of the newly available episodes is a two for one in which both a lion and tiger are examined, contrasted and compared. Here is part one of four:
A play list for the rest of the parts can be found here.
In my previous posting on this series I wished for them to focus an episode on something like a giant squid so as to show something on invertebrate anatomy and my wish has come true. Here is part one of five:
As before I really cannot speak more highly of this program. It is fascinating television for anyone with even the slightest curiosity about the natural world and a absolute must see for anyone interested in biology, zoology and evolution.
Gush, gush, gush!
I recently stumbled upon (on YouTube) a BAFTA award winning British TV series titled Inside Natures Giants and I’ve fallen in love. What we have here is a television show in which various large animals, all vertebrates so far, are dissected on camera (and often in front of a live audience of students) by a team of biologists in order to show the details of their anatomy while presenting elements of their physiology, natural history and evolution (including commentary by evolutionary biologist Richard Dawkins).
So far the show has dissected an Asian elephant, a fin whale, a Nile crocodile, a Rothschild giraffe, a great white shark, a Burmese python, and most recently (unfortunately not yet available on YouTube) a two for one, lion and tiger combination.
These programs deal with the dissection of actual animals in graphic detail so if you’re squeamish at all you might find them difficult to watch, however this show is an absolute must see for anyone interested in zoology and evolution.
Of particular interest was the dissection of the giraffe. Among the various interesting adaptations towards tree top browsing is a classic example of one of the cloven hoofprints of evolutionary history, the recurrent laryngeal nerve; the dissection of which has apparently not been done (according to one of the scientists in the show) in a giraffe since the 1830’s.
Here is the first episode of the first series on the Asian elephant:
A play list of all the videos available on YouTube can be found here, and I really cannot recommend them more highly.
Go watch them… NOW!
My wife (Kathy) woke me up this morning telling me there was a “baby in the bathroom”. Naturally enough I asked “baby what?”. “A lizard” she said.
Now we generally have only two types of lizards around where I live (in Southern California), the Southern Alligator Lizard (Elgaria multicarinata) and the Western Fence Lizard (Sceloporus occidentalis). Usually when I find a lizard in the house it’s an alligator lizard. They’re nasty little buggers who bite (the larger ones can draw blood), wipe feces on you and drop their tails if you breath on them too hard.
So I asked my wife which kind it was. She said, rather insistently, that she didn’t know and that I should get out of bed and look for myself. Here is what I found in all its cuteness:
After briefly toying with the idea of keeping it (because it was so damn adorable) we decided to let it go in an area beside the house where we frequently see its relatives. We wished it best of luck and sent our tiny intruder on its way.
They’re Macroptychaster sea stars and apparently they go along with a whole slew of possibly newly discovered species and large specimens of previously know ones found in Antarctic waters near New Zealand by a biological survey team.
