The same spot than yesterday's picture
from wikipedia:
Hyenas have extremely strong jaws in relation to their body size. In 2005, Dr. Brady Barr of the National Geographic measured the bite forces of many different animals, including spotted hyenas for the documentary Dangerous Encounters: Bite Force. A one year old cub had a bite measured at 273 kilograms (603 pounds) of force, leading to the postulation that a full grown adult could bite at over 453 kilograms (1,000 pounds). This mandibular power, combined with its large pyramid shaped molars allows it to easily crush bone, even those of elephants. An experiment conducted in 1955 showed how the spotted hyena easily outclassed the the much larger brown bear in bone crushing ability.

They also have a very powerful digestive system with highly acidic fluids. This makes them capable of eating and digesting their entire prey, including skin, teeth, horns, bones and even hooves. This results in them having crusty white droppings, due to the amount of calcium they ingest. The hyenas digestive system is so efficient, it can even derive nourishment from mummified corpses. There are even reports of hyenas entering campsites and consuming aluminium pots and pans.Undigestible parts are vomited in the form of pellets.

In the wild, the spotted hyena has an average lifespan of 12 years. In captivity, it can be extended to 25.

The female Spotted Hyena's urogenital system is unique among mammals: the clitoris is elongated to form a fully erectile phallus, the vaginal opening is at the tip of this phallus. - only the shape of the glans at the tip of the phallus makes it possible to differentiate the sexes. The female urinates, mates and gives birth through this pseudo-penis. Since it is impossible to penetrate without the female's cooperation, female hyena have full control over whom they choose to mate with. The male hyena's penis lacks a baculum, a bone found in the genitals of most mammals.

Birth is very difficult: the internal birth canal extends almost to the subcaudal location of the vulva (which in Crocuta is fused to form a scrotum containing fatty pseudo-testes) before turning abruptly towards the clitoris, and the clitoris itself is narrow (although it ruptures with the first parturition, making subsequent births easier). In captivity, many cubs of primiparous mothers are stillborn because of the long labour times involved, and in the wild, it is estimated that 10% of first time mothers die during labour.[7] These factors suggests that at some point there must have been powerful selective pressures driving the evolution of masculinisation.

Hello Tom,
Great action photo. Good sharpness, composition and focus. Beautiful natural colours.

Hello Tom,
What strange animals they are... Your notes are much interesting as I learned many stunning things about hyena that I didn't know about. This picture is very strong by its action, composition and POV. A real documentary shot :) This is great and educational post. Thanks,

Hi Tom.
Great behaviour shot of the Hyena's ripping into the kill. Composition to show the feeding so detailed is great, sharp where needed on the point of interest, colour and exposure spot on.

Hi Tom

Great natural history shot with superb light. I wonder, if light was good enough, if a smaller aperture might have brought the other hyena into better focus....but often we dont have that luxury while shooting wildlife!


Hello Tom,
Graphic closeup with excellent sharpness/detail. It's a wonderful POV, you can see the hyena straining as it tears the flesh away..
I can almost hear the bones crunchin' from here ;}
Very well done.

Hi Tom,
Nice capture with a good timing. I liked the details :o)

Excellent (despite being a grizzly scene)! Great detail and info! Kudos! Cheers, Klaus

I miss a baculum too. :(
Very interesting extensive note.
excellent shot. very detailed . well composed.

Hello Tom,

What an impressive and dramatic picture!!! Do they hunt by themselves this Zebra or did they stole it to another predator?

Excellent exposition and composition! The focus is also very sharp! Maybe with a smaller aperture you would have both hyenas in focus...

Great picture and TFS!


what an action.you can feel the strength of the hyena maxillaries!
