Jackals vs Vultures
Jackals and Vultures survive on carrion, and sometimes come into savage competition for a meal. Sharp talons and ferocious beaks versus strong jaws and pointy teeth, the battles can be vicious, violent confrontations.
The carcass was put out for the vultures so that visitors to the Giants Castle Nature Reserve could view them closer, but the vultures were far too late by the time they arrived as the jackals had already claimed it. And it looks like the Jackals won this round.
Not all the fighting looks this simple and tidy. More often, a huge crowd shows up to claim the carrion, and it’s loud, rowdy, and dusty, as you can see from the following photos.
When it’s one on one, the Jackal and Vulture seem to be evenly matched in size, savagery, and vicious determination.
But, with vultures, there’s never just the one!
Sometimes, even with reinforcements, the Vultures win the meal.
But there are days when a Jackal gets the upper hand.
Beautiful Beaches That Glow In The Dark
Greek philosopher Anaximenes is thought to have made the first report of marine bioluminescence. This was back in circa 500 C.E., when he saw an inexplicable glow as his oar cut through the water at night. Modern scientific explanations describe the phenomenon as a type of chemiluminescence born when light-releasing luciferin generated by organisms interreacts with oxygen. In most, if not all, cases this reaction is accelerated by the presence of a luciferase enzyme.
Marine creatures, insects, algae, bacteria and fungi all produce the magical glow that is bioluminescence; and different species do so for different reasons – including disguise, communication, for lighting and as lure. Bacteria and fungi usually shine constantly during phases of bioluminescence, while algae and marine animals give off intermittent light. One of the most widely observed forms of the phenomenon is caused by dinoflagellates, a type of phytoplankton.
