Friends for Life!

You must all have heard of the story of the rabbit and the tortoise, but the following story, is about an unusual bonding between a baby Hippo and a Centenarian Tortoise. (I learnt, the story has been in circulation on the Internet, since January, 2005). It is a different, and very touching true story, which sends a strong message, to all of us. I only yearn, that if only all humankind can live together like this, without any prejudice of status in life, religion or colour, it will be heaven on earth!

A baby hippopotamus that survived the tsunami waves on the Kenyan coast has formed a strong bond with a giant male century-old tortoise in an animal facility in the port city of Mombassa, officials said.

Bereaved by the forces of nature the baby hippopotamus, nicknamed Owen and weighing about300 kilograms (650 pounds), was swept down Sabaki River into the Indian Ocean, then forced back to shore when tsunami waves struck the Kenyan coast on December 26, before wildlife rangers rescued him. The wildlife officials were alerted to the imperilled hippo before Christmas, when hoteliers in Malindi spotted the little fellow, in the company of a number of adults of his kind, foundering in the surf off the coast. By the time wildlife officials arrived, Owen was alone, having become separated from his herd. Had he not been rescued, the ocean's waters would have done in the youngster because long immersion in salt water would have led to fatal dehydration.

As soon as the Hippo was placed in Haller Park, a wildlife sanctuary in the coastal city of Mombassa, Kenya, the orphaned youngster immediately ran to the giant tortoise also housed in that space. The tortoise, named Mzee (Swahili for "old man") and estimated to be between 100 and 130 years old, was not immediately taken with the brash newcomer he turned and hissed, forcing the hippo to back away. Yet Owen persisted in following the tortoise around the park (and even into a pool), and within days the pair had forged a friendship, eating and sleeping together. Owen has even been seen to lick the tortoise, whom he regards as his new mother. (Wildlife workers speculated that Owen may have been attracted to Mzee as a parental figure because the tortoise's shape and color are similar to those of an adult hippopotamus.)

'It is incredible. A-less-than-a-year-old hippo has adopted a male tortoise, about a century old, and the tortoise seems to be very happy with being a 'mother',' ecologist Paula Kahumbu, who is in charge of Lafarge Park , told AFP. 'After it was swept away and lost its mother, the hippo was traumatized. It had to look for something to be a surrogate mother.

Fortunately, it landed on the tortoise and established a strong bond. They swim, eat and sleep together,' the ecologist added. 'The hippo follows the tortoise exactly the way it followed its mother. If somebody approaches the tortoise, the hippo becomes aggressive, as if protecting its biological mother,' Kahumbu added. 'The hippo is a young baby, he was left at a very tender age and by nature, hippos are social animals that like to stay with their mothers for four years,' he explained.

'Life is not measured by the number of breaths we take, but by the moments that take our breath away.' This is a real story that shows that our differences don't matter much when we need the comfort of another. We could all learn a lesson from these two creatures of God, 'Look beyond the differences and find a way to walk the path together.'

As of December 2005, a year after their initial meeting, Owen and Mzee are still together. Conservation workers are planning sometime in 2006 to introduce Owen to Cleo, a 13-year-old female hippo who has gone without the companionship of her own species for over ten years.

Update:

In March 2006, the Hollywood Reporter announced that Walden Media were planning to produce "Tortoise and Hippo," a film inspired by the photograph of Owen and Mzee displayed above:

Oscar-winning special-effects maven John Dykstra is set to make his directing debut on "Tortoise and Hippo," a film inspired by a photo that circulated following the Asian tsunami.

The snapshot documented a baby hippo and 100-year-old tortoise comforting each other at a wildlife sanctuary after being rescued from the Indian Ocean.

"The actual event that inspired the movie captured the imagination of the world," said Alex Schwartz, executive VP production at Walden Media, one of the producers of the film.

"We're going to create a movie inspired by it that we hope can tell a story everyone can relate to, which is that you can be different but still belong to the same family."

A Problem Like No Other...

Watch the Al Gore's cartoon explaining the process of Global Warming...



Polar bears live only in the arctic and as the sea ice continues to melt due to global warming, the polar bears' primary habitat becomes more threatened. They are incredibly specialized hunters that have adapted to life in the Arctic environment. They depend on the sea ice for survival - it is their hunting grounds; it is their lifeblood. The polar bears featured in this movie are calling us to action as their habitat is threatened. Scientists are calling us to action as they study the current data and make concerning predictions for our future. Future generations are calling us to action as they hope to inherit a better world.

All of the images featured in this movie have been provided by Howard Ruby, Chairman of Oakwood Worldwide, the temporary housing specialist and a supporter of the Global Warming Crusade Fund, LLC. A passionate photographer, his adventures have taken him on numerous trips to the Arctic to photograph this dramatic area and the amazing polar bears and cubs that live there. After witnessing the effects of global warming first-hand and seeing the polar bears' plight, he was moved to assist Oakwood Worldwide in creating the Global Warming Crusade Fund to raise public awareness and to support various research programs and charitable organizations.






Although developed for a Thai commercial for Halls Lite drops, the following video has a hard hitting message presented in a hilarious manner. After laughing if you think a little while, you feel like saying like the famous villain Gabbar "Hamara Kya Hoga Kaaliya..."

The video shows a Polar bear shaving it's fur off to adapt to the increasing global warming. The Arctic grooming leaves polar quite embarassed and puts us to shame. Tears rolled up my eyes when i watched it the first time...


If you were a wildlife biologists, you may question, but polar bears have a black skin below their fur...!

Perhaps all the governments around the world have a similar view to global warming.

Cicada Song

Last week, I had been to Nagarhole, Rajiv Gandhi National Park (see map) and got to watch and learn from several of the marvellous creatures of nature. Cicada was one, which we frequently got the chance to observe. I was of the belief that they make their noise by rubbing their legs as the crickets and locusts do! I was wrong! They make their noise using special body part called tymbals. if you are interested in learning more about these magnificent insects, please read further!

The Insect

Cicada
(sih-kay-duh) is an insect of the order with large eyes wide apart on the head and usually transparent, well-veined wings. The adult insect, sometimes called an imago, is usually 2 to 5 cm long, although some tropical species can reach 15 cm. Cicadas have prominent eyes set wide apart on the sides of the head, short antennae protruding between or in front of the eyes, and membranous front wings. Over 2,500 species of cicada are found in temperate to tropical climates where they are among the most widely recognized of all insects, mainly due to their large size and remarkable acoustic talents.

Harmless
Although the Cicadas appear large and scary, they do not bite or sting, are benign to humans, and are not considered pests. Some people in Ancient Greece, China, Malaysia, Burma, Latin America and the Congo eat cicadas: the female is prized as it is meatier. Some of them are considered as pests, when they swarm the area in large numbers.


Did You Know?
Desert cicadas are also among the few insects known to cool themselves by sweating, while many other cicadas can voluntarily raise their body temperatures as much as 22oC above ambient temperature.


The Cicada Song

Male cicadas have loud noisemakers called "timbals" on the sides of the abdominal base. Unlike other familiar sound-producing insects like crickets their "singing" is not created by the stridulation (where two structures are rubbed against one another). The timbals are regions of the exoskeleton that are modified to form a complex membrane with thin, membranous portions and thickened "ribs". Contracting the internal timbal muscles produces a clicking sound as the timbals buckle inwards. As these muscles relax, the timbals return to their original position producing another click. The interior of the male abdomen is substantially hollow to amplify the resonance of the sound. A cicada rapidly vibrates these membranes, and enlarged chambers derived from the tracheae make its body serve as a resonance chamber, greatly amplifying the sound. They modulate their noise by wiggling their abdomens toward and away from the tree that they are on. Also, each species is known to have its own distinctive song.



Although only males produce the cicadas' distinctive sound, both sexes have tympana, which are membranous structures used to detect sounds and thus the cicadas' equivalent of ears. Males can disable their own tympana while calling. Adult cicadas have a sideways-
ridged plate where the mouth is in normal insects.

Some cicadas produce sounds up to 120 dB "at close range", among the loudest of all insect-produced sounds. Conversely, some small species are known to have songs in such high pitch, that the noise is inaudible to humans. Species have different mating songs to ensure they attract the appropriate mate. Male cicadas are also capable of making a loud squawk when disturbed. It is believed that such squawking may be effective in deterring predators. Males of many species tend to gather which creates a greater sound intensity and protects against avian predators. It can be difficult to determine which direction(s) cicada song is coming from, because the low pitch carries well and because it may, in fact, be coming from many directions at once, as cicadas in various trees all make noise at once.

In addition to the mating song, many species also have a distinct distress call, usually a somewhat broken and erratic sound emitted when an individual is seized. A number of species also have a courtship song, which is often a quieter call and is produced after a female has been drawn by the calling song.

The song of the cicada is a favourite sound effect used by filmmakers and animators as a means of representing silence, pathos, and the great outdoors.

Life Cycle

After mating, the female cuts slits into the bark of a twig, and into these she deposits her eggs. She may do so repeatedly, until she has laid several hundred eggs. When the eggs hatch, the newborn nymphs drop to the ground, where they burrow. Most cicadas go through a life cycle that lasts from two to five years. These long life cycles are an adaptation to predators such as the cicada killer wasp and praying mantis, as a predator could not regularly fall into synchrony with the cicadas.

The insects spend most of the time that they are underground as nymphs at depths ranging from about 30 cm up to 2.5 m. The nymphs feed on root juice and have strong front legs for digging. In the final nymphal instar, they construct an exit tunnel to the surface and emerge. They then moult (shed their skins), on a nearby plant for the last time and emerge as adults. The abandoned skins remain, still clinging to the bark of trees. Cicadas inhabit both native and exotic plants including tall trees, coastal mangroves, urban gardens and desert shrubs.
