WildCreatures

This sanctuary in the Galapagos Islands takes in goats, horses, donkeys, chickens and any other animal that need a safe home. It provides the animals with food, shelter, safety, and a chance to interact with guests who come here. The sanctuary relies on donations and the money generated from the tours so they can give the animals the care they deserve. This family has brought their Canadian friends for a tour and the girls show them how the goats go crazy for bananas. The animals get lots of hay and other food, but the bananas are a special treat. The bananas hang outside the fence to allow guests to interact and feed the animals. This goat has learned how to stick his head out over the fence and show his pleading eyes for the maximum effect on the soft hearted guests. Goats will eat almost anything and these ones are no exception. They are particularly fond of the banana skins as well as the fruit inside.

Decorator crabs are known for their ability to attach algae and small animals to their shells to conceal themselves from predators, but the process is more complex than it appears, and it suggests higher intelligence than we once understood these crabs to have. If the shells of these crabs are cleaned, they will immediately set about replacing their camouflage with the same care and precision as they showed in their first concealment. There are several species of crabs that use plants, animals, and debris from their environment to adorn their shells. Some chew the algae and then carefully hook the pieces onto velcro-like hooks on their shell. They occasionally use anemones or other sedentary animals. They attach the matter to their shells with great precision and care, suggesting that they are purposefully imitating the surfaces around them. When moved from one environment to another, these crabs will quickly replace their adornments with items from the new location, seemingly understanding the need to blend in with specific surroundings. Their disguise is not random or haphazard. Decorator crabs will make use of toxic plants or animals as further deterrence for potential predators. Described by scientists as "perhaps unrivalled" mastery of concealment, these are highly specialized behaviours. Understanding the purpose of their covering, these crabs remain still during the day and they freeze in place when threatened. Some species use only sponges, others use only noxious alga. One species selects stinging anemone for it's protective covering. The anemone benefits from an increased supply of food that is available as it moves around with the crab. Octopus have shown a tendency to avoid these crabs when they are adorned with anemone. The intelligence and purpose of the smallest and seemingly less significant animals is becoming more understood. Perhaps, as we gain greater insight we will also gain greater appreciation and desire to protect them. The balance of nature is a delicate one and humans frequently disrupt this balance in their ignorance of what goes on around them.

Shark feeds are controversial in the minds of many people, however, the role they play in shark conservation and education is undeniable. The positive aspects are often underestimated. Once sought for food and sold in illegal fin trafficking, sharks were harvested in greater numbers. People in many countries simply cannot resist the income that is provided and their survival makes the ethical dilemma impossible to consider. Eco tourism provides an alternative to harvesting the sharks. While it can be argued that the sharks should not be taught to associate humans with food, these shark dives do provide an incentive to conserve sharks. They are worth more alive than dead. It's a debate with many perspectives. These divers witnessed what happens when a few scraps are held in a bucket and later released. It's a small and controlled feeding that provides an injection of dollars into a struggling economy. It is also an experience that leaves many divers with a new appreciation for the beauty of sharks. We see here that the sharks pose no threat to the divers, dispelling the myth that they are cold blooded killers, ready to eat anything or anyone they encounter. Sharks play a crucial role in the health of the reef, the ocean, and the planet. If we lose sharks, we will not survive. Understanding and appreciation is the first step in developing the needed respect for sharks. The balance of nature is fragile and we have a great responsibility to avoid upsetting it.

Kugel fountains are often called floating sphere fountains but the sphere is not actually floating. It is held in place by pressurized water that forms a thin film on which the sphere aquaplanes. These are water features or sculptures where the sphere sits in a fitted hollow in a pedestal. Pressurized water flows between the sphere and socket, creating a mechanical hydrostatic bearing that is nearly frictionless. These spheres can weigh thousands of kilograms, but the efficient bearing allows them to be spun by the force of a hand. The sphere does not float, being denser than water. They are often made from granite. The hydraulics of the fountain can be controlled so that the axis of rotation of the sphere changes continually. This kugel fountain sits outside the Guinness Book of World Records Museum in Niagara Falls, Canada. The sphere is massive, weighing more than 4,500kg (10,000lbs) and measuring almost 2m (6 feet) in diameter but a person can apply a small amount of pressure to stop the ball from rotating. The direction of the sphere can be changed easily. It is a true feat of engineering to manufacture such a precise structure that the water can hold it off the pedestal. These guests to Niagara Falls found this structure very fascinating as they figured out the principle behind it. They posed for pictures with it as they began to understand what they were seeing. Kugel fountains can be found all over the world. Many are at popular tourist destinations, such as science museums, shopping centers, lobbies, and gardens. With a little imagination, there is no end to what the human mind can invent.
