Over thirty years ago seven impressive elephant bulls, all with tusks weighing more than 50 kg each, could be found in Kruger National Park. The Chief Warden at the time, Dr U de V Pienaar, decided to publicise these elephants as a successful example of Kruger's conservation work. He named those bulls that had not already been identified and also coined the collective name, the Magnificent Seven, based on the 1960 Hollywood film. The promotion was launched in 1980 with specially commissioned paintings by celebrated wildlife artist Paul Bosman and illustrated articles written by the park's Senior Research Officer, Dr Anthony Hall-Martin. The public reaction was staggering and, when each of these great elephants died, it was decided to retrieve their tusks and skulls in order to display them. The Elephant Hall at Letaba Rest Camp now holds the tusks of Dzombo, Kambaku, Mafunyane, Ndlulamithi, Shawu and Shingwedzi.
Internal organs: The Brain The brain of an adult elephant is the largest of any land mammal and weighs 4-6 kg. This is about 0.1% of its entire body mass. Although human brains are a lot lighter (about 1.5 kg), they make up a greater proportion of body weight (2%). The temporal lobes, known to function as memory centres are quite large in elephants. Like humans, elephant babies have much smaller brains than those of adults. In most mammals a new-born brain is around 90% of the size of an adult's. In elephants it is 35% and in humans 26%. This probably explains the remarkable learning ability of young elephants.
Stomach Only about 44% of the food that an elephant eats is successfully digested. The rest is excreted - take a close look at some elephant dung and you will see undigested grass, seeds and other plant matter. Elephants eat for around 16 hours a day and a large bull needs about 300 kg of food each day.
Heart An elephant heart can weigh anything from 12 to 28 kgs but amounts to only about 0.5% of the animal's body weight. It has a unique shape with two, rather than one, points. The heart beats at around 25-30 beats per minute when the animal is standing, increasing slightly when it is lying down. This is much slower than a human heart which averages 70 beats per minute. Some of an elephant's blood vessels can be over 3m long. In order to prevent their collapse, the animal needs to retain a high blood pressure.
Intestines The small and large intestines may reach a combined length of 35m. As food works its way through this system, it can take 24 hours to digest a meal.
Lungs Elephants take about 4-5 breaths per minute when lying or very calm. This increases to 10 breaths per minute when standing or active (at rest humans take between 12-20 breaths per minute). The lungs attach directly to the chest cavity and to the diaphragm. Unlike other animals (which use pressure changes to breathe in and out), elephants use muscles to inflate and deflate their lungs.
Bladder An elephant expels about 50 litres of urine a day.
Anus An elephant excretes up to 150 kg of waste a day.
External biology Mouth Elephants breathe through their mouth when their trunk is being used to hold water or dust. African elephants have 6 sets of molar teeth throughout their life. As each set wears down, a new set grows behind it, moving forwards and upwards. As the old teeth are pushed out, the roots are reabsorbed into the jaw. When elephants eat their jaws and teeth move forwards and backwards not side to side like other herbivores. There are well-developed salivary glands in the mouth which help to lubricate the coarse vegetation of the elephant's diet.

Housing Ground Dwellers — a fish tank 12 x 12 x 12-inch with a lid is adequate—I stress WITH A LID since tarantulas are great escapologists! Cover the bottom with VERMICULITE well wetted —this is the best medium for tarantulas since it is completely germ and mite free and holds humidity. A heating pad placed under the tank and controlled by thermostat will keep the tank to the correct temperature (around 75°F for most ground dwellers—slightly warmer for some species and more humid). A spray of the tank daily will keep the humidity at the correct level. Housing Arboreal Spiders — the tank and stratum need to be the same as for ground dwellers but remember that these spiders do climb so a tank which is higher would be preferable. The spider will need twigs or the like to suspend its arboreal nest. (You can compare the size of this one to the mans hand.) 
Feeding — you cannot overfeed a tarantula since it will only eat what it needs. Feeding consists of crickets, locusts, cockroaches etc. It will also eat giant mealworms sometimes and most tarantulas will take a piece of raw fat-free beef occasionally. Fresh water should ALWAYS be available. A small low dish either filled with soaked cotton wool or purely open water will suffice for most spiders. Arboreal spiders prefer to drink from the tank walls or the twigs so that a spray of their tank every day is most essential. Loners — spiders should ALWAYS be housed alone as they will fight and even kill one another. If you have a large enough tank you can insert a divider thereby enabling you to keep two in one tank. They do not need a great deal of space. Most spiders do not travel more than four feet in a lifetime. Moulting — a web is spun to make a mat upon which to lay to shed the skin so that is a first sign. The spider will usually not have eaten for some few weeks, even months, before the moult and the bald patch on the abdomen will turn blue-black. The spider will flip over onto its back—DO NOT TOUCH IT — but make sure there is no live food in the tank which can disturb and even nibble at the moulting spider. The moult itself can take several hours and once complete the spider will flip back over onto its feet. It will be very tired for several days and you should not touch the spider dyring this time or, indeed, until it starts feeding again. Offer food after three or four days but do not worry if it does not immediately snare its prey. If you treat your tarantula correctly and with tender care, it will be with you for many years, the females living the longest. Another important thing to remember is that tarantulas neither like nor do they need bright lights. The spider's home should be in a darkish corner making sure that the sun does not pass over the tank. ALWAYS keep the tank out of reach of toddlers and young children.

(There was also this beautiful Iguana. This one is about 2 1/2 feet in length and not a pet for children as even the man had difficulty holding and controlling it.) 
The second is Klaas’s Cuckoo which has only a small white stripe from the brown eye, backwards. It also has spots instead of bars on its chest.
