Anyway I decided that now was a good time to try out the "bald look" and so I got to a proper barber and had my hair shaved off completely. It was truly liberating. I took several pictures of myself at this time with the reptiles at the croc bank to remember my days here and also to record for posterity my new look. I felt truly sorry when it was time for me to leave Croc Bank. I promised everyone that I'd be back soon. I carried a souvenir with me-a red-eared turtle (which I still have) and some turtle eggs. I travelled through the night on a bus to Bangalore. At my foot was the turtle in a box and I had left a small opening for her to breathe. Suddenly I noticed that the turtle was out and was already making for the door of the bus. I quickly caught her and put her back without any of the sleeping passengers noticing it except for a dear old lady who smiled and said, "Dropped your water bottle, son?" Field Work Notes: Crocodiles Living millions of years before man, but today facing extinction...with many myths about them and very little known about their nature. Many are considered dangerous. None are considered useful. Who are these creatures? They are called crocodiles, alligators and lizards. There are 21 species of crocodiles and alligators in the world. Three species of crocodiles are found in India, namely: 1) the Gharials-which are fish-eating crocodiles; 2) the Muggers; and 3) the Salt-water crocodiles. The biggest and the most dangerous of all crocodiles in the world is the salt water crocodile, which can grow upto 25 feet. It is the only crocodile that can live in the sea for a long time. The Nile crocodile of Africa is yet another deadly species. Fossils of three other extinct species of crocodiles have also been found in India. These cold blooded animals have evolved with dinosaurs millions of years ago and are more closely related to birds than to snakes or reptiles. Being cold blooded they control their body temperature by seeking shady, sunny spots or different levels in water. They often bask with their jaws open, which probably helps them to keep cool. Their eyes, nose and ears are positioned in a straight line along with head and snout. They have good eyesight and a good sense of smell, and can hear very well. Their tail is very strong and helps them in swimming. They have a very low metabolic rate and thus need to hunt only every few days. They can decrease their metabolic rate and stay under water for a long time. Alligators have been known to stay under water for upto 6 hours. They do not make any unnecessary movements but can move very fast even on land when necessary. Small salties can gallop at a speed of 48 kph for short distances.
