I have written a lot about the camels during last 20 years. Mainly, I have compiled my own observation and research about the camels. A huge part of my writeup is also derived from the publications and literature published globally. Once, I wrote an article that camel have the characters from many different animals, therefore camel is unique. https://arkbiodiv.com/natures-engineered-a-unique-biological-model/
Today, I was reading a book about the snakes. I realized that camel have some characteristics like snakes or reptiles. Camel is a kind of Ectotherm; this means that they regulate their body temperature with the environment. That is why the camels need lesser energy requirements compared to other livestock.
