Most of us are used to seeing enormous trucks driving along the main roads, carrying various loads from one place to another. The mechanical horse and trailer fit together like a cup and saucer – until one comes across a mechanical horse sans trailer, then it looks odd: too big to have what appears to be such a short wheel-base; the cab set far too high … the same applies to a gecko or a lizard that has lost its tail. Look at this one:
These marvellous creatures can sever their tails as a form of self-defence as the wriggling tail is quite likely to distract its predator. This self-amputation is known as autotomy (from the Greek ‘self’ and ‘sever’). There is no blood loss, and the tail regrows over several months. I have seen some with forked tails or rather skew tails too – possibly because they have not regrown properly.
