Absolutely, but I thought that difference in terminology only existed in British English and that American English used the word "turtle" for both the land and water-borne varieties? Or is it just that people falsely use "turtle" for everything?
There was a big stink here a while ago when someone phoned the RSPCA (Royal Society for the Prevention of Cruelty to Animals, a society that basically does lots of different things for animals) to say they found a "turtle" in their back garden. They came, collected the "turtle", put it in a bucket of water, and it drowned. The person involved got sacked for not being able to tell the difference between a turtle and a tortoise which is, it has to be said, a very difficult mistake to make - they tend to look distinctly different.
Too right - can't bear the thought of someone buying it to put in a pot...
