The meaning of a sentence. "They are crawling back into the sea from whence they came, ..."
I'm reading the book 'How to train your dragon. It's a very interesting book but a bit hard as well at least to me.
Sometimes there are some sentences a bit hard to understand, so please help with that.
Thank you in advance.
『You will have to take my word for it, for the dragons are disappearing so fast they may soon become extinct.
Nobody knows what is happening. They are crawling back into the sea from whence they came, leaving not a bone, not a fang, in the earth for the men of the future to remember them by.』
They are crawling back into the sea from whence they came, leaving not a bone, not a fang, in the earth for the men of the future to remember them by.
Is this mean that they were born from sea and dive to the sea when they die? And then they become fossils?
Or what does that mean?
