While I am writing the rest of the cancer story, the tadpoles are growing. Some have two legs, a very few have four, most are still small tadpoles, heads and tails. There seems to be no rhyme or reason to their development. In the same batch there are large tadpoles with no legs and small tadpoles with legs budding. Here is one with two legs. Notice that its body is toad like.
Here is one with four legs and with it a surprise.
