Tadpoles Grow Legs

I haven't posted any pictures of the tadpoles for a while. Apart from getting bigger and developing more color and shape, they've been fairly static. But they've finally started to grow legs. They went from egg to tadpole so fast that I thought their whole development would be faster but they've stayed in the tadpole stage longer than I expected. (I released several batches of them as they grew and the aquarium got too crowded.)

These aren't great pictures - between lighting, reflections, focus, and moving targets it's tricky. But they suffice to show what's happening.

You can click on the pictures to get a larger view. As you can see, there's quite a lot of variation in size and stage of development, even though they're all from the same batch of eggs.

It's interesting to compare these pictures to the first batch.

Now I'm waiting for the arms to show up :-)

PS. The next day I see one of the tadpoles has arms! Either they emerged overnight, or else that tadpole had been hiding. I'll try for some pictures once a few more of them develop arms. I'm not sure when they transition to breathing air, but I added a ramp so they can get out of the water when they need to.

PPS. What does this have to do with "adventure"? To me, nature is a big and integral part of adventure. And an appreciation and knowledge of nature enhances our adventures.
