Prehistoric mini monsters

And so the clumps of spawn are increasing. I honestly don't ever remember seeing so much of the stuff; it seems that the frogs are in hyperactive mode and as each nucleus grows from a dot to a dash, more eggs are laid just to make sure. And in the warmest spots, there are tadpoles, those strange black spermy wrigglers that headbutt each other in their frenzied acknowledgement of life.
It's incredibly hard taking a decent photo of tadpoles - not just because they are in constant movement - but because the surface of the water reflects the photographer from most angles in preference to the beasts below. But there they hover, in primordial gloop, safe from the jam jar if not from natural predators.
