As is usual our pond had been overflowing with tadpoles and despite the appetite of our numerous goldfish, a fair number survive. They do actually have a small pool that's separated from the main pond by rocks, not that all of them stay within their safe area.
But this year, as my wife and I were enjoying the assorted plants that frequent the shallow water we spotted several huge tadpoles. They were easily twice the size of normal tadpoles and it wasn't long before we discovered quite a few of them.
Piqued by curiosity I tried to photgraph them in situ but they shot off or buried themselves in the mud as soon as I closed in but nothing daunted I found a small net and with just a few scoops I rounded up enough to photograph in a controlled environment.
Now, I would attach the photos that I took but despite reducing them to less than 1mb in size they've been rejected so, for now at least, you'll have to accept my words - that the tadpoles (which all possess back legs) are all around 2" long, or even more.
To me they're unusual - but to you?? Any thoughts will be appreciated. Thanks
Seen it all. Done it all. Can't remember most of it.
They might possibly be tadpoles that didn't make it to maturity in time last year and so simply stayed overwinter in your pond.
Another option is that they just hatched sooner. I've got tadpoles of varying sizes, because the spawn which was in sunlight developed much quicker than that in the shade. My pond is in complete shade all winter, and the sunlight gradually creeps across it as Spring arrives. Some spawn was weeks behind the rest.
