This is a great piece of work by the Horniman and well worth a visit if ever you get chance for a behind the scenes visit.


I want to know about ‘tadpole husbandry’! It’s mentioned on one of the display panels in the aquarium. They have frogs so it makes sense that they breed them too, but it’s amusing to imagine someone ernestly rearing tadpoles.

Good work

“Tadpole husbandry” makes me think of what we used to do in primary school when the whole class would collect jam jars of frog spawn and take back to the classroom to watch the development of the tadpoles. I remember the competitive excitement to see whose tadpokes were the first to grow legs but don’t recall any turning into frogs. I think mine ate one another. All pretty gross and rather sad. I expect it’s a lot more sophisticated and humane nowadays.

I do have some photos of our class on our rather mucky (and murderous) school nature ramble.
