An egg with a mission

Austrolebias charrua (Canal Andreoni)I don’t know if it is very easy to spot, but on this photograph an egg with a developed embryo. You can see its right eye and it’s an Austrolebias charrua (“Canal Andreoni”) from peat collected in June 2018. Particular about this embryo is that it overwintered without heating, in a box with peat standing next to the cold tanks. It has been at temperatures as low as 4C, maybe even 2C. I will try to convince it to hatch in April, when night temperatures in the garden house rise above 10C.
