Star Jelly

Observed: 11th February 2011 By: david cuniondavid cunion’s reputation in Amphibians and Reptiles

Several clumps of translucent/ white jelly on margin of reedy rivulet (not peaty), perhaps 7-8 in all over 100 yards. One appears to have animal tissue firmly embedded:?intestine or maybe (frog?) oviduct. I was able to tease out another lump, which looks like a continuous sausage. as in the last photograph.

Star Jelly

Thanks. At home, left overnight in rainwater, it doubled in volume, and the linearity was more apparent. Definitely non-luminous(!)

The BBC featured this .......

on a programme and talked to scientists. The outcome seemed to be that Star Jelly is the ovaries of Frogs left by a predator, bird of prey, as being unpalatable.

I looked on the BBC website but can't find a reference but is was Radio 4 a couple of months ago.

Star Jelly ? Frogs innards ?

The Jelly was spotted first and 60 yards away I found the Frog near one of our ponds either it was discarded or I disturbed a predator.
