In reply to Mike Peacock:
And in my picture, the stuff is on a rock, with the remains of a frog nearby. So, could it be:
a. The frog spontaneously exploded, and this is the result
b. Something tried to eat the frog, didn't like it, and this is the result.
c. The frog ate something that wasn't pleasant, and the something that ate the frog reacted to the thing that the the frog ate!
d. Something ate the frog, but something other than the frog, or what the frog ate, caused it to regurgitate it's legs and the "star jelly".
e. The presence of the frogs legs is purely coincidental.
f. none of the above...
The presence of the frogs legs seems like too much of a coincidence to me as well.
