Re: Anyone know....
"...what that little backpack is attached to the toad in the photo? It's quite prominent in the picture, almost as if that was the whole point of taking that specific photo, but not referenced at all in the story."
Well, it's referenced in the fine caption under the photo (which is where captions usually sit):
'This is a cane toad with a tracking device attached at a dam in Australia'. Some days being a caption writer is OK.
To which I'd add... "and most days, being a caption writer is thankless because NO ONE APPARENTLY BOTHERS TO READ THEM." :)
