A freshwater jellyfish usually found in the Amazon has been discovered in a flooded clay pit in land-locked Leicestershire.
But pike anglers are not being linked to the find at present, as scientists puzzle over how the 2cm-dia creature could have been translocated thousands of miles across the Atlantic.
Being small, transparent and made of um, err, jelly; they lack visual appeal and would not, in any case survive a decent cast. So pike fishing for once appears to be in the clear for now.
Experts think the species (craspedacusta sowerbii) was imported to Britain on plants brought to Kew Gardens from Brazil in the 1830s.
There have been other sightings of the jellyfish - the most recent was in Wigan, Lancs last month.
