Look at this beauty!
Large-bodied earthworm. Approximately 1.5 meters in length and greater than 500 grams weight. 1st and 2nd pictures are the posterior of the worm. 3rd picture is anterior of the same worm.
I found this earthworm in extremely wet rich forest soil in the foothills of Sumaco Volcano in Ecuador. Elevation ~ 1500 MASL.
