[2] From the original letter: The animal is of nocturnal habits, and it's said to be so strong that it can seize horses with its claws and drag them to the bottom of the water.
Its tail is long, flat and prehensile.During follow-up research by Bernard Heuvelmans, the local population described the iemisch as a mixture of a jaguar and otter, though by some accounts it was as big as an ox.
[1] Robert Lehmann-Nitsche, a German anthropologist working in Argentina, claimed to have a sample of the iemisch's skin given to him by a local rancher.
[1] Robert Lehmann-Nitsche and Santiago Roth would eventually publish more iemisch tales in their work The Mysterious Mammal of Patagonia, Grypotherium Domesticum.
Upon peer review, contemporaries of Nitsche and Roth noted that though they had spent equal amounts of time with Patagonian natives, they had never heard of such a creature.
