Ed. Note: We get annoyed when people submit images pilfered from the internet, claiming to be the authors of those images. Eric Eaton provided the following explanation:
This is a still from a video I have seen circulating recently on Facebook (but of course cannot find right now). Yes, it is definitely a tailless whip scorpion (amblypygid), probably a species that lives in caves given the ultra-long appendages.
Also definitely NOT from Maryland.
Subject: What’s this bug
February 7, 2016 11:54 am
I recently saw this bug and I was wondering what it was!
Please provide us additional information on exactly where and when this Arachnid was sighted. The image was obviously taken indoors, but we are having a difficult time believing it is native to Maryland. There is not much detail in your image, and we cannot even say for certain to which order it belongs as it seems to have traits of both Harvestmen in the order Opiliones and Tailless Whipscorpions in the order Amblypygi. Tailless Whipscorpions are only reported from Arizona, Texas and Florida, and this individual does not look like any native species depicted on BugGuide. While Harvestmen are found throughout North America, we have never seen any images on BugGuide that look like this individual. It is difficult to tell from your image if the appendages that appear to end in claws are the first pair, known as pedipalps, but that is what we surmise. So, we know it is an Arachnid, and we do not believe it is native. Are you able to provide any additional images from different angles? We have contacted Eric Eaton to get his opinion.
