I believe both are considered spieces of concern due to dwindling populations and care in captivity. Both are carnivores. Both lure prey with an appendage that hans in front of them. Sorry, no pics.
i have seen a recent influx of these at my lf's... one was being badly beaten up by a trigger. Another got sold to the first person who saw it and the last one looked sickly and i think died in the store. I'd love to have one but dont know nearly enough about them.
