This species is so smooth, in fact, that amorous, gold-chain-wearing male specimens have been overhead in bars making comments like, “Say, did it hurt when you fell from heaven?” and “If I could rearrange the alphabet, I’d put ‘U’ and ‘I’ together.” Okay, maybe T. derasa isn’t that kind of smooth, but its shell does lack pronounced ridges or scutes, making it relatively smooth to the touch.
