Fish scale the surface, interacting only with the riblet tips, not causing any high-veloctiy flow in the valleys. Since this high velocity flow now only interacts with the riblet-tip, which is a very small surface area, the momentum transfer which causes drag is now much lower than before, thereby effectively reducing drag. Also, this reduces the cross-stream velocity fluctuations, which aids in momentum transfer too. The rough, sandpaper-like texture of shark and ray skin, coupled with its toughness, has led it to be valued as a source of rawhide leather, called shagreen. One of the many historical applications of shark shagreen was
Skin Deep (webcomic) year 2000 and two of latest stories take place in 2005. There are 9 short stories in the Skin Deep Archives, with them expanding upon Character bios and World-building. Bing has run three Kickstarter campaigns to collect the comic in print, one for each volume. Skin Deep (webcomic) Skin Deep is a fantasy webcomic series written and drawn by Missourian Kory Bing. The story follows the lives of various mythical creatures, such as a gryphon, a nixie, a satyr, and a sphinx, as they disguise themselves (using magical medallions) into the world of humans. The story's narrative, which began its
