Electron micrograph and colour coded digital images of CF of the middle stroma of stingray and shark; (a) electron micrograph of middle stroma of stingray; (b) colour coded digital image of (a); (c) electron micrograph of middle stroma of stingray; (d) colour coded digital image of (c). Please note that, in stingray, most of the CFs were in the range from 15 to 25 nm (red and green) and few of them were in the range from 25 to 30 nm (blue). In shark very few CFs were in the range from 15 to 20 nm, and most of the CFs were in the range from 20 to 30 nm (green and blue). Blue: 25–30 nm; yellow: 30–35 nm; terracotta: 35–40 nm; pink: 40–45 nm.
