Caption:
The shells of abalones have a low and open spiral structure, and are characterised by several open respiratory pores in a row near the shell's outer edge. The thick inner layer of the shell is composed of nacre or mother-of-pearl, which in many species is highly iridescent, giving rise to a range of strong and changeable colours, which make the shells attractive to humans as decorative objects, and as a source of colourful mother-of-pearl.
