The top photographs show, to the left, the Purple Idmonea, with coral-like colonies about one inch in length of a chalky 
substance with a purple-tinted and glassy surface; to the right, the Snowy Dish, whose colony measures about a quarter of an 
inch across and forms a stony disc. Below, to the right, is the Fringed Sea-Scurf, which lives in tufts half an ir high on 
seaweed, and to the left the Paper Sea Mat, often mistaken for a seaweed.
