As if it is not challenging enough to crochet a coral reef, the Institute for Figuring has developed a crochet version of a bleached coral reef (right).
The miniature reef is complete with what appear to be a variety of species of bleached and dead corals. I believe that's a recently deceased Acropora in the centre.
Their art installations also include a "toxic reef" made of a mixture of plastic and yarn. The jellyfish is impressive.
