Sea creatures do so many things that astound us. They regrow and regenerate, they incubate eggs for years without ever eating a morsel. They can be one big individual one moment, and a multicelled colony the next. And writers like Sabrina Imbler don't see these differences from us as alien, but as jumping off points to explore selfhood, development, life and death in their new book; How Far The Light Reaches: A Life in Ten Sea Creatures.
