"The Erotic Anesthesia of Sea Urchins" is a tender narrative. It reveals men's need for the delicate erotic touch. It also suggests an alternative interpretation of the apparent hardness of males.

The storytelling of the episodes helps in a condensed approach to unfortunate loves. The comfort of attributing anthropomorphic characteristics to rocks, crabs, corals, seaweeds, etc., also makes it easier for even the most stubborn phallocentric to listen to the book’s ideas as a children's tale. Their understanding may come later, equally simply.
